The linux machines are in the last row of the lab.
Login using Novell password.
Open up a terminal (bottom toolbar icons)
Download Sample Application[links below] to a new directory [might need to use 'Save Link As' on browser]
On the terminal, type 'make' to build the application(for C++ only)
On the terminal type './jdraw' to run the application.

Instructions are the same, but you might need to customize the Makefile, to properly point to include files and libraries.
You must download and build fltk.
If you use shared(dynamic) libraries(files ending in .so), you must define the environment variable LD_LIBRARY_PATH. For instance
LD_LIBRARY_PATH = /usr/local/lib:
assumes your libraries are under /usr/local/lib

You can use the MinGW package (www.mingw.org) to get the compiler (g++) and related tools.
You will need to set your command path to include
C:\mingw\bin
You can download fltk and build it.
Build the sample application (may need to modify the Makefile to point to the location of fltk include files and libraries.

OpenGL-FLTK Drawing Application[C++]
Sources:[Main.cpp] [mainWindow.cpp] [mainWindow.h] [glWidget.cpp] [glWidget.h] [Makefile]
Entire App[sample_app.zip]
Compile C++ sources
make
Run the application as
./jdraw
OpenGL+Swing Example[Java] Using Java OpenGL(JOGL)
- Sources:[mainWindow.java] [glWidget.java]
- Compile java sources (using javac)
  javac *.java
- Run the application as
  java mainWindow
- JOGL Tutorial [PDF]
Instructions for building/running JOGL Applications:
- Download and install JOGL
- set Java CLASSPATH to include jogl.jar and gluegen-rt.jar located in the lib subdirectory. For example mine is as follows(on Unix):
  CLASSPATH=.:/usr/local/jogl110/lib/jogl.jar:/usr/local/jogl110/lib /gluegen-rt.jar
- The shared libraries(.so or .dll) in the JOGL lib/ subdirectory need to be in a known place(on your system path).
