Linux development environment

Does anyone know if the Nios II port of uClinux is available as a simple tarball (i.e. tar.gz or .tgz) that can be downloaded to a Linux machine and configured and built using the nios2-elf-gcc cross...

Thanks for all your advice. I'm moving forward, but I'm still running into problems with converting the file to a flat binary.

I have used the Rules.mak file as a reference. It is located at "altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.application_0.1.0/templates" on my Windows machine.

I have also tried using the elf2flt.ld linker script located at "com.microtronix.nios2linux.application_0.1.0/scripts".

No matter what I try, I keep getting an error from nios2-elf-elf2flt that states "cpuload.elf: Input file contains no relocation info".

However, if I perform a "nios2-elf-objdump -f cpuload.elf", then I get the following results:

cpuload.elf: file format elf32-littlenios2

architecture: nios2, flags 0x00000011:

HAS_RELOC, HAS_SYMS

start address 0x00000000

Doesn't the output from objdump indicate that the elf image does indeed have relocation information?

Did I compile elf2flt improperly on my Linux machine?

Any other suggestions?
