Mac OS X port

[kode54]

It would be really neat if this could also be ported to Mac OS X. I'm not sure what help I could be in that effort, though.

I did some work in an attempt to move this forward, thanks to RBDOOM-3-BFG:

https://github.com/jeremiah-sypult/DOOM-3-BFG

It compiles and launches, but audio & video rendering do not work. Based on blind input control after launching, the console output appears to load the game data and run. The audio is merely stubbed out at the moment. The OpenGL rendering is incompatible on OS X mainly due to the fact that DOOM-3-BFG uses a OpenGL 3.2 compatibility profile, which is not supported at all on OS X (only the Core profile is supported). In order for it to ever run on OS X, the compatibility bits of the renderer would have to be rewritten to use core profile (including the GLSL shaders, which produce errors during compilation).

Unfortunately, the required renderer changes are outside of my programming skills...

Oh man, I don't know how to use Github. I wanted to link my pull request to this issue, but it created another one instead - #117

Works only with SDL 2 obviously.

[RobertBeckebans]

Nice I'm going to test this at the weekend.

[JanSimek]

I am not sure if I should submit a new ticket for the following error, but since no one else is complaining, it is probably OS X specific.

When taking the elevator from Mars City to Underground, game throws me back into the main menu with the following error:

idSoundSample_OpenAL::CreateOpenALBuffer: error loading data into OpenAL hardware buffer

As a temporary workaround I changed that error in AL_SoundSample.cpp into a warning and was able to play further without any problems.

[DanielGibson]

Apple's OpenAL is known to suck, you should try openal-soft: http://kcat.strangesoft.net/openal.html (but turning that into a warning still makes sense IMHO)

[kode54]

And now, with this latest commit, I get this error while attempting to compile:

[JanSimek]

Just to clarify, you were able to compile it before commit b8676a5?

[JanSimek]

OK, this happens when building with clang instead of gcc. There is no such thing as use_idStr_snPrintf or use_idStr_vsnPrintf, so removing those four lines from Str.h fixes the problem.

[DanielGibson]

I think the purpose of those lines is to tell people not to use snprintf but to use idStr::snprintf() instead (on Windows snprintf() is broken/insecure)

[JanSimek]

I added some objective-c code to replace those functions in linux_main.cpp which rely on procfs and it compiles fine with gcc, but when compiling this source file with clang I get this error:

error: Objective-C 1 was disabled in PCH file but is currently enabled

I have never seen it before and I can't google any useful info about it. Any ideas?

[DanielGibson]

PCH could be precompiled header

[ghost]

i've tried to compile it on os x 10.9.4 and got the following errors:

am i doing something wrong?

[JanSimek]

My fault. Compile it with SDL 2

[ghost]

with SDL2 it failed to compile too:

Set SDL 2 include directory in CMake to /Library/Frameworks/SDL2.framework/Headers

[ghost]

now it compiles successfully, but the game runs without sound. game log says that sound system initialzed:

----- Initializing Sound System ------ Setup OpenAL device and context... Done. OpenAL vendor: Apple Computer Inc. OpenAL renderer: Software OpenAL version: 1.1 OpenAL extensions: AL_EXT_OFFSET AL_EXT_LINEAR_DISTANCE AL_EXT_EXPONENT_DISTANCE AL_EXT_float32 AL_EXT_STATIC_BUFFER AL_EXT_SOURCE_NOTIFICATIONS sound system initialized.

see the game log here: http://pastebin.com/qWK1DsKS

[ghost]

i've compiled game with openal-soft instead of apple's openal but with no luck. game log still says that sound system initialized:

see the game log here: http://pastebin.com/6U6dVcFR

[ghost]

i launched game with "+set developer 1 +set log file 2" params, game log here: http://pastebin.com/DxysUKap

can someone tell me what is wrong with the sound? does anyone got the same problem? is there any workaround?

[ghost]

my sound issue appears only if i launch the game as a root, not by other user. seems like there is a mess with some environment variables or something.

[DanielGibson]

Why would you launch the game as root? Don't do that..

[ghost]

it's because of my old habit, nevermind. thanks to everyone who make it possible to run the game on osx and everyone on this thread.

I experience the same error on macOS which @JanSimek described above:

When taking the elevator from Mars City to Underground, game throws me back into the main menu with the following error:

idSoundSample_OpenAL::CreateOpenALBuffer: error loading data into OpenAL hardware buffer

This error still crashes the game. How do I fix that? I installed openal-soft via homebrew and even manually force-linked it. However, CMake does not seem to pick it up: -- Found OpenGL: /System/Library/Frameworks/OpenGL.framework

I also manually changed the Error into a Warning as temporary workaround, but this is not the only (but the only crashing) openal error I get.
