Building Cross-Compilers

[Jan-Benedict Glaw]

Hi!

I'm regaining all the fun of porting! :-D  I've just set-up again some
script to (once a day) build a (kernel-only, for now) cross-compiler
for the vax-linux target. (To be exact, I'm building for all these
targets:
	alpha-linux arm-eabi avr bfin-elf frv-linux h8300-elf
	hppa-linux hppa64-linux m32r-linux m68k-linux
	microblaze-uclinux mips-linux mips64-linux mn10300-linux
	powerpc-linux powerpc64-linux ppc-linux ppc64-linux
	s390-linux s390x-linux sh-linux sh64-linux sparc-linux
	sparc64-linux tic6x-uclinux tilepro-linux vax-linux
	xtensa-linux
)  It's the `master' branch of binutils's, gcc's and gdb's GIT
repositories.  What made me wonder the most was that things seem to
work out of the box. I remember the dark times quite well, when it was
quite a drama building a kernel-only cross-compiler, let alone one
that could build userland.

My next step is to also extract Maciej's SRPMs (you can find them at
ftp://ftp.linux-mips.org/pub/linux/mips/people/macro/SRPMS/) and build
them as well (for `vax-linux' only.)  That should bring me back to
business.

What's also quite nice is, that after not building a vax-linux gcc for
quite some time, it just worked. Some 5 or 6 years ago, that target
was broken like two times a month! That was (even longer ago) why I
wrote a script to compile a compiler on a regular basis to catch
problems early. (It's easier then to find the trouble-causing patch.)

MfG, JBG
