Is it possible to install 32-bit libraries on a 64-bit system?

CamTheSaxMan · 01-11-2014, 11:47 AM

I'm trying to run a program that is only available for 32-bit Linux in a .deb package. I've already installed ia32-libs and multiarch-support, however the program requires the library libXxf86dga.so.1 which isn't included in ia32-libs. So, trying to run the program gives me the error:
error while loading shared libraries: libXxf86dga.so.1: wrong ELF class: ELFCLASS64
since it's trying to use the 64-bit version. Is it possible to install the 32-bit version of that library. Can I just download the 32-bit package and install it? Or copy the library from an existing 32-bit Ubuntu installation?

If Ubuntu works like Debian in this regard then all you have to do is append ":i386" to the name to install it. For example I had to run

Code:

apt-get install libpango:i386"

so that a particular program would run.

When I try to do that, it and says I can autoremove a whole bunch of libraries and then threatens to remove some of my programs:

I DON'T want to remove brasero, nemo, etc. so I pressed n and ran sudo apt-get autoremove, but it says:

odd...

I did...

I too have had requests for 32-bit packages as dependencies when installing something. For openSUSE, I search the the package list displayed when I open Software Management, otherwise I look on the Internet for an RPM for my SUSE version. So far there has been not one problem.

I suggest you do the same; install the needed packages after searching for them in the installed repositories for your linux version.

Installed libraries just sit there unless something calls on them. As long as you have the ones that are needed, a few extra or an extra copy of a later version doesn't make any difference.

I was able to find the source code and I just compiled the program from source and it seems to work. Thanks anyway, though.

Probably the best course of action. It's possible that Ubuntu does multilib a little differently to its parent (wouldn't be the only thing) and I realised that the error you posted suggests that the .deb you had wasn't set up for multilib so I'm not sure whether it would work anyhow though I don't know enough of the details to know.
