Emdebian Crush on Sparc32
Dear all,
Following some very interesting conversations I had with the
Emdebian developers during the FOSDEM 2009 meeting, I would like to give
a shot at using Crush on a Sparc 32-bit architecture.
I've already been informed that the Sparc port is currently disabled and
will probably fail to build, but I'm willing to give it a try and see
if I can identify any problems.
I started today with downloading the tools on a Debian Lenny i386 host
pc.
Running emsetup -s -v produces the following messages:
---------------------------------------------------------------------
Checking apt cache data is up to date ...
Checking unstable on sparc using apt sources
Updating apt-cache for sparc
Dry run only.
Cannot find a native gcc for sparc.
Trying to locate latest version of gcc for i386.
Unable to find a suitable toolchain to build 'sparc' targets on 'i386'.
Please consider using emchain to build your own toolchain.
If you do not wish to use the emdebian toolchain repository or if a
toolchain for your chosen target architecture is not yet available for
your host architecture, please consider using emchain (part of
emdebian-tools) to build a cross-building toolchain that fits your
needs.
Packages required for 'sparc' on 'i386':
binutils-sparc-linux-gnu gcc-4.3-sparc-linux-gnu-base
gcc-4.3-sparc-linux-gnu cpp-4.3-sparc-linux-gnu g++-4.3-sparc-linux-gnu
libc6-i386-cross libc6-dev-i386-cross libstdc++6-i386-cross
libstdc++6-4.3-dev-i386-cross libstdc++6-4.3-pic-i386-cross
libgcc1-i386-cross linux-libc-dev-i386-cross
Once a suitable toolchain can be installed, setup will be complete.
Use 'emsetup --report' to check just the toolchain.
---------------------------------------------------------------------
Oh well, that was expected.
Running emchain -v to build my own toolchain produces the following
messages:
---------------------------------------------------------------------

Warning: emchain cannot find a native gcc package for sparc.
emchain will try to build a toolchain from scratch using cache values

emchain: Error. Mismatch in source versions
sparc does not appear to have built version 2.18.1~cvs20080103-7 of
binutils successfully yet. Therefore it is unlikely that emchain will be
able to build a usable cross-compiler using the current upstream source
of binutils. Only version 2.18.1~cvs20080103-1 is available on sparc and
emchain is unable to proceed.
Please run emchain again when the sparc port has updated.
---------------------------------------------------------------------
So I decided to try and ignore the error with the -f flag. Here's what
I get in this case:

E: Unable to find a source package for gcc-4.3
---------------------------------------------------------------------
Now, this is a bit odd, isn't it? Apt-get source tries to download
a version of gcc-4.3 that doesn't exist anymore, and it is not the
version that is available for Sparc.
Any ideas on how I could proceed beyond this point would be very
welcome :)
And one last thing. I keep on getting this annoying warning using the
emdebian tools:
Could not open
file /home/dimitris/.apt-cross/unstable/lists/security.debian.org_dists_unstable_main_source_Sources
- open (2 No such file or directory)
Why on earth would it be looking for security updates on unstable? I
certainly don't have any such lines in my sources.list, nor does
emdebian in the emdebian.sources.list
Best regards,
Dimitris
