Have you tried asking Intel? The /usr/include/AvailabilityMacros.h will then take care of turning that into MAC_OS_X_VERSION_MIN_REQUIRED. For the linker, if using the underlying ld or if using Intel's compiler driver and it uses the underlying LD: If linking an executable tell the linker not to add the default CRT startup and instead add the pre-10.5 compatible crt1.o to the end of the files list. This will make it link with the old crt1.o instead of the new Leopard-only crt1.10.5.o. There are similar steps if you're doing a dylib or bundle (they have their own .o files equivalent to crt1.o).

In that case, try using that parameter to pass the following to ld: (note: those underscores are *not* a typo, ld expects underscores as opposed to gcc; also, ld does not want an equals sign).

Prior to Leopard's GCC, the compiler used 10.1 when compiling ppc code and 10.4 when compiling x86 code. I suspect the reason for this change is the UNIX compliance. Unless you target 10.5 as the minimum OS X version, your code will not be UNIX compliant. Since code compiled with default compiler parameters must be UNIX compliant in order for the system to be considered UNIX compliant the compiler must use 10.5 as the default minimum OS X version. If you don't care about UNIX compliance and want the library to work on prior OS X versions the fix is to add -mmacosx-version-min=10.4 to your compiler flags. To be more precise, I found that some symbols were missing, and especially _close$UNIX2003 _fputs$UNIX2003 _fwrite$UNIX2003 _mktime$UNIX2003 _open$UNIX2003 _read$UNIX2003 _strtod$UNIX2003 _write$UNIX2003 This email sent to dfe(a)tgwbd.org This email sent to site_archiver(a)lists.apple.com
