    Probably module missing some dependencies.

    P.S. Where can I evaluate the newest version of Linux in FPGA? I've found some old archives of ucLinux in Altera Wiki, but it would be great to get new files. Also where can I get tools for cross-compilations?

    Maybe the problem is, that I am using GCC version: gcc version 4.4.4 20100726 (Red Hat 4.4.4-13) (GCC)

    As desribed in: http://www.alterawiki.com/wiki/install_nios_ii_linux

    there need to use GCC-4.2 ??

    You don't use the GCC on your system to build linux, but the one in toolchain-mmu. Unless you are trying to build the toolchain, it doesn't matter what you have installed.

    It does not helping :( I am getting this same error..maybe there is some problem in toolchain-mmu because to compile nios2-linux-20100621 I am using old binary nios2gcc-20080203. I was unable to compile my own toolchain of 20100621 version..

    Oh, I remember now where I've seen that error before. Did you modify nios.h or the generated custom_fpga.h ? (I don't know if these actually exist anymore in 20100621 with device tree and all)

    If you have a# define commented out C++ style // in any of those headers, it'll get into the linker script and you'll get that error.
