I'm having this problem, but I think I've got the SDK set correctly....

To recap:

I've got a project that builds universal. I'm doing a build where on PPC it is 10.3.9 and on i386, it is 10.4u:

Settings in Project:
	MACOSX_DEPLOYMENT_TARGET_i386 = 10.4
	MACOSX_DEPLOYMENT_TARGET_ppc = 10.3
	SDKROOT_i386 = /Developer/SDKs/MacOSX10.4u.sdk
	SDKROOT_ppc = /Developer/SDKs/MacOSX10.3.9.sdk

When I build, the precompiled header for my target compiles four times (2 architectures, by once each for C and C++):

From detailed build results:

	/usr/bin/gcc-4.0 -x c-header -arch i386 ...
	/usr/bin/gcc-4.0 -x c++-header -arch i386 ...
	/usr/bin/gcc-4.0 -x c-header -arch ppc ...
	/usr/bin/gcc-4.0 -x c++-header -arch ppc ...

However, when I do this, (even after manually clearing the cache), I get this error on linking:

/usr/bin/ld: warning /Library/Caches/com.apple.Xcode.501/ SharedPrecompiledHeaders/macutil_Prefix-gfvtyfrqzhtbgtdkbfnpcyzrwnfp/ macutil_Prefix.h.gch.o cputype (7, architecture i386) does not match cputype (18) for specified -arch flag: ppc (file not loaded)

Indeed, if I go to the cache and check the filetypes:

& cd /Library/Caches/com.apple.Xcode.501/SharedPrecompiledHeaders & file macutil_Prefix-*/*.o macutil_Prefix-abjtwqzwyamujjckvhsykvkxqive/macutil_Prefix.h.gch.o: Mach-O object ppc macutil_Prefix-awhadozoixxlekfaawslggtexfzo/macutil_Prefix.h.gch.o: Mach-O object i386 macutil_Prefix-dsaqnnxqjgkqmkfttdjqoackxtbp/macutil_Prefix.h.gch.o: Mach-O object i386 macutil_Prefix-gfvtyfrqzhtbgtdkbfnpcyzrwnfp/macutil_Prefix.h.gch.o: Mach-O object i386

Notice that there are three i386 and one ppc! The last one was compiled wrong! Here is the build line that generated it (last line reformatted to make it legible):

ProcessPCH++ /Library/Caches/com.apple.Xcode.501/ SharedPrecompiledHeaders/macutil_Prefix-gfvtyfrqzhtbgtdkbfnpcyzrwnfp/ macutil_Prefix.h.gch macutil_Prefix.h normal ppc c++ com.apple.compilers.gcc.4_0 cd /Users/markl/Projects/LL/mactel/linden/indra/newview setenv DISTCC_COMPILER "gcc version 4.0.1 (Apple Computer, Inc. build 5250)" setenv DISTCC_HOSTS localhost/2 setenv DISTCC_SYSTEM "10.4.5 (i386)"

/usr/bin/gcc-4.0 -x c++-header -arch ppc -pipe -Wno-trigraphs -fpascal-strings -faltivec -fasm-blocks -gfull -O3 -fmessage-length=0 -mtune=G4 -ftree-vectorize -fvisibility=hidden -fvisibility-inlines- hidden -Wno-invalid-offsetof -mmacosx-version-min=10.3 -I/Users/markl/Projects/LL/mactel/linden/indra/newview/build/ macview.build/Deployment-universal/AutoUpdater.build/AutoUpdater.hmap -Wmost -Wno-sign-compare -Wno-switch -mdynamic-no-pic -fpch-preprocess -F/Users/markl/Projects/LL/mactel/linden/indra/newview/build/ Deployment-universal -I/Users/markl/Projects/LL/mactel/linden/indra/newview/build/ Deployment-universal/include -I../../libraries/ppc-darwin/include -I../../libraries/include -I../llcommon -I/Users/markl/Projects/LL/mactel/linden/indra/newview/build/ macview.build/Deployment-universal/AutoUpdater.build/DerivedSources -DLL_DARWIN=1 -DLL_RELEASE=1 -DLL_RELEASE_FOR_DOWNLOAD=1 -DNDEBUG -fconstant-cfstrings -ffor-scope -Wno-reorder -isysroot /Developer/SDKs/MacOSX10.3.9.sdk -c /Users/markl/Projects/LL/mactel/linden/indra/newview/ macutil_Prefix.h -o /Library/Caches/com.apple.Xcode.501/SharedPrecompiledHeaders/ macutil_Prefix-gfvtyfrqzhtbgtdkbfnpcyzrwnfp/macutil_Prefix.h.gch -fsave-repository=/Library/Caches/com.apple.Xcode.501/ SharedPrecompiledHeaders/macutil_Prefix-gfvtyfrqzhtbgtdkbfnpcyzrwnfp/ macutil_Prefix.h.gch.o

Everything about this command looks right to me: It should be a precompiled header for C++, ppc, compiled against the 10.3.9 SDK.

Any clues on this one?
