Runtime dependencies come from the install_name of the linked library, not from the filename that was passed to the linker. > when building against the 10.4u SDK (if I were building against the 10.5 > SDK, I'm sure it would link against libcurl.4.dylib and not work with Tiger > anymore). That's why (well - one reason why) you need to use the SDK that corresponds to the oldest version of Mac OS X on which your app will run. If you use a newer SDK, the symlink will resolve differently and you'll end up linking to a library that isn't available on older OS versions. > To make my app launch on Panther, I've been using a custom SDK I made which > is identical to the 10.4u SDK except with libcurl.2.dylib from Panther in it > when compiling for PPC (compiling for Intel uses the regular 10.4u SDK, of > course).
