在linux下编译x264时出错

Question

嘿大家 我正在尝试在linux（x64）下编译x264。但它一直给我一个错误。我用谷歌搜索了一下但一无所获。这是命令行历史记录：

spin@around:~/x264$ git clone git://git.videolan.org/x264.git

spin@around:~/x264/x264$ ./configure
Found no assembler
Minimum version is yasm-0.7.0
If you really want to compile without asm, configure with --disable-asm.
spin@around:~/x264/x264$ ./configure --disable-asm

System:     LINUX

You can run 'make' or 'make fprofiled' now.

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，仅当将 -msse 传递给 gcc 时才存在。向上游报告错误。
