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: --------------------------------------------------------------------- Building toolchain in '/home/dimitris/work/other/emdebian' Options used: verbose=2 not logging output. Checking apt-cross unstable cache for sparc. Checking unstable on sparc using apt sources Updating apt-cache for sparc Warning: emchain cannot find a native gcc package for sparc. emchain will try to build a toolchain from scratch using cache values for i386. Refreshing apt-cross unstable cache for i386. 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: --------------------------------------------------------------------- Building toolchain in '/home/dimitris/work/other/emdebian' Options used: verbose=2 forcing=YES not logging output.

Done 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 -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
