I am wirting an application that uses the libpq interface to access
the PostgreSQL database. My system is Mac OS X.
I have set up my project in Xcode and everything works fine. DB access
is flawless and very fast. But I often like to dig deeper into things
to get knowledge on how things work. What confuses me is, when I use
otool to inspect my executable, I get the information that my app is
linked against libpq.5.dylib (which is a symlink to libpq.5.1.dylib),
which is probably the dynamic library that does the work in
communicating with the database server.
But what I don't understand: In my Xcode project, I have put libpq.a
(and not libpq.5.dylib!) into the linked frameworks of my project and
the project is build against it.
How does the linker know to link against libpq.5.dylib when libpq.a is
the only lib in my project?
I hope my problem description is not too confusing....
Thank you for any answer and thank you to the PostgreSQL team for the
great database! ;-)
