Chimera is the update to Halo: Combat Evolved for the PC that we should have had but never got.

Here is the installation procedure for installing Chimera:
strings-old.dll works.NOTE: Each file goes into the main game folder, NOT controls. If you put the files in controls, it will not work.
Uninstalling Chimera is simple:
strings.dll.You can install binary mods (i.e. dlls) by creating a folder called "mods" and copying the dlls into the directory.
NOTE: Chimera does not support dll mods including HAC2 or Open Sauce. This is because they modify the game in similar ways, resulting in them conflicting with one another. Supporting just one of these mods would mean extra development time that we don't have. Sorry.
Chimera provides a number of features and enhancements to the base Halo game. To ensure the base game is preserved as much as possible, most features are not turned on by default, and the ones that are only exist to enhance or fix the game.
These are features that are always on.
The game has an issue where object movement is tied to tick rate, thus objects will never move faster than 30 frames per second. Chimera adds interpolation to the game for objects and other effects.
Chimera increases some of the limits of the game. Note that, unless you play a map that exceeds these limits, your performance will not be impacted. If you don't have this on, then maps that exceed the limits will look incorrect and may not even be playable. Therefore, this feature is always on. Here are the increases:
Chimera supports maps compressed with the chimera-compress compression tool. This allows you to take advantage of the blazingly fast zstd compression algorithm, drastically cutting down map size.
If maps in RAM is enabled, compressed maps will be decompressed directly into RAM. Otherwise, temp files will be used (placed in Chimera's folder).
Normally, Halo Custom Edition does not display a "campaign" option on the main menu. If all of the campaign maps are availible in the maps folder, Chimera will reenable the "campaign" option just like in the retail version.
Chimera fixes a bug where camera shaking does not work at high frame rates.
Chimera fixes a bug where checkpoints time out too fast at high frame rates.
Normally, Halo does not allow you to join servers with someone that has the same CD key. This was done to prevent people from sharing CD keys. However, this protection has shown to not work and, as a result, is purely an hindrance to people who have legitimate copies of the game, such as modders. By disabling the CD key check, you can locally host a game that lets you join yourself. Also, because a large number of players do not own legitimate copies of the game, having the CD key check in place will likely prevent you from getting any players in the first place.
Note that this feature does not "crack" the game. You still need a valid Halo installation in order to run the installer for the game as well as update the game to 1.10.
When you take damage while zoomed in, the game zooms back out automatically. This functionality is broken when in a server, as the client only descopes when the player takes damage on the client instance rather than if they actually took damage on the server. Chimera changes this to making it so if you lose health or shield, you are descoped.
Chimera fixes a bug where the "About" button of the profile settings menu doesn't display the correct bitmap in the extended description.
Halo Custom Edition CRC32s every map on startup. On a small maps folder, this does not significantly increase loading time. On a massive maps folder, this drastically increases loading time, ranging from seconds to minutes.
Some mods "fix" this by storing the CRC32 in a cache, but this negates the point of it in the first place, as now you can join servers with mismatched CRC32s. Chimera truly fixes it by CRC32ing the map when you load the map, not the game.
The game takes forever to query the master server. Chimera speeds it up.
If you load a map that exceeds 128 MiB, the game opens the map multiple times and only closes it once. This results in the map leaking, and eventually, the game could run out of file descriptors. Chimera fixes this by removing the file size check.
The game uses your vertical resolution to determine how detailed to draw a model. However, this results in levels like The Pillar of Autumn showing the highest LOD for some mods when it shouldn't, leading to infamous glitches like the "4K headless chief" glitch. Chimera makes it scale by 480p, instead.
There is a bug in the game where, when you increase the vertical resolution of
the game, your FOV gets slightly more narrow, even if you are on the same
aspect ratio. Chimera fixes this so FOVs stay consistent between vertical
resolutions. This does NOT fix low FOV at widescreen aspect ratios, which is
what chimera_fov is for.
Lens flares are drawn at a set number of pixels regardless of vertical resolution. Chimera makes it scale by 768p, instead.
The Keystone chat is crashy and broken. Chimera adds a replacement chat.
Chimera fixes a bug where, if the GPU is an NVIDIA graphics card, it uses alpha blended camo instead of the liquid camo shader.
Chimera fixes a bug where contrails are bugged at high frame rates.
Chimera fixes a bug where the motion sensor fade is incorrect at >30 FPS
Fog in maps such as Assault on the Control Room's sky fog now works as intended.
