Hello all,
it seems the latest compilers on macOS require -fno-common to be set in
order to avoid a compilation error (/ld: warning: reducing alignment of
section __DATA,__common from 0x8000 //to 0x4000 because it exceeds
segment maximum alignment/).
Here is a post about the issue: https://lists.ffmpeg.org/pipermail/
ffmpeg-devel/2025-May/343169.html <https://lists.ffmpeg.org/pipermail/
ffmpeg-devel/2025-May/343169.html>
At the moment -fno-common is only set if ASAN is enabled but it should
always be set.
Hi
for now this doesn't seem to create an issue in our macOS cirrus-ci
build, but that's certainly because we doesn't use the latest macOS in
the CI job.
Let's see after 2.6.1 if there's any side effect when -fno-common is used.
