ZDoom with OpenAL

[Gez]

Apparently, because it doesn't compile on Windows.

Ideally, though, this would be useful. Even disregarding the potential for going GPL or double-licensing, having the possibility of choosing between OpenAL and FMOD Ex would mean that ZDoom could be ported to more platforms.

[Aroenai]

Well I got farther, I think I'm just missing a link to a library but I can't be sure. Amazing what someone can do with no programming skills while clicking on the third result of a google search...

Also, "#define" needed to be added to several of the lines and the DWORD error was mentioned elsewhere in the zdoom source, even with instructions on how to fix it.

[Gez]

Chris hasn't been around for a while...

[Aroenai]

Last visited June 27th, 2010 according to his profile, it hasn't been that long, it's just a little over a month. I said it more for reference anyway.

[Chris]

I don't think he ever tested on Windows, being a Linux user.

Anyway, take one guess why this code was never included into ZDoom officially and probably never will...

I wouldn't mind doing cross-compiles using MinGW for testing compatibility (somewhat, at least). It's not too difficult to cross-compile a CMake project, but unfortunately, building ZDoom relies on being able to run some of the programs it builds.. which, obviously, won't work when the target system is different form the host (I once tried to hack the build system so it would run those apps under Wine, but I wasn't very successful).


Aroenai, what '#define's were needed? Those latest errors look like you're missing the glib/gstreamer import libs.

On Ubuntu at least if you have Wine installed you can do ./some.exe from the terminal and Wine will run it. I've successfully cross compiled my Wolfenstein 3D port which uses a portion of ZDoom's code including zipdir.

2>.\src\sound\oalsound.cpp(1310) : error C2061: syntax error : identifier 'typeof'

What import libs am I missing still? I've already added OpenAL32.lib, gstapp-0.10.lib, gstreamer-0.10.lib, gthread-2.0.lib, gmodule-2.0.lib, gobject-2.0.lib, and glib-2.0.lib using src\CMakeLists.txt as a guide. My previous post has a patch with the changes I made attached.

2>.\src\sound\oalsound.cpp(1310) : error C2061: syntax error : identifier 'typeof'

typeof() isn't standard, though I thought MSVC supported it, so

Code: Select all

x = reinterpret_cast<typeof(x)>(alGetProcAddress("x"));

fails. Those defines you added prevent the macro expansion that's supposed to happen (I'm surprised it even compiled), which would cause problems once the EFX functions are called. I thought of another way to handle it that avoids typeof, though, so I should be able to get that fixed.

MSVC's min/max issue really annoys me.

I think I got the DWORD issue resolved.

As for the import libs, can you double-check that the libs were added to the project? The Windows side doesn't properly disable the OpenAL backend if the GStreamer libs weren't found (which I'll fix up), they just don't get added to the linker. Of course, ideally Windows would use something other than GStreamer, but I don't know what is available that would be appropriate, and that I know how to use.

On Ubuntu at least if you have Wine installed you can do ./some.exe from the terminal and Wine will run it. I've successfully cross compiled my Wolfenstein 3D port which uses a portion of ZDoom's code including zipdir.

Hmm, right. Some systems set up a binfmt rule so PE executables are invoked with Wine. AFAIK, that's not recommended (partly because C# executables are also PE format and would be invoked with Wine instead of Mono), but Ubuntu isn't known for having proper system setups. Still, it is an option, I suppose.

[Aroenai]

Never mind, generated new project files with cmake and it no longer has those linker errors and they are added to the project. I must have done something wrong when I added them manually. So I guess once those other issues are fixed it will compile fine then?

[Chris]

Hopefully. How well does this patch work?

[Graf Zahl]

I'm going to create an OpenAL branch so that this can finally be managed by SVN. I hope that will make things easier for you.

[Graf Zahl]

No idea what you did here but the patch does not work. Did you create this with GZDoom? The revision number seems to suggest so. Problem is, even in that case it's worthless because I can't safely backport the changes to the CMakeLists files. In addition I can't apply it because I still get inconsistencies.

[Chris]

The changes were made with GZDoom, but I made sure the patch applied to a clean ZDoom checkout (r2528). How about this one, diffed from a modified ZDoom r2530 tree?

I don't believe I have SVN access, but a branch I could write to would be rather useful. Thanks.
