Hi All,
I'm trying to get SDL_Mixer to build into a fully working SDL-UWP (WIP) game project following the instructions as per the SDL UWP WinRT documentation here > https://hg.libsdl.org/SDL/file/tip/docs/README-winrt.md but I'm getting linker errors.

The lowdown:
1: Right clicked the solution, added existing project, selected SDL_mixer-UWP.vxcproj from SDL_mixer-6dd19d5ca940/VisualC-WinRT/UWP_VS2015.

2) On the UWP project, in the project tree > references > Add reference, ticked SDL2_mixer-UWP.

3) On the UWP project Properties > C/C++ > General > Additional Include Directories > C:\SDL2.0.4\SDL2_mixer-2.0.1\include added. Also 'Not Using Precompiled Headers' set.

Build output:
Linker error 1:
Error LNK1104 cannot open file 'C:\Users\User\documents\visual studio 2015\Projects\SDL-WinRT-DX11-UWP_v1\Debug\libogg_dynamic-UWP\libogg.lib' SDL2_mixer-UWP

I could not find libogg.lib anywhere in the SDL_mixer source, mercurial or VC_dev directories.

Linker error 2:
Error LNK1104 cannot open file 'C:\Users\User\documents\visual studio 2015\Projects\SDL-WinRT-DX11-UWP_v1\Debug\SDL_mixer-UWP\SDL2_mixer.lib'

Dropping a copy of SDL2_mixer.lib into 'C:\Users\User\documents\visual studio 2015\Projects\SDL-WinRT-DX11-UWP_v1\Debug\SDL_mixer-UWP\SDL2_mixer.lib' caused two more linker errors:

New linker error 1:
Error 0xdef00071 File C:\Users\User\documents\visual studio 2015\Projects\SDL-WinRT-DX11-UWP_v1\Debug\SDL_mixer-UWP\SDL2_mixer_UWP.pri not found.

New linker error 2:
Error 0x80070002 Processing Resources failed with error: The system cannot find the file specified.

Hopefully it's something minor. Ultimately, all I need is the ability to load compressed audio files (mp3 / ogg) for music and effects.

Thanks in advance.

There are MSVC project files for libogg, libvorbis, etc. that are in the same directory as the SDL_mixer/UWP project file. Can you try including those in your VS solution, make your UWP app's project reference them, then try rebuilding?

Can you perform a full rebuild, then send me the entire build log?

I've created a new project in VS2015 named 'SDL-WinRT-DX-test' based on the C++ DX11 template, (same as previous), and gone through the WinRT docs to step 6A and used the example main.cpp code in that so I'm getting the app to build and show a green screen.

Then I added into the solution from C:\SDL2.0.4\SDL_mixer-6dd19d5ca940 - HG - source\SDL_mixer-6dd19d5ca940\VisualC-WinRT\UWP_VS2015...
libogg_dynamic-UWP.vcxproj
libvorbis_dynamic-UWP.vcxproj
libvorbis_dynamic-UWP.vxcproj
SDL_mixer-UWP.vxc proj

Then all four above were added as references to SDL-WinRT-DX-test, along with SDL2-UWP (Already selected).

Same 3 linker errors;

I just pushed out a possible build fix for SDL_mixer, to https://hg.libsdl.org/SDL_mixer .

Can pull + update the latest SDL_mixer sources from there, and try rebuilding?

Hi David,
Using the latest SDL_Mixer source (SDL_mixer-efa81a285f22) from https://hg.libsdl.org/SDL_mixer, and the stable SDL2.0.4 source from https://www.libsdl.org/download-2.0.php, more errors I'm afraid.

I'm wondering if the fix I applied last night, which changed libvorbisfile's VS ProjectGuid, might've confused the build system on some level(s).

Can you try the following?

1. performing a Clean on the VS Solution
2. closing VS
3. manually deleting the build-output and build-intermediate directories
4. reopening the VS Solution
5. rebuilding

If you like, I can also try building on my end. If you send me a .zip of source code, optionally with game-assets and game-specific-code removed, I can give it a shot.

I tried your suggestions but to no avail. Do you think it matters that I'm developing on Win10 build 10240? (Used Winver to confirm).

Also, this is the Target and Minimum version I choose when I creating these SDL-UWP test projects.

For now I'll try some ideas out and get back to you. :-)

That should be fine. SDL and SDL_mixer's MSVC project files both set their Target and Minimum versions to Win10 build 10240.