The "detail after reflection" flag in model shaders now works as intended.
HUD numbers are no longer drawn oversized if modified to be a higher resolution.
Weapons are now picked up with the correct timing when holding the action key.
Chimera fixes a bug where the game does auto look centering based on frame rate. This would result in vehicles being difficult to handle at high frame rates.
Names now fade in/out correctly at high frame rates when staring at a player.
Scoreboard now fades in/out correctly at high frame rates.
Halo PC has a bug where equipment spawns floor(8.1n) ticks (where n = the
netgame equipment index). This bug is fixed.
Halo's default video (not including resolution) and audio settings are set to more appropriate settings for modern PCs:
| Setting | New default | Note |
|---|---|---|
| FRAMERATE | NO VSYNC | |
| SPECULAR | YES | |
| SHADOWS | YES | |
| DECALS | YES | |
| PARTICLES | HIGH | |
| TEXTURE QUALITY | HIGH | |
| HARDWARE ACCELERATION | YES | Requires dsoal |
| SOUND QUALITY | HIGH | |
| ENVIRONMENTAL AUDIO | EAX | Requires dsoal |
| SOUND VARIETY | HIGH |
The check for updates that occurs when clicking on "INTERNET" in joining or creating games is disabled.
When Halo PC crashes, it launches a program called "Watson" to attempt to report errors to a server that has not been online in years. This is a waste of time, and it presents a minor annoyance for people who are unaware that you can simply remove the Watson folder. Therefore, Chimera removes the functionality altogether.
Servers with Chimera's chimera_allow_all_passengers, multi-team vehicles, or some equivalent feature enabled will not desync a client with this fix.
Chimera will automatically attempt to download maps off of the
HAC2 Map repo upon joining a server that
is playing a map you don't have. A different map source can be configured using
the download_template setting. These maps are stored under chimera/maps in
your Halo profiles folder by default (see the download_map_path setting).
Lua scripting ported from Chimera -572. Scripts in the global folder are loaded on startup. They remain permanently loaded unless the user uses the scripts reload command. Scripts in the map folder is loaded when a map is loaded and unloaded when a map is unloaded. Scripts may also be contained inside of map files.
Chimera has a very customizable chimera.ini text file that you can use to further tweak your game.
Note that .ini comments start with a ; and some features are commented out
(disabled) like so: ;enabled=1. This is so if you want to enable a feature,
you simply have to remove the semicolon.
Below are the features you can take advantage of.
These features exist to modify how Halo is initialized.
path (changes the profile path location)map_path (changes the path maps will be loaded from)download_map_path (changes the path custom maps are downloaded to)exec (changes the init text file loaded)server_port (set the default server port)client_port (set the default client port)console (enable console)main_menu_music (disables the music in the main menu)background_playback (allow Halo to play in the background)multiple_instances (allow Halo to spawn in multiple instances)hash (set a custom hash or % for a random one)This exists to manipulate the scoreboard
font (change the font)fade_time (change the fade in and fade out time)This exists to manipulate the names shown when looking at players.
font (change the font)This feature exists to allow you to take advantage larger amounts of RAM, reducing hiccups and stutters, especially on slower storage. However, you will need an LAA-patched executable to use this feature.
enabled (enables loading maps directly into RAM)map_size (size of buffer in MiB for loading maps)benchmark (shows a benchmark whenever a map is loaded)download_font (change the font used for downloading)download_template (URL template used to downloading maps)download_retail_maps (allow downloading of retail Halo PC maps - UNSAFE)load_embedded_lua (enables loading Lua scripts embedded into map files)This allows you to override fonts Chimera uses with system fonts, allowing you to choose the size, family, drop shadow, and weight (boldness) of each font. See the included chimera.ini for more information on these. You can also optionally add a fonts folder to your game install location to use loose ttf, otf, and ttc files.
These settings allow you to change Halo's video settings without requiring vidmode. You can even use refresh rates in excess of 120 Hz.
enabled (enables the feature)width (default width in pixels)height (default height in pixels)refresh_rate (refresh rate in Hertz)vsync (enable double buffer vSync to reduce tearing)windowed (display Halo in a window)borderless (display Halo in borderless fullscreen - required windowed mode)These settings allow you to configure gamepads. See the included chimera.ini file for more information on these settings. You can also get [premade configs] in the Chimera repository if you want to use a premade configuration file.
This allows you to customize the different colors, positioning, and timings of Chimera's chat. When we said it was a custom chat, we meant it. See the included chimera.ini file for more information on these settings.
