Use 32-bit library on 64-bit system

[milasudril]

When running GZDoom.exe (I guess every OpenGL app) I get the error
libGL.so.1: wrong ELF-class ELFCLASS64

This is expected because it uses /usr/lib/libGL.so.302.17 which is a 64-bit binary.

I guess it would work if I could make wine use /usr/lib32/libGL.so whcih reffers to a 32-bit binary. But how?

$ uname -a

$ wine --version
wine-1.4

$ file /bin-win32/GZDoom/gzdoom.exe

Are you using the Ubuntu Wine package, or did you compile Wine yourself?

The Wine version is the one that came with the distro. However the NVIDIA driver was downloaded from NVIDIAs web site.

Try the latest package. The older Ubuntu 12.04 ones had problems.

The develop branch 1.5.x?

[dimesio]

Yes.

[milasudril]

Yes.

It doesn't work either.

The problem is solved by first setting LD_LIBRARY_PATH=/usr/lib32/

I do not think this is related to the ubuntu 12.04 topic. It is just a matter of choosing correct libraries: For a 32-bit executable, the 32-bit library is needed.

It is definitely a part of Ubuntu's multiarch problems. https://bugs.launchpad.net/ubuntu/+sour ... bug/944321
