Question

我在clear lubuntu上编译了ffmpeg，而在eclipse中将libs附加到我的项目中我遇到了一堆错误：

/usr/local/lib//libavformat.a(mov.o): In function `mov_read_sbgp':
/root/ffmpeg/libavformat/mov.c:2039: undefined reference to `av_malloc'
/usr/local/lib//libavformat.a(mov.o): In function `mov_read_dac3':
/root/ffmpeg/libavformat/mov.c:647: undefined reference to `avpriv_ac3_channel_layout_tab'
/usr/local/lib//libavformat.a(mov.o): In function `mov_read_tfhd':

/usr/local/lib//libavformat.a(mov.o): In function `mov_read_stsc':
/root/ffmpeg/libavformat/mov.c:1712: undefined reference to `av_malloc'

它只是输出的一部分。可以somoone帮助我的工作人员？我坚持到这里，谢谢。

另外，我给你一些关于ld --verbose -l avformat：
