Hi Gonzo, all
I plan to work on a FreeBSD R7K Mips port in Big-endian mode. The
other catch is that I want to do my development on Linux. I have
looked at the makefiles and am fairly confident that they can be
worked out with pmake on Linux (Fedora).
My real problem is how do I force the built objects/binaries into
a Big-Endian UFS file-system. I don't have a BE machine. Is it
possible, to somehow use files/dirs built on a an LE system to be
bundled into a BE UFS filesystem ? Any tools/hints.
thanks!
