[erlang-questions] compiling R14B02 with WX support on Ubuntu 11.04

[Dan Gudmundsson]

It seems to be a Ubuntu 11.04 problem with (proprietary) drivers.

In my case /usr/lib/libGL.so is linked to mesa/libGL.so and not to
nvidia-current/libGL.so
which erlang-wx uses for dynamically loading all functions and extensions.

But wxWidgets (and SDL) loads and creates the context with
nvidia-current/libGL so
two different GL implementations are used.

Link /usr/lib/libGL.so to point to the correct nvidia-current/libGL.so
and it works.

IMHO this is a bug in (atleast) the nvidia package in ubuntu 11.04.
I googled  a bit and it seems other GL wrappers have the same problem
in 11.04, so maybe someone
should tell the ubuntu guys.