This allows you to execute Chimera commands, Halo commands, or Halo scripts when the key combination is invoked. See the included chimera.ini file for more information on these settings.
Chimera can enable Halo Custom Edition map support when playing the base Halo PC game.
To enable this, put the following files to your maps folder:
custom_bitmaps.map (Halo Custom Edition bitmaps.map file)custom_loc.map (Halo Custom Edition loc.map file)custom_sounds.map (Halo Custom Edition sounds.map file)You can obtain these files from the Halo Custom Edition installer. Then, simply
rename them to have the custom_ prefixes and copy them into your maps folder.
NOTE: If you do not wish to install Halo Custom Edition, you can extract these resource map files from the installer using archiver programs such as 7-Zip (Windows) or p7zip (POSIX).
CAUTION: Do NOT overwrite your original bitmaps.map or sounds.map files. You need these to load Halo PC maps. Also, Chimera will not enable this feature if any of the above files are missing.
Chimera provides a number of extra features that can be turned on. Most of these features are off by default. Commands are stored in preferences.txt in the chimera folder created by Chimera.
Halo's aim assist was broken in the PC release. Chimera fixes it. It only works for analog sticks, though.
Usage: chimera_aim_assist [true/false]
Disable teammate restrictions for vehicles, allowing anyone to enter anyone's vehicle. This will only apply if you're hosting a game, and clients will need to have a version of Chimera that fixes desyncing with multi-team vehicles (or an equivalent mod), or else desyncing will occur.
Usage: chimera_allow_all_passengers [true/false]
This enables the same thing that is done in config.txt but without having to edit it. Note that this only applies to the level geometry, not individual objects. You'd need AF enabled externally to do that.
Usage: chimera_af [true/false]
When on the ground, the game disabled crouching if the player was running at full speed. You can re-enable this behavior if you want.
Usage: chimera_auto_uncrouch [true/false]
This feature runs the following commands:
chimera_block_buffering 1chimera_block_gametype_indicator 1chimera_block_gametype_rules 1chimera_block_hold_f1 1chimera_block_loading_screen 1chimera_block_zoom_blur 1chimera_block_mouse_acceleration 1Usage: chimera_block_all_bullshit
Set whether or not auto centering in vehicles is disabled.
Usage: chimera_block_auto_center [true/false]
This feature is known to reduce input lag, and it works like the feature in config.txt. Disabling buffering is known to destroy performance on DXVK, but generally works better everywhere else. You can enable this behavior if you want.
Usage: chimera_block_buffering [true/false]
Remove the quotation marks in button prompts (e.g. Hold "E")
Usage: chimera_block_button_quotes [true/false]
Netgame equipment rotation was added in Halo PC. You can disable it if you want spawns to look more like their Xbox counterparts, though most maps will probably look worse.
Usage: chimera_block_equipment_rotation [true/false]
Block your currently held weapon if you have more than two weapons. Unblock weapons with Unblock all extra weapons. This will last until the next game.
Usage: chimera_block_extra_weapon
The original Xbox version of the game didn't have the gametype indicator, and it looks out of place in most custom maps. You can disable it, if you want.
Usage: chimera_block_gametype_indicator [true/false]
In Halo Custom Edition, if you join a server, you see the gametype rules for a few seconds (or part of a second depending on frame rate). If this is annoying, you can disable it.
Usage: chimera_block_gametype_rules [true/false]
When you join a server, you'll see a "Hold F1 for score" (or whatever button is bound to score screens). You can disable this if you want.
Usage: chimera_block_hold_f1 [true/false]
Cutscenes have a letterbox. You can disable it if you want.
Usage: chimera_block_letterbox [true/false]
When you join a server, you are blinded for a few seconds by a loading screen, and this can make you susceptible to being cheaply killed. This disables that loading screen.
Usage: chimera_block_loading_screen [true/false]
Halo uses raw input, thus it bypasses the mouse acceleration setting of your operating system (unless you run the game in Wine). However, Halo adds its own mouse acceleration on top of direct input.
Usage: chimera_block_mouse_acceleration [true/false]
This hides the server IP from view in the score screen. This is good for streamers who don't want people to join what server they are in. You can enable this feature if you want.
Usage: chimera_block_server_ip [true/false]
Halo's zoom blur looks like ass on high resolutions. This feature removes it without requiring you to use DisableAlphaRenderTargets or safe mode.
