解决：libtool: line 815: X--tag=CXX: command not found

下面这个错误据说是libtool版本问题，需要回退版本，但实际上不用回退版本也可以解决，在libtool（ 请注意不是/usr/bin/libtool，而是和configure同一目录下的，在mooon中，就是src目录）文件中找到下列行：

# An echo program that protects backslashes.

ECHO="printf %s\\n"

将ECHO一句换成：echo="echo"，问题即可得到解决，如果没有ECHO="printf %s\\n"一行，但有ECHO="echo"一行，那解决方法是相同的。

$ make
