on Leopard during compilation should make it run on a Tiger, too.
I tried that, too, but it somehow only works partially. If I build ghc with that environment setting, the GHC binary still has some Leopard symbols in it (though much less than without that setting). Specifically, I am seeing dyld: bind: ghc-6.9.20080219:_fcntl$UNIX2003$lazy_ptr = libSystem.B.dylib:_fcntl$UNIX2003, *0x0108a413 = 0x92c7b7bc on running env DYLD_PRINT_BINDINGS= compiler/stage2/ghc-6.9.20080219 Any idea why that may be? In contrast, if I instruct GHC's build system to use -optl-isysroot -optl/Developer/SDKs/MacOSX10.4u.sdk -optl-mmacosx- version-min=10.4 -optl-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk on all CC and LD targets, I don't seem to have any Leopard symbols anymore. FWIW, Xcode 3.0 also seem to use explicit SDK options. Manuel
