Hi,
We're using a PPC-only thirdparty framework, load it at runtime and
use CFBundleGetFunctionPointerForName to get function pointers. The
problem we're having is that the function pointers we get back seem to
be invalid (e.g. single stepping in gdb ends up in the middle of
_pbxgdb_objc_compute_super_class_list). Now, the weird thing is that
this only happens if our application is built against the 10.5 SDK.
Building against the 10.4u SDK works fine (but we need to use 10.5
APIs elsewhere in the app).
Does anyone have any ideas as to why compiling the app against the
10.5 SDK causes CFBundleGetFunctionPointerForName to fail for a
framework built against an earlier SDK (we don't have the source for
the framework and don't know how it was built)?
Jerry
