Re: [PLUG] "command not found" errors with different distro. 32-bit vs 64-bit?

[Pat Barron <pat@lectroid.com>]

I just did a quick experiment with Ubuntu 12.04 LTS amd64 (as I don't 
have Mint handy).

When I started (from a fresh install), there was no /lib/ld-linux.so on 
my system.  I did "apt-get install ia32-libs".  After this finished, I 
then had a "/lib/ld-linux.so.2".  I then did "dpkg -S 
/lib/ld-linux.so.2", and it told me that it was from the package 
"libc6:i386".

I think you will need to install at least that package (and any of it's 
dependencies) to make this work.  After that, I would suspect "ldd" 
would at least work, and then you can chase down whatever other 
libraries are missing, if you don't want to take the full "ia32-libs" 
package.

Thinking about it more, the "file not found" error is making more sense 
(though it's still misleading), in that the file that is not found is 
the 32-bit dynamic linker....
