生成錯誤在編譯在Cygwin FFMPEG與libx264

Question

配置的ffmpeg（0.6.1）具有低於命令（X264-快照20101228-2245快照） 用gcc版本：GCC（GCC）4.3.4 20090804（釋放）

./configure --enable-shared --disable-static --enable-pthreads --enable-libx264 
--enable-gpl --disable-doc --enable-memalign-hack 
--extra-ldflags="-L/usr/local/lib" 

之後，「make」命令給出下面的錯誤。

我檢查了很多顯示相同錯誤但未提供解決方案的鏈接。任何人有任何線索已經在cygwin上構建ffmpeg？

這是在FFmpeg GIT中使用av_前綴爲bswap宏的fixed宏。你應該更新到最新的git HEAD。
