Googled for a while but drawn a blank.

Need to build 32-bit app on 64-bit Ubuntu.

Realise that I need to install ia32-libs. I have done this and apt-get tells me it's already at the latest version.

This link: http://packages.debian.org/squeeze/amd64/ia32-libs/filelist says that libstdc++ should be in /usr/lib32

It's not there!

I have uninstalled, reinstalled (with force) ia32-libs.

Any ideas? How can I get this critter on my box?

Ta, Ben

Try installing this:

apt-get install lib32stdc++6

It installs this:


One way to build 32 bit apps on 64 bit system is using a 32 bit chroot. There are some excellent notes on how to do this in this wiki: https://help.ubuntu.com/community/BasicChroot
