我想在32位系统下运行一个64位程序，在网上搜索查到了一些信息，如下：
Hi,

currently you are trying to compile maq in 64 bit (look for the -m64 in the output of make). Since you don't have a 64 bit operating system the compiler doesn't find the neccessary libraries (stubs-64.h). Try one of two ways to fix that:

1)
make clean
set the environment variable CC to "gcc -m32" (I assume gcc is your compiler,)
./configure
make

2)
make clean
edit the file Makefile.generic and look for CFLAGS; change -m64 into -m32
make -f Makefile.generic

This sets the -m32 flag and tells the compiler to build the 32 bit version.

greets,

Andreas

这个人所说的Makefile.generic文件在那里？
谢谢拉
随便再问一句，make clean是什么意思阿？
