Building das Uboot for Nios2 - linker not found on Linux environment

I am trying to build Uboot for Nios2. I notice Uboot has made many changes in their build configuration.

Much of the old information for Uboot/Nios2 idid not work for me after I cloned the Uboot git repo. For example,

'boards.cfg' is no longer supported. Uboot is migrating to Kconfig for build management and there are both

Kconfig files and Make files -complicating debug.

I do the following on Linux bash.

> git clone git://git.denx.de/u-boot-nios.git

> cd u-boot-nios/

> make menuconfig

These proceeding steps complete with no visible errors or warnings.

After git clone - I can browse the Uboot source tree.

I create a minimal '.config' file.

> make all

This step fails with the following error

LD arch/nios2/cpu/built-in.o

/bin/sh: nios2-elf-ld.bfd: command not found

scripts/Makefile.build:354: recipe for target 'arch/nios2/cpu/built-in.o' failed

make[1]: *** [arch/nios2/cpu/built-in.o] Error 127

Makefile:1037: recipe for target 'arch/nios2/cpu' failed

make: *** [arch/nios2/cpu] Error 2

I tested to confirm that both 'nios2-elf-gcc' and 'nios2-elf-ld' are in the path and are executable.

It appears the compile completed (based on the message output), but the nios2 linker ('nios2-elf-ld') is not found.

I have been running Nios2 successfully on Linux.

Anyone else seen this error or found a workaround?

Dave

    I have not run Uboot on nios2. The build failed - no linker.

    I have been running nios2 on the same hardware with the

    same sopc file. And I have not previously built Uboot for this system.

    To solve the problem of not finding the linker - I needed to set the CROSS_COMPILE environment variable

    using these bash commands.

    > CROSS_COMPILE=nios2-elf-

    > export CROSS_COMPILE

    Then run make and the build completed with no errors.

    Now, I need to try to load and test on my nios2 hardware.

    THIS WAS documented in the README file starting at line 4929. So I deserve a

    "RTFM idiot". BTW, the README file has 6515 lines.
