I'm building the newlib toolchain on Ubuntu 13.10 32 bit. I built the first set of tools without problem, but when I build newlib and gdb without or1ksim (http://opencores.org/or1k/Toolchain#Newlib_toolchain_.28or1k-elf.29) and run the make command, I have a problem:

/bin/bash: or1k-elf-cc: command not found

The string "or1k-elf-cc: command not found" happens everywhere and a lot of .a files couldn't be found. I googled but I can't find any working solution yet.

Did you remember to export PATH=$PATH:/path/to/or1k/bin

I can't find that folder. Which step of the building progress created it?

I meant, did you remember to add the path where you installed your toolchain to
to your PATH environment variable.

Thank you, I misunderstood your previous answer. My problem is now solved.

Did you install the tool chains from https://openrisc.io/newlib/ or using sudo apt-get install?
