It would be more significant to report the output of : cygcheck -c openGL which would tell us which version of the openGL package you have. I will assume 1.1.0-8 which is the latest; if not, please upgrade to it using the setup program. > > $ g++ -O2 -mno-cygwin example1.cpp -o example1 -L/usr/lib/w32api -lglui > -lglut3 > 2 -lglu32 -lopengl32 > /usr/lib/w32api/libglui.a(glui_spinner.o):glui_spinner.cpp:(.text+0xd): > undefine > d reference to `___getreent' > ... > /usr/lib/w32api/libglui.a(glui_edittext.o):glui_edittext.cpp:(.text+0x237): > more > undefined references to `___getreent' follow> collect2: ld returned 1 exit > status > No surprise: -mno-cygwin and -L/usr/lib/w32api are incompatible > [EMAIL PROTECTED] /usr/share/doc/opengl-1.1.0/GLUIexamples/Cygwin > $ view /usr/share/doc/Cygwin/opengl-1.1.0-8.README > That file tells you how to rebuild the package from its sources. I don't think that's what you intended. To learn how to _use_ the package, please view: /usr/share/doc/opengl-1.1.0/README.txt > [EMAIL PROTECTED] /usr/share/doc/opengl-1.1.0/GLUIexamples/Cygwin > $ make> g++ -c -O2 -mno-cygwin example1.cpp > g++ -O2 -mno-cygwin example1.o -L/usr/lib/w32api -lglui -lglut32 -lglu32 -lope > ngl32 -o example1> > /usr/lib/w32api/libglui.a(glui_spinner.o):glui_spinner.cpp:(.text+0xd): > undefine > d reference to `___getreent' > ... > /usr/lib/w32api/libglui.a(glui_edittext.o):glui_edittext.cpp:(.text+0x237): > more > undefined references to `___getreent' follow > collect2: ld returned 1 exit status > make: *** [example1] Error 1 Obviously you added -L/usr/lib/w32api to the makefile. Undo all your changes to that file; if unsure reinstall the package with the setup program. Then: cd /usr/share/doc/opengl-1.1.0/GLUIexamples make clean make That will build all 6 examples for both Cygwin (executables in the Cygwin subdir) and Mingw (executables in the Mingw subdir).
