To install ia32-libs on debian wheezy amd64

You can also use aptitude to install it:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo aptitude install ia32-libs

It will install all needed dependencies for ia32-libs.

It's probably late, but here is a way to fix this. Try this:

dpkg --add-architecture i386 
apt-get update
apt-get install libc6:i386 

The ia32-libs maybe have been removed in the later version. And I have no way to solve this problem.

Finally, I find I should install libc6-i386 instead of ia32-libs.

When I try to install libc6-i386, the following information is showed for me:

libc6-i386 : Depends: libc6 (= 2.13-38) but 2.17-93 is to be installed

I previously used the stable version. So I change to testing version, and install libc6-i386 again successful.

Now I solved this problem and can run 32 bit application, although I don't know why I need a package in testing version to install package(libc6-i386) in stable version.