Usage: chimera_block_zoom_blur [true/false]
Add a server to the server bookmarks list. If no server details are given, then the last server joined is added. You can use a domain name in place of an IP.
Usage: chimera_bookmark_add [ip:port [password]]
Delete a server from the server bookmarks list. Either an index or an ip:port can be used. If no server details are given, then the last server joined is deleted.
Usage: chimera_bookmark_delete [ip:port | index]
Connect to a server in the bookmarks list.
Usage: chimera_bookmark_connect <index>
List and query all bookmarked servers.
Usage: chimera_bookmark_list
Connect to a server in the recent server list.
Usage: chimera_history_connect <index>
List and query all recent servers.
Usage: chimera_history_list
Show the different budgets in Halo, including object limit and BSP polygon limit.
Usage: chimera_budget [true/false]
Block IPs from being shown in the custom chat. This is good for streamers, so their IPs don't get shown on stream. It requires custom chat to be enabled.
Usage: chimera_chat_block_ips [true/false]
Block all messages from the server except for if you're using rcon in the
console.
Usage: chimera_chat_block_server_messages [true/false]
Show fancy chat colors you can use.
Usage: chimera_chat_color_help [true/false]
Set the console input color.
Usage: chimera_console_prompt_color [<red> <green> <blue>]
Set deadzones for analog input.
Usage: chimera_deadzones [0-1]
Automatically delete empty weapons when hosting, similar to Xbox behavior.
Usage: chimera_delete_empty_weapons [true/false]
Enable devmode commands without blocking you from multiplayer or requiring any command line arguments.
Usage: chimera_devmode [true/false]
Set the diagonals for moving with an analog stick. This is because Halo converts it to digital input, as the netcode does not support analog movement. A good value is 0.75.
Usage: chimera_diagonals [0-1]
Set FoV. End with "v" to lock to a vertical FoV, or use "auto" to set to an automatic FoV. Using a vertical FoV over a horizontal one helps prevent the game from distorting your field of view when switching aspect ratios.
Setting chimera_fov_cinematic and chimera_fov_vehicle will apply their FoV
when those apply, falling back to chimera_fov if they aren't set or not doing
anything at all if chimera_fov is not set.
Usage: chimera_fov [degrees]
Usage: chimera_fov_cinematic [degrees]
Usage: chimera_fov_vehicle [degrees]
Set whether or not first person sounds should have reverberations when EAX is enabled.
Usage: chimera_fp_reverb [true/false]
Chimera is localized for both English and, thanks to help from the community, Spanish.
Usage: chimera_language [en/es]
Change the model detail. Higher values increase LODs. This will not make models extra detailed. Instead, it will change the threshold for when higher LODs appear. Extremely high values will cause the aforementioned "4K headless chief" glitch, except at any vertical resolution this time.
Usage: chimera_model_detail [detail]
Set the mouse sensitivity. This is more granular than using Halo's settings. It is recommended to have mouse acceleration disabled if using low values.
| Halo | Horizontal | Vertical |
|---|---|---|
| 10 | 4 | 2 |
| 9 | 4 | 2 |
| 8 | 3 | 1.5 |
| 7 | 2 | 1 |
| 6 | 1.5 | 0.75 |
| 5 | 1.25 | 0.625 |
| 4 | 1 | 0.5 |
| 3 | 0.75 | 0.375 |
| 2 | 0.5 | 0.25 |
| 1 | 0.25 | 0.125 |
Usage: chimera_mouse_sensitivity [off | <horizontal> <vertical>]
Show player info for the given player.
Usage: chimera_player_info <player>
List player indices.
Usage: chimera_player_list
Send a chat message. Channel 0 is "all", channel 1 is "team", and channel 2 is "vehicle". Other channels may be used by mods.
Usage: chimera_send_chat_message <channel> <message>
Set your in-game color for free-for-all gametypes.
Usage: chimera_set_color [color]
Set your in-game name.
Usage: chimera_set_name [name]
Show your in-game coordinates.
Usage: chimera_show_coordinates [true/false]
Show your in-game FPS.
Usage: chimera_show_fps [true/false]
Make empty weapons appear smaller so they're easier to spot.
Usage: chimera_shrink_empty_weapons [true/false]
Set whether or not to automatically reattempt connecting if the server is full.
Usage: chimera_spam_to_join [true/false]
Override the HUD with the split screen HUD.
Usage: chimera_split_screen_hud [true/false]
Spectate a specific player. Use 0 to disable spectating.
