Ok, this what I tried now, since the shared library linked to by your
program is different, I made a sym link. Now it runs, but a new error
comes up:

and run the demo again, now I get this error

------------------------------

btw, would it not be better to have those prebuild demo examples in the
distribution demo/ folder be build as static instead of shared? so
that to eliminate the shared library being different on each system.

I am no expert on this, but something to consider.

That is why I was trying to build the demo files myself. But
due to that texture error, can't run them.

thanks.
