Hi,
I have been trying ,rather unsuccessfully, to cross compile the linux kernel 2.6-test3 using the compiler inside the NUE 1.2.

I get the following errors using gcc version 2.96-ia64-000717 snap 001117)

arch/ia64/scripts/check-gas-asm.S: Assembler messages:
arch/ia64/scripts/check-gas-asm.S:1: Error: Expected ':' arch/ia64/scripts/check-gas-asm.S:1: Error: Rest of line ignored. First ignored character is `:'. arch/ia64/scripts/check-gas-asm.S:2: Error: backw. ref to unknown label "1:", 0 assumed.
ia64-hp-linux-objdump: /tmp/out17472.o: No such file or directory arch/ia64/scripts/check-gas: [: !=: unary operator expected arch/ia64/Makefile:41: *** Sorry, your compiler is too old. GCC v2.96 is known to generate bad code.. Stop

so I tried the following:
Replaced the gcc with 3.0.1 & binutils with 2.11. The binutils still gave problems, replaced them with 2.14. This took care of the assembler problem and gcc warning, but the kernel compile fails at arch/ia64/kernel/signal.c

My guess that 3.0.1 may not be the correct version for compiling 2.6. I have also tried to compile 2.95.3 (as suggested in the README) for ia64, but it seem that 2.95.3 does not support ia64 configuration. Any pointers/references to solve this?

thanks

the complete build output is as below:

please upgrade to a newer version (it is safe to use this
linker, but
the kernel will be bigger than strictly necessary).

I have been trying ,rather unsuccessfully, to cross compile the linux kernel 2.6-test3 using the compiler inside the NUE 1.2.

NUE was useful when IPF hardware was hard to get, but that hasn't been a problem for a long time. As a result, NUE hasn't been updated in a while, and has obsolete versions of tools.

Quoted 2 lines

I get the following errors using gcc version 2.96-ia64-000717 snap 001117)

The 2.96-ia64-000717 release is ancient history now. It shouldn't be used anymore.

Quoted 2 lines

Replaced the gcc with 3.0.1 & binutils with 2.11. The binutils still gave problems, replaced them with 2.14. This took care of the assembler

gcc-3.0.1 and binutils-2.11 are also both old tool versions. binutils-2.14 is the latest release and should be OK. Gcc is at 3.3.1 now, but 3.2 is probably also usable.

Quoted 4 lines

My guess that 3.0.1 may not be the correct version for compiling 2.6. I have also tried to compile 2.95.3 (as suggested in the README) for ia64, but it seem that 2.95.3 does not support ia64 configuration. Any pointers/references to solve this?

The IA-64 port was written after gcc-2.95 was released. Anyone recommending gcc-2.95 for IA-64 is confused.

Hi,
I have been trying ,rather unsuccessfully, to cross compile the linux kernel 2.6-test3 using the compiler inside the NUE 1.2.

As Jim said, NUE is very old. I have had good results using the procedure described here:

http://www.gelato.unsw.edu.au/IA64wiki/CrossCompilation

You might also try distcc <distcc.samba.org>. Cross compiling is quite slow; distcc makes it more pleasant.
