Bug 120076 – have catalyst automatically setup a cross-compiling environment

• Status: RESOLVED FIXED
• Product: Gentoo Hosted Projects

[Description Andrew Gaffney (RETIRED) 2006-01-23 10:19:48 UTC]

I came up with a very easy method for seamless cross-compiling with distcc. It's described in <http://www.gentoo.org/doc/en/cross-compiling-distcc.xml>. I've put together a patch to automatically perform these steps when the user wants to use distcc with catalyst.

automatically sets up cross-distcc-fu

This is against catalyst-2.0_rc20, but the changes are localized so easy to put into any version.

new patch that uses single quotes instead of double quotes to create the wrapper

I'm currently running an amd64 stage1 build with this patch. It is distributing properly to the sparc.

new (hopefully) working patch

When I switched to single quotes in the last patch, it killed the ${CHOST} substitution when writing out the wrapper script. This should fix that.

slightly different approach to wrapper script

I just finished a stage 1, 2, and 3 build using this final patch.

Got any ideas on how to make this work on CHOST=i[3456]86-* stuff?  I have no problem adding this, but don't want to introduce any new bugs/problems with it.

[Comment 6 Andrew Gaffney (RETIRED) 2006-02-01 13:50:12 UTC]

Well, that only works if someone puts 'export CC=cc' in their envscript, and even then some builds don't work with it. The method is already broken to begin with.

The proper way to do this is to build a i586-pc-linux-gnu "cross-compiler" on a i686-pc-linux-gnu box or just create symlinks in the proper place.

[Comment 7 Chris Gianelloni (RETIRED) 2007-04-20 18:05:31 UTC]

OK.  I (finally) have a clue and have looked at this.  It looks good except for the cleanup.  We don't want to just remove everything.  Instead, we should be restoring it to its previous state, so we can still have a distcc package if this were a LiveCD.

patch

This updates the patch to put /usr/lib/distcc/bin/ back to the way it was before we touch it, instead of just clearing it all together.

[Comment 9 Chris Gianelloni (RETIRED) 2007-10-11 23:39:23 UTC]

OK.  This is in SVN now and will show up in 2.0.5_pre4 or later.

[Comment 10 Chris Gianelloni (RETIRED) 2007-10-12 00:08:12 UTC]

This should be fixed in 2.0.5_pre4.  Please test this version of catalyst (or newer) and report back if it does not work.

Thanks
