Summary0014254: With Xcode-5DP $CURRENT_ARCH is set to undefined_arch and makes OBJECT libraries fail to compile
DescriptionThe following test example fails to work with the Xcode generator and Xcode 5DP-2

add_library(lib OBJECT lib.c)
add_executable(test test.c $<TARGET_OBJECTS:lib>)

The problem seems to be that CURRENT_ARCH is set to undefined_arch whatever I try to select, Xcode buildlog:

The use of CURRENT_ARCH was added here:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=8045e171 [^]

Is there an alternative for this version of Xcode?

Now that Xcode 5 is out I was able to reproduce this. While $(CURRENT_ARCH) appears to be broken in the PBXFileReference objects used to add object files to the link phase, Xcode 5 also fixes dependencies in OTHER_LDFLAGS so we can put the objects there instead.

Here is the fix:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=a3194ff4 [^]

The 3 immediate ancestors of that commit also fix other problems with Xcode 5.

If there are further issues please open a public issue entry now that Xcode 5 has been released.
