I guess it would be easier to do the : port using netbsd as host but as the hw is not yet ready we are using an : ebsa285 board to do the prototyping and I was told that netBSD doesn't : support it natively (though I could be mistaken). The cross compilation may be a bit of a problem. while the binutitls are setup to easily build different targets, the current gcc in the tree isn't setup to do that at all. I'm working on "fixing" that for a target that I'm working on. Once that is done, the cross compiler stuff should be fairly simple and easy. Until that happens, however, your best bet may be to use gcc 2.8.1 or egcs and configure it --target arm-unknown-freebsd3.0. You'll need to write some files to support this, but configure will tell you which ones (if you clone the FreeBSD entry). : Also, some pointers as to what are the main steps for doing such a port : (FreeBSD port as a whole) would be greatly appreciated. Step one, get build tools working. Step two-a, get the kernel working Step two-b, get userland working Step three boot. For kernel breakage, see step two-a, for userland breakage, see step two-b :-) You'll need to have at least some of the kernel files in place before you can build a userland. Trying to build the user land will tell you what is missing :-). Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
