如何在64位RHEL上编译32位应用程序？ [英] How to Compile 32-bit Apps on 64-bit RHEL?

问题描述

我试图使用gcc 4.8在RHEL 7 64位上编译32位C应用程序。我得到一个编译器错误 /usr/include/gnu/stubs.h:7:27：error：gnu / stubs-32.h：没有这样的文件或目录 。我需要做什么来获得32位应用程序的编译和链接？

解决方案

要让RHEL 7 64位编译gcc 4.8 32位程序，你需要做两件事。

1. 确保所有的32位gcc 4.8开发工具完全安装：
   
   pre $ sudo yum install glibc-devel.i686 libgcc.i686 libstdc ++ devel.i686 ncurses-devel.i686
   




2. 使用-m32标志编译程序
   
   

     gcc pgm.c -m32 -o pgm

I'm trying to compile a 32-bit C application on RHEL 7 64-bit using gcc 4.8. I'm getting a compiler error /usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory. What do I need to do to get 32 bit apps compiled and linked?

解决方案

To get RHEL 7 64-bit to compile gcc 4.8 32-bit programs, you'll need to do two things.

1. Make sure all the 32-bit gcc 4.8 development tools are completely installed:

   sudo yum install glibc-devel.i686 libgcc.i686 libstdc++-devel.i686 ncurses-devel.i686
   

2. Compile programs using the -m32 flag

   gcc pgm.c -m32 -o pgm
