sdl_mixer是sdl中关于音频播放的扩展库，我基于sdl_mixer写了个程序，程序试过了，是没有问题的。我在虚拟机linux下重新安装sdl_mixer，希望把它这个软件包编译成纯静态的。然后再编译我的程序，结果就出问题了。步骤如下：
1、从网下下载SDL_mixer-1.2.8.tar.tar包。
2、解压后，在SDL_mixer-1.2.8/目录下，./configure --prefix=/usr/local --enable-shared=no --enable-static=yes，然后make clean ，然后make，再然后make install。此时在/usr/local/lib目录下产生了该软件包的静态库。
/usr/local/lib # ls
directfb-1.0-0 libdirect.a libdirect.la libfusion.a libiconv.la libSDL_image.la libSDL_mixer.a preloadable_libiconv.so libcharset.a libdirectfb.a libfreetype.a libfusion.la libSDL.a libSDL.la libSDL_mixer.la libcharset.la libdirectfb.la libfreetype.la libiconv.a libSDL_image.a libSDLmain.a pkgconfig
3、回到我程序的主目录，编译我的程序，结果出了一堆错误：

LIBS += -L/usr/local/lib -I/usr/local/include/SDL /usr/local/lib/libSDL.a /usr/local/lib/libSDLmain.a /usr/local/lib/libSDL_mixer.a
把这句改成：
LIBS += -L/usr/local/lib -I/usr/local/include/SDL /usr/local/lib/libSDL_mixer.a /usr/local/lib/libSDL.a /usr/local/lib/libSDLmain.a
把这句改成：
