arch xtensa does not compile

[Jan Dittmer]

Hello Chris,

the recently merged xtensa arch does not (cross) compile successfully.
I'm using 2.6.12-git7 which seems to have all patches (1-8) merged.

It would be nice if you could fix these issues.

I did have to make some more changes because of the other changes in 
Andrew's tree, but wasn't sure what other patches would make it in.
I'll submit the Xtensa patches shortly.

Thanks for the report.

Current git tip (2.6.12-rc1-git5) still does not compile for me:

  LD      usr/built-in.o
  AS      arch/xtensa/kernel/align.o
  AS      arch/xtensa/kernel/entry.o

make[2]: *** [arch/xtensa/kernel/entry.o] Error 1
make[1]: *** [arch/xtensa/kernel] Error 2
make: *** [_all] Error 2

I guess I'm using the wrong binutils version (2.15.94.0.2.2). Which is the
recommended gcc/binutils pair which is supposed to compile the kernel?

Unfortunately, I don't think the correct configuration is currently 
checked into the binutils/gcc tree. I'll talk to Bob (he is the 
maintainer for binutils+gcc for Xtensa) when I have a chance (Monday is 
  Independence Day). It compiles fine with a local copy of binutils+gcc 
with the correct configuration.

BTW, I really like your website. Are you planing to release the script 
files?

Thanks,
~Chris

Bob Wilson made some changes to binutils last week to address this 
problem but he only submitted it to the latest binutils version.

With the latest gcc+binutils toolchain, the kernel compiles for me.
Note, however, that I just submitted a patch that is not in Linus' tree, 
yet.

gcc version 3.4.5 20050707 (prerelease)
GNU ld version 2.16.91 20050707

Thanks,
Chris

Yep, using GNU ld 20050710 and gcc 3.4.4 20050513 I get much further now.

Is the gcc version still too old? Or do I need some special config option?
