Sorry, that statement was not correct (you posted the commands). What Imeant was that you didn't tell how you constructed these commands.

The best way is to use fltk-config but in this case it doesn't helpbecause fltk-config doesn't "know" the GLEW lib. Sorry for the confusion.

So, if you used fltk-config you should have used it like this to get therequired command switches:


$ fltk-config --use-gl --cxxflags
$ fltk-config --use-gl --ldflags

Then, add -lGLEW to the linker flags, and build your command line.

Here's a short and working form which you could simply copy:

$ g++ -o OpenGL3test `fltk-config --use-gl --cxxflags` OpenGL3test.cxx`fltk-config --use-gl --ldflags` -lGLEW
