在我的机器上编译libfaac的时候 出现问题了 输出如下

../libfaac/.libs/libfaac.a(frame.o):frame.c:(.text+0x1e7): undefined reference to `MaxBitrate‘

../libfaac/.libs/libfaac.a(filtbank.o):filtbank.c:(.text+0x74e): undefined reference to `ffti‘

这个是因为原文漏掉一步 原文直接

./configure --host=i686-w64-mingw32 --prefix=/home/haibindev/opensdk --enable-static --disable-shared --with-mp4v2=no

实际上需要在libfaac的目录先运行./bootstrap

这时候如果提示有什么东西没有发现的话 就用sudo apt-get install 安装一下，然后make clean 

接着运行上面的configure就能正常 make了
