Boost does not build with Xcode 4.3

[arne.schmitz@…]

With Xcode 4.3, Apple changed it's layout of the SDKs. The folder /Developer does not exist anymore. Instead everything is contained withing the Xcode.app: /Applications/Xcode.app/Contents/Developer is the new starting point. However, the darwin.jam file also globs at the wrong position. The new SDKs for Xcode 4.3.1 are at /Applications/Xcode.app/Contents/Developer/Platforms/*/Developer/SDKs/*.sdk

build fix for xcode 4.3

[arne.schmitz@…]

I have whipped up a small patch that fixes the build problems with Xcode 4.3. This is meant as a quick fix. It breaks building on Xcode < 4.3, so someone else should merge it with the old darwin.jam file.

I propose that bjam uses "xcode-select -print-path" to find out which Xcode version the user has selected as default. It then decides if the version resides in /Developer (Xcode <= 4.2) or in /Applications/Xcode.app (Xcode >= 4.3) and behaves accordingly.

This fix seems to work well, how do we get it integrated into a release? The TicketWorkflow here... ​https://svn.boost.org/trac/boost/wiki/TicketWorkflow recommends setting the owner to the component owner, who is vladimir_prus I don't seem to be able to do that, but maybe the submitter can?

Have you tried 1.50.0 or (even better) one of the 1.51.0 betas?

Wondering because they build fine for me (with Xcode 4.4, and no /Developer folder.)

[David Brittain <boost@…>]

I upgraded to 1.50.0 today, and I am using Xcode 4.4. Are you building for iOS? That's when this problem shows, regular MacOSX builds are fine without this patch.

[Marshall Clow]

Ah. That would explain why I'm not seeing the problem.

Thanks for the explanation.

[David Brittain <boost@…>]

The bug title should be updated too, so that it is clear this is an iOS issue (and that it affects xcode >=4.3)