Usage: chimera_spectate <index>
Spectate the next player. This is intended to be used with hotkeys.
Usage: chimera_spectate_next
Spectate the previous player. This is intended to be used with hotkeys.
Usage: chimera_spectate_back
Set whether or not chimera_spectate_next or chimera_spectate_previous selects players not on the same team. This has no effect on non-team games.
Usage: chimera_spectate_team_only <enabled>
Teleport you or, if you're hosting a server, someone else to the given X/Y/Z coordinates or player.
Usage: chimera_teleport [#] <<#> | <x> <y> <z>>
Throttle Halo's frame rate. Set to 0 to disable.
Usage: chimera_throttle_fps [FPS]
Set the game's tick rate. This will not work outside of client hosted games.
Usage: chimera_tps [TPS]
Unblock all weapons blocked with Block extra weapon
Usage: chimera_unblock_all_extra_weapons
Uncap the cinematic frame rate from 30 FPS.
Usage: chimera_uncap_cinematic [true/false]
Fix the scaling of HUD, menu, and text elements for wider aspect ratios. This may break some maps, and this will not be fixed as fixing one thing will break another thing due to the nature of these fixes. Setting 1 has the HUD fill the screen, while setting 2 restricts the HUD to the center 4:3 area of the screen.
Usage: chimera_widescreen_fix [0/1/2]
Below is a list of frequently asked questions. These questions are either based on questions I have received or questions I might receive that I feel are worth answering in a readme.
Short answer: If your PC is semi-recent and uses Windows 10, it'll work. Note that, while Chimera isn't too taxing, especially on modern systems, it can make Halo harder to run if you're on extremely ancient hardware.
Long answer: There are the requirements:
If your PC does not at least meet the above requirements, Chimera may fail to run properly due to the underlying API being older.
There are the recommendations for running Chimera optimally:
* Halo, even with Chimera, is 32-bit, so it won't technically use more than 4 GiB, but 8 GiB is recommended so Chimera has enough RAM.
The newest of the above recommendations is the AMD CPU (FX 6100) which was released in the year 2011 - over seven years ago at the time of writing this sentence.
Probably not. You would first need to ask all of the developers of Chimera for permission.
This can occur when a required DirectX 9 library isn't installed. The fix is to download and run the official DirectX installer from https://www.microsoft.com/en-us/download/details.aspx?id=35 .
Short answer: Halo's gamma setting was disabled as it does a lot more harm than good. Basically, it's screwed up and there's no good way to fix it. This may seem like an inconvenience, but you really do not want to use this. We recommend using dgVoodoo2 for this, instead.
Long answer: How Halo's gamma setting works is, rather than changing Halo's own brightness level, it changes your operating system's brightness. It then stores the gamma setting by editing the registry. Halo is then programmed to restore the operating system's older gamma setting when it closes. However, this can only occur if Halo closes correctly. There is the chance that it won't close properly (exception errors, you closed it improperly, etc.), and if that happens, you may end up with Halo's gamma setting lingering.
We decided to disable this setting since it presented unnecessary modifications to the registry, it potentially ends up actually screwing up your operating system's video settings, and there is quite simply a better way to do it, anyway.
We are not going to provide an option to re-enable it. Again, use dgVoodoo2, instead.
Short answer: Auto updating is not actually a feature you want. For the best experience, the responsibility for keeping Chimera up-to-date falls upon you, the user.
Long answer: The gains of adding an auto updater are vastly outweighed by the cons of having one.
The only reason to add an auto updater is for convenience. Chimera is very easy to install and update. So, it is not necessary to add one even for novice users. Updates are generally announced on both the Discord server as well as on Open Carnage at https://opencarnage.net/index.php?/topic/6916-chimera-10-beta/.
In fact, there are many reasons against having an auto updater built into the mod.
First, you need write access to the mod DLL. Chimera is written to be a single strings.dll. When the game is running, this file cannot be written to due to it being in use. This can be worked around by having Chimera, itself, be a separate DLL, but this would require rewriting how Chimera is loaded. We decided to use one DLL because a number of users ran into issues with it due to user error.
Also, most people do not have write access to the Halo: Combat Evolved game files as they installed it into the default "Program Files" folder. To bypass this, you would have to manually give yourself permission (too complicated for some users to figure out), or you run the .exe as an administrator (very foolish to do on an Internet-connected game from 2003 that more-or-less assumes that cache files are "safe").
