#9983 new defect

Build error with clang on 32 bit Windows

Reported by: Christoph Reiter Owned by:

Version: git-master Keywords: vulkan
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no

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.

Component: undetermined → avutil
Keywords: vulkan added
Version: unspecified → git-master

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.

Someone proposed a fix on the ML: https://ffmpeg.org/pipermail/ffmpeg-devel/2023-March/307142.html
