Bug 879149 – media-libs/shaderc-2022.2-r1 doesn't compile with glslang-1.3.231 (error: cannot convert ‘<brace-enclosed initializer list>’ to ‘int’)

• Product: Gentoo Linux
• Status: RESOLVED FIXED

build log

When setting the vulcan use flag and installing new dependencies for media-video/mpv, media-libs/shaderc fails to compile.

So far I've tried:

Compiling with gcc 10 and gcc 11 when gcc 12 failed.

Emerging media-libs/shaderc-2022.2 instead of media-libs/shaderc-2022.2-r1

recompiling dev-util/glslang, according to bug #840773

Unsetting the abi_x86_32 use flag.


The error is always the same as it appears in the build log:

Sets TBuiltInResource which changed and also broke ABI in the process, see [1]. Believe [2] is trying to improve the situation for upstreams but meanwhile may need to downgrade to stable ~glslang-1.3.224

    profiles: mask =dev-util/glslang-1.3.231
    
    Hopefully only masking this (rather than whole 1.3.231 stack)
    is okay. Preemptively masking myself given the ABI breakage
    will worsen the situation if left alone too long.

    profiles: extend glslang mask to whole stack
    
    Noticed the =glslang-${PV} deps so I don't see this working out.
    Hoipefully not forgetting anything.

wrt https://github.com/google/shaderc/issues/1274, sounds fixed in 2022.3

Albeit unsure what to think about the ABI breakage which is primary reason I did the mask (e.g. waifu2x-ncnn-vulkan is broken until ncnn is rebuilt, mpv[vulkan] is broken probably until libplacebo is rebuilt, albeit libplacebo fails to build with this version right now due to missing libOSDependent.a and others). Downgrade itself is messy given won't get automated rebuilds.

Maybe will need a subslot on glslang.
