Hi,
I've had a user complain that my program crashes on his G3 running 10.4.11. The crash log says: "Link (dyld) error: incompatible cpu-subtype" and not much else. The program runs fine on my G4 10.5. It also works for other users using G4 10.4.9 and above. So I think the problem is the processor rather than the operating system.
Someone reported a similar problem in this thread:
http://www.cocoabuilder.com/archive/mess.../4/17/5681
But it didn't seem like they managed to resolve it.
Running otool -h on my program yields the following:
* cputype: 18
* cpusubtype: 0
In "machine.h", I found:
#define CPU_SUBTYPE_POWERPC_ALL ((cpu_subtype_t) 0)
So I think the cpu subtype is correct.
Running otool -L on my program shows that the program links to:

All of these are Apple libraries, except for Sparkle. When I run otool -L on Sparkle, it says:
* cputype: 18
* cpusubtype: 0
Here are the arguments I'm passing to gcc:
/Developer/usr/bin/gcc-4.0 -x objective-c -arch ppc -pipe -Wno-trigraphs -fpascal-strings -fasm-blocks -Os -mdynamic-no-pic -Wreturn-type -Wunused-variable -fmessage-length=0 -mtune=G5 -fvisibility=hidden -mmacosx-version-min=10.4 -I/Users/wedaly/Desktop/trunk/build/hip_cat.build/Release/Accompanist.build/Accompanist.hmap -F/Users/wedaly/Desktop/trunk/build/Release -F/Users/wedaly/Desktop/trunk/Libraries -I/Users/wedaly/Desktop/trunk/build/Release/include -I/Users/wedaly/Desktop/trunk/Libraries/FTGL/include -I/usr/local/include/freetype2 -I/Users/wedaly/Desktop/trunk/build/hip_cat.build/Release/Accompanist.build/DerivedSources -isysroot /Developer/SDKs/MacOSX10.4u.sdk -include /Library/Caches/com.apple.Xcode.501/SharedPrecompiledHeaders/hip_cat_Prefix-aykibdocjsqrovgqtpxanaibqvdp/hip_cat_Prefix.pch -c /Users/wedaly/Desktop/trunk/Sources/SongView.m -o /Users/wedaly/Desktop/trunk/build/hip_cat.build/Release/Accompanist.build/Objects-normal/ppc/SongView.o
FTGL and freetype both have the same cputype and cpusubtype as Sparkle and the application itself.
The notes for -mtune say that it should work for older processors.
Any ideas?
Best,
Will
