I found out, it's not relevant to sanitizers

[AndreyMlashkin]

@SpaceIm @prince-chrismc @MartinDelille @madebr @blackliner @sh0

[SSE4]

can you post config.log?

[AndreyMlashkin]

config.log

sure, here we go

[SSE4]

I found out, it's not relevant to sanitizers

it seems like it is, there are a lot of undefined references to the __asan** functions (from libmp3lame at least). perhaps, you need to propagate sanitizer libraries (or linker flags) to the ldflags?

[AndreyMlashkin]

config.log

sorry, that was output with sanitizers, here is the one without them.

I have assigned 'fsanitize' to CFLAGS, CXXFLAGS, LDFLAGS in the previous log

[AndreyMlashkin]

Important addition: I had the following flags: ffmpeg:with_libfdk_aac=False ffmpeg:with_ssl=False

[Mibu287]

I have the same problem. Then I changed libcxx to libstdc++11 compiler.libcxx=libstdc++11 and it worked.

I'm not really understand why it worked? Can anyone explain for me, please. Thanks.

[WangZhongDian]

我遇到了同样的问题，仍然无法解决

[uilianries]

@WangZhongDian Could you please give more details, like the command line used, full Conan profile, and O.S. ?

[uilianries]

Hello all! Unfortunately, I can not reproduce the described bug and the issue lacks information. The issue description says Clang 12, but the Profile points Clang 13.

I can build ffmpeg/4.4.4 using Conan 1.64.1 and following the same shared profile from this issue.

$ conan create . 4.4.4@ -pr:b=default -pr:h clang13 -o "*:shared=False" -o vulkan-loader:shared=True -s build_type=Debug

Full build log: ffmpeg-4.4.4-clang13.log

Please, update your local copy of ffmpeg and try to build it again.
