ROM build errors

[Joe Holden]

Hi guys,

I am trying to build a rom with generic defaults for ALIX (although the 
same error appears regardless of mainboard/chipset combination, with the 
exception of QEMU - that doesn't even start to build at all:

make[2]: *** [out/rom16.o] Error 1

I suspect this might be related to the error I get when set to 'master' 
which looks like a binutils bug that was fixed post-packaging, My build 
machines run Slackwre 13.37.0 with binutils before the patch: 
http://sourceware.org/bugzilla/show_bug.cgi?id=12726

Can anyone confim this is actually the problem and it will go away if I 
build a more recent binutils?

Thanks,

The problem is indeed with your toolchain. I strongly recommend that
you run make crossgcc in the top level coreboot source directory,
which will then build a reference toolchain with known working
components. The toolchain should be discovered automatically by the
coreboot and SeaBIOS build systems. You can verify this by cat:ing
the .xcompile file in the root source dir.
