编译安装libmad-0.15.1b"-fforce-mem"错误

cc1: error: unrecognized command line option “-fforce-mem”

 

在我编译安装audacity的时候出现下面的错误
cc1: error: unrecognized command line option “-fforce-mem”
其实这个错误是编译安装libmad时候引起的，audacity包含libmad

解决方式是：找到libmad configure之后的Makefile,

vi Makefile

找到包含"-fforce-mem"字符串，将其删除，就ok了

原因是gcc 3.4 或者更高版本，已经将其去除了，所以会出现上面的错误！

Compiling libmad with gcc 3.4 or higher will produce the following error: cc1: error: unrecognized command line option “-fforce-mem”. The build option “-fforce-mem” has been kicked out of gcc, so you need to alter the makefile (just vi Makefile after you have configured, hit “/” to search for the entry and delete it)
