This helps a great deal, Triffid.
This is starting to make sense. One thing I don't quite understand: can
I use the glibc I built for the cross compilation toolchain for the one
that ends up in the root file system on my ts7200? Or do I have to build
another one? Is it just an issue of size? 20MB seems quite reasonable to
me, as I've got a 512M CF to work from.
Were you able to use Gentoo's crossdev to build your toolchain? I spent
half a day before giving up. I could not find a combination of
components that would build all the way. I left off at
crossdev -t arm --b 2.17 --g 4.1.1 --k 2.6.17 --l 2.2
which successfully built binutils, gcc but failed to build glibc (I had
worked my way down to 2.2 through a sequence of time-consuming failures
before giving up). If you succeeded with crossdev, what command set worked?
Thanks for the help.
