linux - 在 Linux 中编译 x264 时出错

Question

大家好我正在尝试在 linux (x64) 下编译 x264。但它一直给我一个错误。我用谷歌搜索但一无所获。这是命令行历史:

这是文件，从第 83 行到第 91 行:

#if HAVE_VECTOREXT && defined(__SSE__)        v4si v16 = {v,v,v,v};        M128( d+s*0+0 ) = (__m128)v16;        M128( d+s*1+0 ) = (__m128)v16;        if( h == 2 ) return;        M128( d+s*2+0 ) = (__m128)v16;        M128( d+s*3+0 ) = (__m128)v16;#else

Answer 1

v4si 是一个 SSE 标识符，它只在 -msse 传递给 gcc 时存在。向上游报告错误。
