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! -Irfan On 3/30/07, Oleksandr Tymoshenko wrote: > On behalf of FreeBSD/MIPS team I'm proud to announce that > project has reached single-user stage.
