linux下编译ffmpeg时关于configure的问题.

Question

ubuntu在编译ffmpeg包的时候需要用到之前编译的x264，
错误提示 libx264 not found.

查看了config.log,后面出现了一堆：
ratecontrol.c:(.text+0x7a33): undefined reference to `__pow_finite'
/usr/local/lib/libx264.a(ratecontrol.o): In function `x264_ratecontrol_slice_type':
ratecontrol.c:(.text+0x85ca): undefined reference to `__log2_finite'
ratecontrol.c:(.text+0x8633): undefined reference to `__log2_finite'
ratecontrol.c:(.text+0x878c): undefined reference to `__pow_finite'
ratecontrol.c:(.text+0x87e1): undefined reference to `__pow_finite'
/usr/local/lib/libx264.a(ratecontrol.o): In function `x264_ratecontrol_end':
ratecontrol.c:(.text+0x8c1f): undefined reference to `__pow_finite'
