Hi Dirk,
thanks for the answer.
Yep, they run. But here I just found out a curious thing: If I
compile the tutorials with the provided makefile in the terminal the
05Geometry example (which basicly uses the same functions I am having
trouble with) is running. If I create a project of the 05Geometry.cpp
in xCode it compiles, but crashes with exactly the same NullFC
problem. So I was thinking that maybe I am missing some compile/link
options or a #define? Because in the last case (05Geometry under
xCode) I also had to define OSG_WITH_GLUT to make it at least
compile.
Compile is different from link is different from run. ;) Can you
compare
the actual options passed to the compiler from the Makefile to the
ones
passed by xCode? It sounds like you haven't set up some flags that are
needed.
I checked that. xCode is passing all the options that are needed as
far as I can see plus a lot of things I don't know where they come
from, but if xCode created it I believe it needs it. Unfortunateley I
don't see anything missing in the xCode options that are included in
the makefile based attempt:
This is all I need to do in the terminal, to get 05Geometry build and
running:
c++ -DOSG_WITH_GLUT -DOSG_WITH_TIF -DOSG_WITH_PNG -DOSG_WITH_GIF -I/
Users/mschwier/Projects/OpenSG/Builds/powerpc-apple-darwin-g++/
include main.cpp -L/Users/mschwier/Projects/OpenSG/Builds/powerpc-
apple-darwin-g++/lib/dbg -lOSGWindowGLUT -lOSGSystem -lOSGBase -
framework Cocoa -framework GLUT -framework OpenGL -o main
this is what xCode is doing and it compiles and links, but crashes
when running (I know it's a lot but maybe somone with more knowledge
than me about these options sees something :-/):

If nothing works out I am about to compile it via the command line
and use xCode only to write my code ... *sigh*
To all that helped me until here a big thanks!
