I'm attempting to follow the "getting started" article at
http://www.ucdot.org/archive/tb/tb20020807.shtml. I'm trying
to build uClinux-dist-20080808 for the xcopilot target using
toolchain binaries from m68k-uclinux-tools-20061214.tar.bz2.
None of the kernel versions will build.
2.6 Fails thusly:
[...]

AS arch/m68knommu/platform/68328/romvec.o
LD arch/m68knommu/platform/68328/built-in.o
AS arch/m68knommu/platform/68328/head-pilot.o
arch/m68knommu/platform/68328/head-pilot.S:37:23: error:

make[2]: *** [arch/m68knommu/platform/68328/head-pilot.o] Error 1

/home/grante/uclinux/uClinux-dist/linux-2.6.x'
make: *** [linux] Error 1
Indeed, there doesn't appear to be a bootlogo.rh file in the
2.6 tree (there is in the 2.4 tree).
2.4 Fails like this:
[...]
/home/grante/uclinux/uClinux-dist/linux-2.4.x/include/asm/atomic.h:70:

In this case, it appears gcc is choking on a multi-line string
literal.
And 2.0 likewise:
[...]

The 2.0 errors look an awful lot like what happens when you try
to compile source files with DOS line endings using an old
version of gcc. But, I thought the version being used (4.1.1)
no longer barfed on CR/LF line endings.
Is there different simulator target that's recommended over
xcopilot? Is there a more recent "getting started document"
somewhere? I also found http://www.uclinux.org/get_started/uClinuxbeginner.html,
but it's also 5 years old and shows the exact same steps as the
other getting started article.
