m64py error on Slackware64 with multilib installed.
 

I am in the process of upgrading my mupen64plus over at SBo.org to 2.0. Everything is done and it works fine, however I decided to try the m64py GUI package that was already submitted. Everything works fine on 32-bit but on 64 with multilib installed I get this error

Traceback (most recent call last):

self._handle = _dlopen(self._name, mode)
OSError: /usr/lib/libSDL-1.2.so.0.11.3: wrong ELF class: ELFCLASS32

Obviously the 32bit library is being picked up instead of the 64 in /usr/lib64. Is this something that needs to fixed at compile time or can it be fixed after the package is installed. I am not the maintainer of the m64py package, but I am just looking for an answer so I can give him a heads up.

Hello,

Have you tried to change LDFLAGS as explained here in slackbuilds's FAQ ?

It's a python build, not C or C++. So in this instance that would not apply.
