[U-Boot] Building Uboot for Nios2 - linker not found on Linux environment

[U-Boot] Building Uboot for Nios2 - linker not found on Linux environment

[Dave Williams]

I am trying to build Uboot for Nios2.

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.

> 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 but the nios2 linker is not found.  The
Nios2 binaries  - nios2-elf-gcc and nios2-elf-ld are in same path location.

I have been running Nios2 successfully on Linux.

Anyone else seen this error or found a workaround?

Sorry that the u-boot-nios.git is used for upstreaming to u-boot.git 
only, and is not always up-to-date.

Please use u-boot.git instead.

BTW. which version of nios2-elf-gcc did you use? I've tested with v3.4.6 
and v4.9.1.

Cheers,

To solve the problem of not finding the linker - I had to set the
CROSS_COMPILE
environment variable using these bash commands.

> CROSS_COMPILE=nios2-elf-
> export CROSS_COMPILE

Running make - the build completed with no errors.

THIS WAS fully documented in the README file starting at line 4929.
So I fully deserve a "RTFM idiot" comment and Kudos to the writer(s) of the
Uboot README file.
