Qt make出现 *** multiple target patterns. Stop.

出现这个问题的原因是使用make命令的时候，系统变量path所指定的路径有包含

其他make，如cygwin。此时要么去掉这些路径（当想要用make编译QT源文件生成执行文件

时），要么参考如下网址。

When building Qt using MinGW I get the following error: Makefile.Debug:24691: *** multiple target patterns. What can be wrong?

You probably have some include and lib paths that are not necessary and are causing problems, if you do:

1. set INCLUDE=    
2. set LIB=    
3. configure -redo    
4. mingw32-make

that should solve the problem for you.

Also, make sure that sh.exe (usually comes with Cygwin or msys) is not in the
PATH either, as MinGW’s make tool expects UNIX-makefiles when it is.
