sdl error

Hi,
after opening a rom in mupen64(running under suse 9.0) i get this message:
-----------------------
Gtk-WARNING **: invalid class type `(unknown)' in cast to `GtkObject'

Gtk-CRITICAL **: file gtkobject.c: line 1034 (gtk_object_set_data): assertion `GTK_IS_OBJECT (object)' failed.
-----------------------

before this it says that the rom was loaded succesfully.
then, after pressing the start emulation button, i get this:
-----------------------
[blight's SDL input plugin]: version 0.0.8-b initialized.
Initializing OpenGL Device Context
(II) Initializing SDL video subsystem...
(EE) Error initializing SDL video subsystem: No available video device
Signal number 11 caught:
errno = 0 (Success)
Xlib: unexpected async reply (sequence 0x2541)!
-----------------------


and the emulator exits..

i have tried reinstalling sdl, even compiling it from source. no change..
i have an nvidia geforce 4 mx 420. the driver is from nvidia's site..
any advice would be useful...
thanks.

i tried it now.
the configure script doesnt work:
----------------
./configure: line 1: tempfile: command not found
./configure: line 1: tempfile: command not found
./configure: line 28: : No such file or directory
*** Couldn't compile test program.
rm: cannot remove `': No such file or directory
rm: cannot remove `': No such file or directory
*** Couldn't find a working C compiler!
-----------------
but gcc is installed, i can compile other programs w/o problems...

here's the make result:

make
gcc -DX86 -O3 -fomit-frame-pointer -funroll-loops -ffast-math -mcpu=athlon -Wall -pipe -c -o main/rom.o main/rom.c
main/rom.c:37:18: zlib.h: No such file or directory
In file included from main/rom.c:43:
main/unzip.h:52:18: zlib.h: No such file or directory
In file included from main/unzip.h:56,
from main/rom.c:43:
--------
then lots of various errors follow..

well no, it seems that other gamez using sdl arent working either...
so i reinstalled sdl.. nothing.
got the sdl source compiled it.. still no changes..
