Dear Ladies and gentleman,
I have installed your OpenSG in the version 1.8.0. 1. Now I want to
start running your program 01firstapp.cpp in eclipse in linux debian. So
I have startet there a new managed c++ project and have include the file
01firstapp.cpp in this project. In the compiler options I have include
the subdirectory GLUT. If I start then the cimpiling of your program I
get the following error message
**** Build of configuration Debug for project testOpenSG ****
make -k all

make: *** [firstapp.o] Fehler 1

Build complete for project testOpenSG
Please can you tell me what I have do wrong, so that the program is running.
With best wishes and thanks,
Stefan Heyer
