使用mpeg4的音频编码器为何出错阿

cgl520cn

首先安装faac编码器
但是在编译连接时出错阿

#include <unistd.h>
int main(void)
{
   unsigned long *samples;
   unsigned long *size;
  faacEncHandle handle;
  faacEncConfigurationPtr config;
  handle = faacEncOpen(44100,2,samples,size);
  if (handle == NULL) {
    return -1;
}
  config = faacEncGetCurrentConfiguration(handle);
  faacEncSetConfiguration(handle, config);
  return 0;
}

gcc test.c -g -o test -lfaac

/usr/local/lib/libfaac.so: undefined reference to `log'
/usr/local/lib/libfaac.so: undefined reference to `cos'
/usr/local/lib/libfaac.so: undefined reference to `sin'
/usr/local/lib/libfaac.so: undefined reference to `pow'
/usr/local/lib/libfaac.so: undefined reference to `log10'
/usr/local/lib/libfaac.so: undefined reference to `asin'
