关于在64位linux下开发32位linux程序的一些问题,ubuntu,debian,opensuse

1,debian x64上支行ubuntuX64编译的32位程序 

Linux debian 4.19.0-8-amd64 #1 SMP Debian 4.19.98-1 (2020-01-26) x86_64

需要安装包

apt-get install lib32stdc++6
apt install glibc-devel.i686 glibc-devel
apt-get install lib32z1-dev

apt install libc6-dev-i386

软件包：lib32z1-dev（1:1.2.8.dfsg-2+deb8u1） [security]

compression library - 32 bit development
zlib is a library implementing the deflate compression method found in gzip and PKZIP. This package includes the development support files for building 32 bit applications.

增强
dep: lib32c-dev
本虚包由这些包填实： libc6-dev-i386
dep: lib32z1 (= 1:1.2.8.dfsg-2+deb8u1)
compression library - 32 bit runtime
dep: zlib1g-dev (= 1:1.2.8.dfsg-2+deb8u1)
压缩库 - 开发文件

有32位的环境后,在/下可以看见

 lib32,lib64的库,程序就可以运行了.

使用file ,ldd 命令查看

 可以正常加载x86的地址了.

2,opensuse

openSUSE-Update-Leap-15.1 ,x64

zyppper install glibc-devel-32bit
zypper install libstdc++-devel-32bit 
zypper install libstdc++6-32bit  

前几天在64位linux下开发跨平台的代码，包括32位和64位的版本都需要编译，在给g++加上-m32开关之后，g++报了一个错误：

gnu/stubs-32.h: No such file or directory compilation terminated. make: ***

在网上翻了一圈，情况就是64位linux缺省只安装了64位的头文件和Lib版本，需要增加32位的版本库，网上提到的安装方法一般是CentOs, Ubuntu之类的发行版，我用的是OpenSuse，最后在老外的网页上找到了一个比较全面的各个版本的安装说明：

You need 32bit embedded GNU C Library. This incldes development Libraries, header files, contains the symlinks, headers, and object files needed to compile and link programs which use the standard C library.

Fix for Debian Linux
Type the following command:
$ sudo apt-get install libc6-dev

Fix for Ubuntu Linux
Type the following command:
$ sudo apt-get install libc6-dev-i386

Fix for OpenSUSE / Novell Suse Linux (SLES)
Type the following command:
# zypper in glibc-devel-32bit

Fix for RHEL / Fedora / CentOS / Scientific Linux
Type the following command：
# yum install glibc-devel.i686

 

安装了头文件，还要注意安装库文件，方法同上，包括以下库：

gcc-32bit gcc7-32bit libstdc++6-gcc7-32bit libstdc++6-gcc7-locale libstdc++6-locale

 3,ubuntu x64上支行32位程序 

Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-142-generic x86_64)

apt-get install ia32-libs
apt-get install lib32ncurses5 ​
apt-get install lib32z1
apt-get install lib32z1-dev
apt install libc6-dev-i386

Ubuntu apt-get install ia32 for 32-bit on 64-bit
先更新 ia32的库

To install 32-bit libraries on a 64-bit linux system
Install:

  $ apt-get install ia32-libs
To install 32-bit libraries for development
Install:

  $ apt-get install lib32gcc1 libc6-i386 lib32z1 lib32stdc++6
  $ apt-get install lib32asound2 lib32ncurses5 lib32gomp1 lib32z1-dev lib32bz2-dev
  $ apt-get install g++-multilib
You may need this too, or it may be a virtual package already provided:

  $ apt-get install ia32-libs-gtk
You may need a symlink, which g++-multilib may set up for you automatically:

  $ ln -s /usr/lib32/libstdc++.so.6 /usr/lib32/libstdc++.so
Update LD_LIBRARY_PATH
You may need to add the LD path, for example like this:

  $ edit /etc/profile
  ... add these lines...
  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib32:/usr/lib32
  export LD_LIBRARY_PATH
To compile with gcc
To compile things with gcc, you need to add the flag -m32 like this:

  gcc -m32 myfile.c
