Hi,
I believe you use the toolchain found on uclinux.org, right? Either the
prebuilt one or you built it from source.
Well, it doesn't work with C++, simple as that. A hello world in C++ will
produce the relocation error you describe.
But the solution is simple; use the CodeSourcery toolchain for ColdFire. The
'Lite' version is free, see www.codesourcery.com
With small tweaks to the 20070130 distro, you can also compile the kernel
with it. I have described the steps in earlier threads, you might want to
search for those in the mailing list archives.
Cheers,
Harry
