That sounds odd; it works fine for me (on an arm64 mac). However this flag isn't a great solution either, since Xcode 16, the = linker warns "ld: warning: -ld_classic is deprecated and will be removed = in a future release". > This led me to a reference indicating that YASM already does it right. > I tried to build with YASM instead.

I would recommend you to use the Apple provided Clang rather than GCC. // Martin _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
