This is very likely to cause out of memory errors. This will probably work better: gcj -c -O -fjni --classpath=x1.jar x2.jar gcj -c -O -fjni --classpath=x1.jar x3.jar gcj -c -O -fjni --classpath=x1.jar x4.jar And link them all together at the end. > So, this was fine compiling on Windows using a Native Cross Compiler > provided by Mohan Embar on a 32 bit processor.

I use emacs, but it's a steep learning curve. I understand that Eclipse works OK with gcc.
