No, Xcode can use static archives just fine.
1) For your tool target "reader", add a "Frameworks and Libraries"
phase if it doesn't have one already. Project > New Build Phase > New
Frameworks and Libraries Phase
2) Add the library. Projects > Add Frameworks... Navigate to your
static archive. Add it to the appropriate targets via checkboxes
3) If you later need to add it to other targets, drag the reference
in your project hierarchy to the appropriate "Frameworks and
Libraries" phase

I don't think you are contradicting what I said, just helpfully expanding it. Was I wrong to say that you cannot use use '-lfoo' on an ld command line if libfoo.a is a conventional archive? I certainly tried test cases on this and ld spat the dummy every time.

Not to derail the Xcode discussion, but you are certainly wrong that '-lfoo' fails to work with libfoo.a, using gcc/ld. I use this without problem (but I have yet to convince Xcode to work with my project, a separate issue).


What do you mean by gcc/ld?  How was libfoo.a created?

If I try something like
ld -o someexecutable grog.o bar.o -lfoo
where libfoo.a is an archive made with
ar -cru -o libfoo.a yuch.o grok.o blob.o
ranlib -s libfoo.a
I will get
libfoo.a is not a valid object file
and it wil break.

Are you saying this is different for you?

As I understand the docs
ld -static -o libfoo.a yuch.o grok.o blob.o
ranlib -s libfoo.a
ld -o someexecutable grog.o bar.o -lfoo
should work but I have never tried it because that is not where an autotools build ever gets you.
