I just upgraded to Xcode 2.3 from Xcode 2.2.1. I have a set of plug- in projects that I'd imported from CodeWarrior to Xcode 2.2. Before upgrading, the plug-ins built and ran correctly on both PPC and Intel machines. After upgrading to Xcode 2.3, the plug-ins no longer load on Intel, even though the plug-ins show up as Universal in the Finder's Get Info window.

I looked at the build folder for one of the plug-ins. The (apparently unstripped) PPC binary is 500K and the Intel binary is 52K; the stripped Universal binary is 92K.

If I run "nm -a -arch ppc ..." and "nm -a -arch i386 ...", the PPC version displays the global and unresolved symbols and the i386 version only displays "nm: no name list".

If I run "lipo -detailed_info ..." on the Universal binary, it reports the following:
fat_magic 0xcafebabe
nfat_arch 2
architecture i386
    cputype CPU_TYPE_I386
    cpusubtype CPU_SUBTYPE_I386_ALL
    offset 4096
    size 4096
    align 2^12 (4096)
architecture ppc
    cputype CPU_TYPE_POWERPC
    cpusubtype CPU_SUBTYPE_POWERPC_ALL
    offset 8192
    size 83984
    align 2^13 (8192)
Any idea what's changed in 2.3 that could be affecting this?

I realized that I should probably give more details about my setup but forgot last night. Chalk it up to a long day.

- Building against 10.4u SDK - PPC: gcc 3.3, 10.3 deployment target - Intel: gcc 4.0.1 (default), 10.4 deployment target - generate debug symbols, level = full - symbols hidden, inlines hidden, virtuals hidden, locals hidden - dead-code stripping, deployment postprocessing, strip linked product, separate strip, strip non-globals

Here's the build transcript (long file paths cleaned up for readability):
