alsa  lib:

#!bin/sh
rm -rf ./output/*
mkdir -p ./output
chmod -R 777 ./output
OUTPUT_PATH=`pwd`/output

make clean
make distclean

export CROSS_COMPILER=""
export CC=${CROSS_COMPILER}gcc
export LD=${CROSS_COMPILER}ld
export AR=${CROSS_COMPILER}ar
export NM=${CROSS_COMPILER}nm
export STRIP=${CROSS_COMPILER}strip
export CFLAGS="-DPIC"
./configure --prefix=/usr --enable-shared -with-pcm-plugins=all --with-ctl-plugins=all

make
make DESTDIR=${OUTPUT_PATH} install

如果是交叉编译，需要指定CROSS_COMPILER 和host，例如：

export CROSS_COMPILER="arm-linux-gneabihf-"

./configure --prefix=/usr --host=arm-linux-gneabihf --build=x86_64 --enable-shared -with-pcm-plugins=all --with-ctl-plugins=all
