Hi,

I use the nios2mmu branch because it deals with the custom_fpga.h file instead of the device tree (I work with Windows XP and I don't know if the sopc2dts tool works with Windows).

I created a board layer like said here in Altera Wiki (alterawiki.com/wiki/Creating_a_Nios_II_Design_with_an_MMU)

I downloaded the toolchain nios2gcc-20080203.tar.bz2

Here is my problem:

After having exported the PATH (export PATH=$PATH:~/path_to_toolchain/opt/nios2/bin), when I want to compile the kernel, the simple instruction make dosen't work. Here is the trace:

I have to add CONFIGURE_HOST=nios2-linux because, without this, the prefix needed is nios2-linux-gnu witch dosen't exists for me.

But then, I have this error :
