299213 - Mac PPC build fails, Xcode 2.1 and no SDK or deployment target set

Status: RESOLVED INVALID

(Firefox Build System :: General, defect)

Description

[Mark Mentovai]

Follow-up to bug 298529.  The system's root SDK (/usr/include, etc.) is the
10.4u SDK under Xcode 2.1.  API changes prevent it from working, and foreclose a
clean workaround in code or preprocessor conditionals.

Workaround: when Xcode 2.1 is installed, use a SDK other than the 10.4u SDK by
using --with-macos-sdk.  10.2.8, 10.3.9, and 10.4.0 are all tested and
functional.  10.2.8 is currently recommended.  If you must target the 10.4u SDK,
specify a deployment target with --enable-macos-target.

Attachment: Workaround

This is suboptimal, although the ugly code path won't be hit by production
builds for the foreseeable future.

Comment 2

[Mark Mentovai]

Apple provides the workaround in the header itself, where it belongs.  In the
10.4u SDK, the offending struct is defined non-opaque if DT < 10.4.  The 10.4.0
SDK (only bundled with the obsolete Xcode 2.0) is defective in this regard. 
This is only a problem if Xcode > 2.0 is installed over Xcode 2.0.  Workaround:
on the off chance that you've got the 10.4.0 SDK, don't use it.  It's been
superseded by 10.4u anyway.