Having an auto updater or even an update notifier would also require contacting a server whenever the game starts. Doing that increases startup time, and it is error prone.
For example, an auto updater presents a security risk. You're assuming that the server used to host the update is never going to be hijacked. Signing the update can be used to mitigate this, preventing unauthorized builds from being installed due to validation failing on the client side, but that's only effective if the signing mechanism is not compromised. Also, there's the chance that a developer could decide to go rogue and deliberately push a bad update out of spite. We would NEVER do that, but should you still take the chance?
Also, existing auto updater implementations in Halo mods have all proven to cause issues, some of which are actively killing the game.
For example, SAPP, a popular server mod, has auto updating. However, some versions would crash Halo with an exception error when run on Wine. The reason for the crash is due to how the mod developer obfuscates the DLL. Wine has issues loading these DLLs, requiring them to be unpacked. However, because the DLL has been tampered with, doing this is not possible without reverting the DLL manually.
As another example, HAC2, a popular client mod, also has auto updating. Periodically, the HAC2 server may go down, and for whatever reason, HAC2 was written to not allow the user to start the game with HAC2 if auto updating failed, resulting in the player base permanently being decimated. This behavior is not unlike "always online" DRM although the intentions are not malicious - it is merely an oversight (albeit an expensive one). In fact, HAC2's loader.dll does not even come with HAC2 and requires an initial connection to the Internet to work.
Newer versions of the HAC2 loader do not exhibit this issue, but many people use the older version of the loader as it's what's most distributed. Either way, the damage is done.
Also, at some point, the HAC2 project changed developers, and updates became closed source (the public HAC2 repository is not maintained and is years out of date, and it isn't even complete enough to build). This meant that people updated from a mostly free and open source build to a nonfree and closed source build.
No mod developer should be able to do any of the following:
Also, no user should have the option to consent to any of the above, because absolutely nothing good comes from having it enabled.
Since it's easy to keep your version of Chimera up-to-date, anyway, it was decided against implementing auto updating functionality in Chimera.
Short answer: This is probably due to a CRC32 mismatch. Basically, this is to prevent Halo from crashing due to using a map that differs from what is hosted on the server. This is done for your protection, and we recommend either forging the CRC32 or getting the original map.
Long answer: Halo Custom Edition (and Chimera if joining Custom Edition servers) calculates a checksum (a number) from your map based on the contents of the map file. It then sends this number to the server upon joining, and the server compares it against the map it has. If the checksum isn't forged, then it can confirm, with ~99.999999976% certainty (or a 1 in 4,294,967,296 chance for a collision), that the map is identical.
The reason it does all of this is due to the fact that using a modified map or a different map entirely can result in a game crash for the client. Obviously, there are some modifications that can be done to a map that will not result in a crash, but there is no way to discern such a chance using a checksum, alone. This is done for your protection, and it is not recommended to attempt to bypass this check.
If you want to join a server using a modified Halo Custom Edition map on a Halo Custom Edition server, then you should forge the CRC32.
To compile Chimera we use the 32-bit MinGW-w64 toolchain.
NOTE: Versions of GCC 11.5.0/12.X and above produce builds of chimera that crash when a large amount of maps are installed. Until it is known why, the recommended way to build Chimera is on Windows with the supplied toolchain links.
The most simple way to compile Chimera on windows is using the standalone MinGW toolchain provided by Winlibs. A current version of Python is also required to be installed before following these steps.
C:\source\chimeramingw32 directory to where Chimera's source is located.build directory where Chimera's source is located.mingw-console.bat where Chimera's source is located with the following contents:
@echo off
set PATH=%~dp0mingw32\bin;%PATH%
cd build
cmd /kmingw-console.bat. A console window should open with the correct paths configured to build Chimera. To create a Release build, Run the following commands in the MinGW console window.
cmake.exe .. -G "Ninja" -DCMAKE_BUILD_TYPE=Release
ninja.exe
strip.exe strings.dllFor the correct DLL version information to be set Git for Windows must be installed, but this is not required to compile Chimera.
Compiling Chimera with Windows XP support is mostly the same as normal, however a patched version of winpthread is needed when using the above toolchain.
mingw32 with those provided by the patch.-DCHIMERA_WINXP=ON to enable Windows XP support.Chimera can be cross-compiled from a Linux host.
i686-w64-mingw32-cmake <path to source>
Because of the mentioned issues with GCC versions 12.X and higher, it may be easier to compile from a Windows environment.
