Using the Nios II Command Shell

Hi PhillipD

To get rid of the IDE was the first thing I did after it was introduced. I my humble opinion it sucks. No way I could live with that as a programmer. Way too slow, very hard to document your compiler settings etc, just a plain pain.

Now I uses my favourite editor slickedit and a makefile and GNU make (3.80 remember something about problems with never versions) via CYGWIN.

I spent quite some time figuring out what to compile etc. But now this sort of makefile works nicely in several projects.

Hope it might help you too.

You will need the linker script created by the IDE too.

Makefile is below.

Regards Jacob
