I'm getting a yasm related build error that I didn't hit when building ffmpeg on Windows.
I ran the following commands to build libav on a new Big Sur install after installing xcode command line tools: ``` brew install yasm brew install pkg-config ./configure --disable-everything --enable-libvpx --enable-encoder=libvpx_vp8 --enable-encoder=libvpx_vp9 --enable-muxer=webm make ``` This installed yasm 1.3.0 and pkg-config 0.29.2. And I get this error from make: ``` libavutil/x86/tx_float.asm:842: error: undefined symbol `ff_cos_32_float' (first use) libavutil/x86/tx_float.asm:842: error: (Each undefined symbol is reported only once.) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_64_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_128_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_256_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_512_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_1024_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_2048_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_4096_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_8192_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_16384_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_32768_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_65536_float' (first use) libavutil/x86/tx_float.asm:1210: error: undefined symbol `ff_cos_131072_float' (first use) make: *** [libavutil/x86/tx_float.o] Error 1 ``` This line (42) in tx_float.asm seems to provide the undefined symbol but truth be told I've never worked with a project using asm and not sure from what I've seen what the problem is. cextern cos_ %+ i %+ _float ; ff_cos_i_float... _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
