本文指导如何在Ubuntu 64位系统上安装32位库，包括基本库、开发库以及如何更新LD_LIBRARY_PATH。

Ubuntu apt-get install ia32 for 32-bit on 64-bit
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
