搞了两晚上，终于hello了\(^o^)/，先上图

简单说：

1、编译、汇编源文件

将/usr/bin/as重命名

mv /usr/bin/as/usr/bin/as_bk

新建/usr/bin/as，并输入下面这样的内容

vi /usr/bin/as

*******************************

#!/bin/sh



/usr/bin/as_bk --32 $*

*******************************

赋予执行权限

chmod 755 /usr/bin/as

然后编译cbc/test里的hello.cb

​cbc /usr/local/cbc-1.0/test/hello.cb

之后报错信息不管，只要能在/usr/lib下看到

hello.shello.o就ok

2、安装32位函数库（我的64位centos里面没有32位库）

参照http://blog.csdn.net/liushihuidfg/article/details/46442209

搜索可用的glibc软件包

[root@localhost ~]# yum search glibc
已加载插件：fastestmirror,langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.sina.cn
 * extras: mirrors.sina.cn
 * updates: mirrors.cqu.edu.cn

  名称和简介匹配 only，使用“search all”试试。
[root@localhost ~]# yum install glibc.i686

安装32位的glibc.i686

3、建立软连接

ln -sv/usr/lib/libc.so.6 libc.so

因为每次ld的时候系统默认去找libc.so，这个配置到哪里的不知道，简单点就直接软连接

4、最后一步：链接执行

还是嘴儿http://blog.csdn.net/liushihuidfg/article/details/46442209

ld -melf_i386 --dynamic-link /usr/lib/ld-linux.so.2 -lc -L /usr/lib -ohello hello.o

最后执行

​​./hello

完结撒花\(^o^)/
