Xcode 2.4.1, a minor update to Xcode 2.4, is available for download on 
the Apple Developer Connection.  Excerpts from the Release Notes are 
included below.  This update is recommended for people using Dwarf for 
debugging, for people developing 64-bit software for Tiger, and for 
people who have filed specific bugs against Xcode 2.4 that have been 
returned to them in Verify/Software Changed as fixed in 2.4.1.

The download includes the October documentation set.

Xcode 2.4.1 Release Notes

Xcode 2.4.1 is a minor update that fixes some known problems in Xcode 
2.4.

There are two improvements in this version of Xcode:

    New build settings that let you determine the OS and Xcode version 
and native build machine architecture at build time

    A new version of the CHUD tools

The remainder of the changes are bug fixes in the compiler, assembler, 
linker, debugger, and SDKs. Most of the fixes have to do with 64-bit 
code generation and Dwarf debugging.  The gcc and gdb release notes 
have more detail.

New Features

Projects built in Xcode 2.4.1 now have access to several predefined 
build settings that provide information about the build environment. 
You may use these build settings to define other settings that affect 
the build (for example, to have different build folders for different 
Xcode versions) or to pass as preprocessor values for compilation or 
Info.plist preprocessing.

The new predefined build settings are:

NATIVE_ARCH_ACTUAL            The actual architecture of the build machine 
(ppc, ppc64, i386, or x86_64).
NATIVE_ARCH_32_BIT            The 32-bit version of the build machine’s 
architecture (ppc or i386).
NATIVE_ARCH_64_BIT            The 64-bit version of the build machine’s 
architecture (ppc64 or x86_64).
MAC_OS_X_VERSION_ACTUAL    The Mac OS X version as a four-digit number 
similar to MAC_OS_X_VERSION_MAX_ALLOWED, e.g. 1047.
MAC_OS_X_VERSION_MAJOR        The major version of Mac OS X, e.g. 1040.
XCODE_VERSION_ACTUAL        The Xcode version as a four-digit number; in 
this release, 0241
XCODE_VERSION_MAJOR        The major version of Xcode; in this release, 0200

You cannot set these build setting values. These values will be 
supported on future versions of Xcode, but are undefined for Xcode 2.4 
and earlier.

Bug Fixes

Xcode 2.4.1 also fixes an incompatibility introduced by Subversion 
1.4.  If you have upgraded to Subversion 1.4 on Tiger, you should 
upgrade to Xcode 2.4.1 to use integrated Subversion support.

The Finder Get Info information for Xcode 2.4.1 now agrees with the 
Xcode About box.

vecLib headers have been updated in the 10.4u SDK.

Distributed Builds now correctly disable distribution between 
incompatible versions of Mac OS X that happen to have the same version 
number.

Debugging now works correctly for functions in anonymous namespaces.

Step In to Objective-C methods now steps in, rather than continuing 
execution.

The incidence of bogus "<incomplete type>" messages when printing 
variable values has been greatly reduced.

AvailabilityMacros.h in the 10.2.8 SDK has been fixed to set the 
MAC_OS_X_VERSION_MAX_ALLOWED macro value correctly.

Problems relating to using QuickTime 7.1.2 headers with the 10.3.9 SDK 
have been resolved.  The 10.3.9 SDK now contains working QuickTime 
7.1.2 headers and stub libraries.
