场景

    将服务程序从SUSE迁移到CentOS,编译出错

make[1]: Entering directory `/root/rpmbuild/BUILD/test/conf'

In file included from /usr/include/features.h:385,

                 from /usr/include/stdint.h:26,

                 from ../include/MyTypes.h:4,

                 from conf_init.c:1:

/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory

make[1]: *** [conf_init32.o] Error 1

make[1]: Leaving directory `/root/rpmbuild/BUILD/test/conf'

make: *** [all] Error 1


解决

1 从SUSE上拷贝gnu/stubs-32.h到相应的目录

2.其他解决思路

说明如下：conf_init.c:第一行引用../include/MyTypes.h头文件，

而这个头文件在第四行引用/usr/include/stdint.h头文件，

而这个头文件在第26行引用/usr/include/features.h头文件，

而这个头文件在第385行应用了/usr/include/gnu/stubs.h头文件，

而这个头文件在第7行引用了gnu/stubs-32.h头文件


下面是/usr/include/gnu/stubs.h文件的内容如下：


/* This file selects the right generated file of `__stub_FUNCTION' macros

   based on the architecture being compiled for.  */



#include


#if __WORDSIZE == 32

# include

#elif __WORDSIZE == 64

# include

#els

# error "unexpected value for __WORDSIZE macro"

#endif

~       

注明：这个文件说明了64位或者32位编译环境选择的头文件。所以在编译的过程中，

使用了-m2的参数就会链接到32位版本的编译器，修改所有的Makefile文件，查看

是否有什么32位编译的删除即可。


查阅的外文资料几乎没有任何用处：

On Ubuntu it's called libc6-dev-i386 - do sudo apt-get install libc6-dev-i386. See below for extra instructions for Ubuntu 12.04.


On Red Hat distros, the package name is glibc-devel.i686 (Thanks to David Gardner's comment)


On CentOS 5.8, the package name is glibc-devel.i386 (Thanks to JimKleck's comment)


On CentOS 6.3, the package name is glibc-devel.i686.


On SLES it's called glibc-devel-32bit - do zypper in glibc-devel-32bit

在SLES系统上，执行上述指令安装，在/usr/include/gnu目录下确实生成了上述的文件。

在CentOS系统上，无效。
