编译alsa-lib
if [ "$1" == "" ]; then BUILD_LIBS=${HOME}/lib-ffmpeg fi export PATH=${BUILD_LIBS}/bin:${PATH} export PKG_CONFIG_PATH=${BUILD_LIBS}/lib/pkgconfig make clean ./configure \ --prefix=${BUILD_LIBS} \ --enable-shared make make install
编译alsa-utils
if [ "$1" == "" ]; then BUILD_LIBS=${HOME}/lib-ffmpeg fi export PATH=${BUILD_LIBS}/bin:${PATH} export PKG_CONFIG_PATH=${BUILD_LIBS}/lib/pkgconfig make clean ./configure \ --prefix=${BUILD_LIBS} \ --enable-shared make make install
看到参数如下，吾没有理会，也许别人有用？
./configure \ --prefix=${BUILD_LIBS} \ --with-alsa-inc-prefix=${BUILD_LIBS}/include \ --with-alsa-prefix=${BUILD_LIBS}/lib \ --disable-alsamixer --disable-xmlto --disable-nls
