./configure --enable-shared編譯想264報錯Found no assembler

Minimum version is nasm-2.13 處理方式如下

Linux下編譯x264 If you really want to compile without asm, configure with --disable-asm 的解決辦法下載 nasmhttps://www.nasm.us/pub/nasm/releasebuilds/2.13.03/解壓tar -zxvf nasm-2.13.03.tar.gz進入目錄cd nasm-2.13.03安裝即可./configuremakemake install安裝nasm之后再進入x264目錄 ./configure
