I have spent the last day updating Mesa. No new features, just reconstructing the project. The last time it was rebuilt was in 2000\/2001, I think; required upgrades in the interim were done automatically whenever Xcode offered.<\/p>\n
But a lot has degraded in the project since automatic upgrades started. I lost the ability to debug at some point after MacOS X 10.4; with my normal development style, this isn’t a great loss, but when moving to Intel support it was trying, to say the least.<\/p>\n
It’s going to take some time to complete the rebuild. As well as getting back debugging, which I need to complete Excel import\/export support, I’ve taken the opportunity to add in gcc 4.0 updates, and to take action to remove some of the additional warning that this shows up. I will also be updating to include new recommendations for placement of support files, etc – back when we made the decisions we did, we were following the same general practices as everyone else, and there were no specific guidelines from Apple.<\/p>\n
As has already been well documented elsewhere, Zero link (ZERO_LINK) makes many projects break, Mesa included. The project inspector in Xcode ignores your Zero link settings; the only way I have found to reliably remove it is to edit the project.pbxproj file inside your xcodeproj wrapper; there seem to be two occurences for each target.<\/p>\n
One thing that has made rebuilding more of a trial than it need be was localisation. For non-localiased files, you can drag and drop from project to project, from Finder, or use the Project->Add to Project menu option; but localised files have to be manually reconstructed. There is no reason that they couldn’t be dragged between projects, at least.<\/p>\n
I will take advantage of the rebuild to generate a final build for old OS releases, probably targetting 10.2; after this point we will start to consider taking advantage of 10.4 unique features. So there will be a 10.2\/10.3 release, PPC only, and a forward going version that will initially be 10.3 PPC\/Intel, eventually moving to 10.4 only.<\/p>\n
If I notice any thing else, I’ll be sure to point it out.<\/p>\n","protected":false},"excerpt":{"rendered":"
