海思平台编译libfaac
root@ubuntu:/mnt/hgfs/3520shared/Hi3516A_SDK_V1.0.3.0/faac-1.28# ./configure --host=arm-hisiv300-linux --enable-shared --prefix=$PWD/installed
root@ubuntu:/mnt/hgfs/3520shared/Hi3516A_SDK_V1.0.3.0/faac-1.28# make && make install
编译好的库放在当前目录的installed下面
最终会在指定安装目录获得如下动态及静态库:
libfaac.a
libfaac.la
libfaac.so
libfaac.so.0
libfaac.so.0.0.0
将获得的动态链接库放入开发板/usr/lib目录即可
虚拟机上编译也要加上连接选项

如果是3520,可能会提示这个错误:ambiguates old declaration 'const char* strcasestr(const char*, const char*)'
从123行开始修改此文件mpeg4ip.h,到129行结束。
修改前:
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
修改后:
#ifdef __cplusplus
extern "C++" {
#endif
const char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
如果生成库编译调用时候提示缺少
//编译出来的库拷贝到板子的/usr/lib目录下
