gcc compiler for nios2

The Nios II toolchain can be rebuilt under Linux using the source code found on the Nios II Embedded Processor CD.

The source code should be installed onto your windows machine. I tarred and bzipped it, and then transferred it to my Linux machine.

Word of warning... the toolchain is littered with CRLF's that really cause problems with the configure scripts and Makefiles. Any problems you might have are quite likely due to CRLF's. You may want to try running the source tree through a "dos2unix" type utility. I used "flip" to fix up the tree.

I used the following environment variables while following the instructions below:

target = nios2-elf
prefix = /home/kenw/work/r6200
scratch = /home/kenw/tmp
