Cross Compile Success!

[Ian Duggan <ian@ianduggan.net>]

Yes!

I got a cross-compile tool chain and a working gnumach and hurd from it. I was even able to install over the running hurd using an NFS mount from the Hurd to my compilation machine. That will make updates fairly easy.

These instructions were pretty much dead on, though I did them on Linux rather than FreeBSD. If we want to update the Crosscompile-HOWTO, then these instructions are an ideal candidate. That will bring it out of the "out of date" status. Thanks Farid!

	http://lists.debian.org/debian-hurd-0012/msg00062.html

I used:

	binutils-2.11.90.0.5
	gcc-2.95.4 (gcc-20010408)
	glibc-2.2.2
	mig (CVS)
	gnumach (CVS)
	hurd (CVS)

A couple of things I noticed were that I had to play with the ordering of the "finish building cross gcc" and "finish build of cross-glibc" steps since gcc needed a

	./i586-pc-gnu/include/bits/stdio_lim.h

file, and that seemed to come from glibc during the "finish glibc" step. Additionally, I had to apply the patches attached to the end of this email to get it all to compile correctly. I found then around the web in various places.

Lastly, I wrapped up Farid's instructions into a bunch of different scripts and setup a framework that will allow me to quickly update any of the sources and rebuild things. I will improve it steadily. If anyone is interested, I can share it with them.

My next project is to tackle X on Hurd. Any pointers? Has anyone tried 4.0.3 yet, or is 4.0.1 still the most recent success?
