XCode 3 static library dependency linking

Hi,

I wonder if someone might shed some light on the way dependencies work
in XCode 3. I've found that I can drop either a statically compiled
library file itself into the External Frameworks group of an
application project and it links correctly. However this does not
allow it to be specified as a direct dependecy when editing the Target
application. Dropping the xcodeproj itself into the External does
allow for this direct dependency and once added goes as far as even
specifying the library path amongst the search paths for the linker.
However, the actual library file is not actually linked to the
application despite being properly compiled upon compiling the main
application.

I seem to be able to work around this problem by dropping both the
compiled lib file and the xcodeproj into the External Frameworks but
this seems like such a bizarre solution to me especially since opening
the added xcode project reveals the same .a file reference inside it.

Anyone know how this should be done properly?

Thanks

It's very simple.

If you add project A to project B then targets in B can depend on targets in A.

If you make target A1 a dependency of target B1 (which you can do in target
inspector for B1), then building B1 will also build A1.

If you want B1 to link against the product of A1, then you need to add the
product of A1 to B1, just like you would with any other library you want B1 to
link against. You can do this simply by dragging the product of A1 to the Link
Frameworks and Libraries phase of B1. You can find the product of A1 listed
under A's entry in the project tree.

In short, dependencies are orthogonal to linking, and if you want both, you need
to specify both.
