Documentation on compile-time macro -DDOOM_UNIX_INSTALL

[coreybruce]

Hello there I just wanted to ask for some help/documentation and understanding on the compile-time macro -DDOOM_UNIX_INSTALL so the binary can be a system package and will look at ~/.local/share/doom64ex-plus if the wad doesn't exist in the folder it's in or /usr/local/share/doom64ex-plus for example as I believe this should be documented on the readme when compiling on Linux.

[atsb]

It is documented:

GNU/Linux / BSD

GNU/Linux and BSD supports system installations using the compile-time macro -DDOOM_UNIX_INSTALL this will force the software to look for all IWAD and supporting files inside ~/.local/share/doom64ex-plus

compile-time macro -DDOOM_UNIX_SYSTEM_DATADIR=\"/some/system/path\" allows to specify the system folder where the software will look for all IWAD and supporting files. Packagers should set DOOM_UNIX_SYSTEM_DATADIR to a proper folder for the distro and package files doom64ex-plus.wad and doomsnd.sf2 into that folder.

Is this not clear enough?

[coreybruce]

No sorry I don't fully understand sorry which is why I was asking for a bit of clarity when it comes to compiling with a little bit more description on the building process, could you give me a example of how to do it? :smiley:

This is not completed, why was this closed?

[atsb]

I didn't close it.

[atsb]

I will add more clarity

[coreybruce]

Oh maybe I did by mistake, woops

That would be great thank you but could you also explain the process while I'm here

[coreybruce]

Hey there is there any update on the clarity of documentation? could I get a example of the building process please?

[atsb]

I do this in my spare time.. it will be done when I have time.

[atsb]

I've documented it as much as I can for non-technical users. I cannot do more than this. Compilation and packaging is intended for developers, so I've summarised and clarified as much as I am able to do.

[coreybruce]

Well I am a developer, a package maintainer and compile binaries and maintain multiple projects. I just haven't had to go beyond make, cmake or cargo and I just didn't understand what the exact argument was or how to use it,

I think it would be way easier if did this by default instead of needing to do whole separate and more complicated building options when it could just check if /usr/share/games/doom64ex-plus\ exists and if it doesn't check the folder it's running in, if a developer wanted to change the path then they can do so in the make file. with CFLAGS += -DDOOM_UNIX_SYSTEM_DATADIR=\"/usr/share/games/doom64ex-plus\"

That's my suggestion :smiley:

Also I added CFLAGS += -DDOOM_UNIX_SYSTEM_DATADIR=\"/usr/share/games/doom64ex-plus\" to the make file and put the DOOM64.WADand put the files and the game wad in the folder and tested the~/.local/share/doom64ex-plus``` folder and it couldn't find it

Z_Init: Init Zone Memory Allocator
CON_Init: Init Game Console
G_Init: Setting up game input and commands
M_LoadDefaults: Loading game configuration
I_Init: Setting up machine state.
glFinish: Called for: AMD
D_Init: Init DOOM parameters
W_Init: Init WADfiles.
Error - W_Init: IWAD not found

********* ERROR *********
W_Init: IWAD not found% 

[atsb]

I'll take a look, I don't normally use them as my main machine is a mac and I don't need it there.

[atsb]

For inside a makefile the syntax would be:

DOOM_UNIX_SYSTEM_DATADIR=/usr/share/games/doom64ex-plus

-D is only needed for bash and the shell build scripts.

[coreybruce]

Hmm ok I tried that and it still doing the same thing and it's trying to create a config in the wrong location

Z_Init: Init Zone Memory Allocator
CON_Init: Init Game Console
G_Init: Setting up game input and commands
M_LoadDefaults: Loading game configuration
Error - G_ExecuteFile: Unable to create /usr/share/games/doom64ex-plus/config.cfg
