You are right. This will not work on 10.3 simply because 10.3
installations are not capable of building universal binaries. I have
just added a warning (we could transform it into an error) when the
+universal variant is selected on machines where the Universal SDK is
not installed. This will cover machines running 10.3 and incomplete
10.4 installs.
What is the difference between a warning and an error? Are you saying it
just prints a message, then tries to continue? How could it succeed if
the universal SDK is not present?
I realize that this code should be modified when Leopard will be out,
for example, we should not specify 10.4 universal SDK on Leopard if
all the libraries there are universal. But I can only speculate for now.
I do not believe that any such changes would need to be made when
Leopard is out. Leopard should be able to run 10.4 universal binaries.
And we should continue to make 10.4 universal binaries even when on
Leopard, so that any universal binaries that were made there will still
run on 10.4. Are we setting MACOSX_DEPLOYMENT_TARGET=10.4? If not, we
should be.
I am not aware of your exact needs, but please note that MacPorts does
not produce 10.3.9 PPC + 10.4 Intel universal binaries.
And I don't think we should try to support 10.3.9 PPC + 10.4 Intel
universal binaries; it's too much of a pain. Unless we were to include a
trick like the unify script from the mozilla project in the macports
infrastructure somewhere. But even then, many software packages throw
considerably more fits when being cross-compiled than when they are
being universally compiled. (glib2: I'm lookin' at you...)
Agreed. This is not something I'm looking for support from the MacPorts
community.
But now that you mention this unify script from Mozilla, I'll check that
out for myself :)
