missing separator

make的时候发现出现

Makefile:8: *** missing separator. Stop.

在http://gcc.gnu.org/ml/gcc/2001-02/msg00635.html这里看到了解决方法，实际上也很简单，就是必须要有一个tab

The problem is that that white space at the start of line 8 *must* be
a TAB character, not ordinary spaces.

Further problems with make would be better addressed to the make help
mailing list, which is at help-make@gnu.org
