Well, the installed version of the dot tool has 4 architectures:

ppc i386 64-bit ppc64 64-bit x86_64

The installed expat library comes back as i386. So dyld should be fine, right?

If a command line app has both 32 and 64 bit versions available and is executed on a 64 bit machine, then the 64 bit version will be executed. Use

arch -i386 dot ...

to force the OS to start the 32 bit version. I also wonder why your expat library is missing three quarters of the archs that Apple ships.

The expat thing is almost certainly not Apple's fault; I got desperate when dot didn't work so I recompiled and installed expat myself. If the build system doesn't properly build all the architectures, then (of course) my newly installed libraries won't have all architectures. I have not checked to see if libexpat does have proper makefiles, but I can do that later on (more pressing issues now) If someone has an OS X 10.5.6 distribution that doesn't have their own libexpat installed over Apple's and is able to double check this, can you please post to the list if Apple IS shipping a library that only has one architecture?

The installed version of libexpat.1.5.0.dylib on my Intel 10.5.6 machine has all 4 architectures (32/64 bit PPC & 32/64 bit 386)

OK, so somewhere in the mess of installing various bits, I messed up my libexpat. Rebuilding from scratch isn't working, so how do I reinstall it? Can I pull it off the Leopard DVD, or is it a Darwin project somewhere that I can download? Thanks, Cem Karan _______________________________________________ Do not post admin requests to the list.
