Running x86 P4V binaries on Linux x86_64

How to install the 32-bit compatibility libraries on 64-bit native Linux.

PROBLEM

How do you run P4V (a 32-bit application) on a 64-bit linux distribution on an x86_64 compatible platform?

SOLUTION

Most distributions of Linux offer 'compatibility' libraries that enable you to run 32-bit applications on top of 64-bit linux. The names of the libraries differ from distribution to distribution; this article discusses three of the more common ones. Note that these provide the 'bare-bones' compatibility needed, in some cases more libraries may be required. Check online for the FAQs related to your specific distribution.

Some distributions feature kernels with the compatibilty built right in.  

Ubuntu

64 bit Ubuntu does not install 32 bit support libraries by default. You will need to install two additional packages:

sudo aptitude install ia32-libs    
sudo aptitude install ia32-libs-gtk

CentOS / Red Hat

Both of these distributions boast compatibility through the kernel.  32-bit P4V should 'just work' on recent versions of these distributions.

If it doesn't, try the following:

yum compat-libstdc++

Gentoo

Emerge the package.

emerge emul-linux-x86-compat
