#9983 closed defect (fixed)

Build error with clang on 32 bit Windows

Reported by: Christoph Reiter Owned by:

Description

Looks like clang 15 got stricter somehow:

C:/msys64/home/user/M/mingw-w64-ffmpeg/src/ffmpeg-4.4.2/libavutil/hwcontext_vulkan.c:865:15: error: incompatible pointer to integer conversion assigning to
      'VkCommandPool' (aka 'unsigned long long') from 'void *' [-Wint-conversion]
    cmd->pool = NULL;

Some searching suggests that VkCommandPool is a handle, and that VK_NULL_HANDLE should be used, but I don't know enough about vulkan. It builds fine with it at least.

Please either provide the configure line you tested and clang -v output to make this a valid ticket or - much better - send your patch made with git format-patch to the FFmpeg development mailing list.

The configure line is a simple "./configure".

$ clang -v
clang version 15.0.3
Target: i686-w64-windows-gnu
Thread model: posix
InstalledDir: C:/msys64/clang32/bin

I will try to look into providing a patch. I need to read up on the vulkan API first though.

Yeah, this can be closed.

It regressed again in the meantime, but that's another issue, and I'll try to upstream that some time: https://github.com/msys2/MINGW-packages/blob/342a841670ecf0aabe3cffd3b57abf2e02945e23/mingw-w64-ffmpeg/0009-wrong-null-type.patch
