Fixing Darwinbuild for 10.6 PowerPC and Xcode 3.2

[barracuda156]

I want to build Darwinbuild for 10.6 PPC (10A190). Do anyone of developers have an idea what that would require and whether it is feasible in principle?
As of now it fails around here for me:

UPD. darwinbuild itself does build for ppc on 10.6.8 Rosetta, however it fails to compile for ppc. Modifying plists is not enough, something overrides those settings.

[bhuntsman]

Can you try not building the MacPorts version?

[barracuda156]

@bhuntsman In principle yes, though it won’t help anyone beyond myself, and I would like to fix the build in Macports.

However, it does not hurt to try building it outside of Macports, as long as I can use Macports tools. Building everything from scratch is also doable, but then I need a clear step-wise recipe, since I only know well how to develop in Macports environment.

[bhuntsman]

This is not MacPorts, and that sounds like it could be a problem in their environment, not with our code.

To build DarwinBuild, you should just be able to git clone it, cd into the directory, and then run

sudo xcodebuild install DSTROOT=/

You can do that from a regular Terminal window. You don't need anything from MacPorts to make it work.

[barracuda156]

@bhuntsman I will try it, sure.

UPD. Ok, I tried, and it is broken. To begin with, it tries to build for wrong archs, and that fails, to no surprise.

Given that we have 10.6.8 on PowerPC natively now, I will give this another go. It’s the time to fix this finally :)

@glebm Just in case, have you looked into darwinbuild?

[glebm]

No, first time that I hear about this project!

[barracuda156]

@glebm We finally got internet working on 10.6.8 (UDP still broken, but DNS working over TCP now), so this became relevant to rebuild OS and toolchain components with ppc slices where those are missing.
(Using it for 10a190 was less needed to begin with, and more problematic, since we do not really have much sources for that build, while for releases of 10.6 there are a lot.)

What I wanna do now is replace useless SVN links leading to nowhere with macos-powerpc.org/darwinbuild and upload sources there, add ppc into plists where needed and see if something starts working. Cross-compiling from 10.6.8 on x86_64 will likely be easier than building natively on 10.6.8 ppc, since on the latter we do not have a complete toolchain yet (Xcode 3.2.6 lacks ppc slices in a lot of tools, so those will need to be rebuilt from sources).
