交叉编译mpg123
下载源码https://sourceforge.net/projects/mpg123/files/
解压后进入源码目录
生成Makefile
./configure CC=arm-openwrt-linux-gcc --host=arm-openwrt-linux --with-default-audio=alsa --enable-static --prefix=pwd/install/
编译
make
安装
make install
拷贝install下的lib/libmpg123.so* lib/libmpg123.so* lib/mpg123/到板子/usr/lib下， bin/mpg123到板子/usr/bin/下。
测试
export MPG123_MODDIR=/usr/lib/mpg123
mpg123 -o alsa -a hw:0,0 test.mp3
注意：如果不执行export那步，会报错
