What toolchain for vr4181

What toolchain for vr4181

[Jørg Ulrich Hansen]

Hi

I am about to start porting Linux to my hardware with an vr4181 processor.
The hardware is very close to the osprey architecture. Now my problem is
what toolchain to use.
I could do with an up to date opinion.

? gcc-2.95.3
? gcc-2.95.4
? egcs-1.1.2
? gcc-3.2
? binutils 2.13
? glibc 2.2.5
? Any patches
? http://www.ltc.com/~brad/mips/mips-cross-toolchain/index.html
? http://kegel.com/crosstool/

Where is a good starting point for a toolchain that will build and work?
I would prefere to build it my self because at a later state I might build
it under cygwin. But a prebuild does also have interest.

Kind regards Jorg

At work we use plain binutils 2.13.2.1 and gcc 3.2.2, which we build ourselves
(host is Solaris/SPARC).

Joined trees? Which configury? Unfortunately, toolchain questions are
quite FAQs, but there doesn't really exist _that_ good HOWTOs which
actually contain exactly helpful hints (eg. which versions and/or which
additional patches are needed).

If companies have some kind of scripts or the like they use, I'd really
love to see them published. That'd really help all those guys out
there:)

Binutils (binutils-2.13.2.1.tar.bz2):
    configure --target=mips-linux --prefix=/wherever/you/want

Gcc (gcc-core-3.2.2.tar.bz2):
    configure --target=mips-linux --prefix=/wherever/you/want --enable-languages=c --enable-shared --with-gnu-as --with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-included-gettext

I took the development libraries and includes from Debian:
    libc6-dev_2.2.5-11.2_mips.deb
    libc6_2.2.5-11.2_mips.deb
    zlib1g-dev_1%3a1.1.4-1_mips.deb
    zlib1g_1%3a1.1.4-1_mips.deb

I wrote very simple Perl clones of dpkg and dpkg-deb with just enough
functionality to get `dpkg-cross -i' working on Solaris. I don't know whether I
can share them, though.

It took me a while, but here they are, wrapped as a Christmas gift! :-)

You also have to take /usr/bin/dpkg-cross from a Debian system and probably
want to hardcode crossbase=/wherever/you/want, unless you're root.

BTW, I'd still really like to have some scripts so I can install (from binary
or from sources) Debian binaries in my home dir on a Red Hat or Solaris box.
Wishful thinking?

Well, 'dpkg-deb -x' does the unpacking, which should be enough for most
of the simple packages. But I can't just come up with a "general"
solution except...

Hmmm. Maybe you can use debootstrap for this purpose.
