Building a set of static, profile GNUstep libs (almost there, so close)

[Michael Hanni]

Hi,

I finally got all the libraries to compile profile, static, debug and I even
got gpbs to link and give profiling information. However, this information may
be screwed up or just plain wrong -- I'm still trying to chase the loose ends.

Anyways, a little of the profile for gpbs:

Flat profile:

Each sample counts as 0.01 seconds.

Anyhow, there are quite a few -gui classes in play when you fire up gpbs
according to this profile run -- I'm not sure if it all makes sense, but... :-)

So, gpbs can be run and gives some -- reliable or not -- profiling data. Alas,
anything that has to initialize the backend dies saying it can not find the
backend context. I've compiled -back as a library and it links with all its
libraries just fine. I can use "nm" and see that it has all the right symbols,
but after I compile it into an application all those symbols disappear (thus
the backend context can not be found.)

Is there some "nm" magic or "ld" voodoo I can do to see where my symbols are
going? If I could just get past this last obstacle I could profile the hell out
of things.

I'd appreciate any insights!
