本文解决了一个关于libvpx库编译时出现的relocation R_X86_64_PC32 against symbol `vp8_bilinear_filters_x86_8' 的错误。通过配置选项 --enable-pic --enable-static --enable-shared 和使用 yasm 作为汇编器，并且针对目标平台进行调整，最终成功解决了问题。

/usr/bin/ld: libs/libvpx/libvpx.a(subpixel_mmx.asm.o): relocation R_X86_64_PC32 against symbol `vp8_bilinear_filters_x86_8' can not be used when making a shared object; recompile with -fPIC

错误提示如上：

解决办法：

./configure --enable-pic --enable-static --enable-shared --as=yasm --target=generic-gnu

再次编译: make clean

make

搞定

参考：

Adding --target=generic-gnu to the configure line "fixes" the problem, 
suggesting that this another problem with the relocation code in the 
assembly.

--disable-mmx --disable-sse2 is also enough to "fix" the problem, but 
perhaps this is just a side-effect of the broken thing (whatever it is) 
not having an optimized version for sse, sse3 and the rest.
