create_prl and link_prl

**discostu** · 13th June 2007, 21:08

My application uses some libraries (that I wrote) which it statically links. When I recompile those libraries, I want my application to relink to those libraries when I "make" it. Right now it still just says "Nothing to be done for `first'"

The only info I've found on this is to put CONFIG+=create_prl in the .pro for the libraries and put CONFIG+=link_prl in the application's .pro. I've done this, but didn't seem to work. The .prl files don't seem to have anything about their sources/headers inside them.

The libraries and the .prl files go in a subdirectory lib/ and the libraries sources are in subdirectories in include/

Is this the correct way? If so what else do I need.

So no one knows how to setup qmake so that when static libraries are recompiled, the application will re-link against them?

Thanks.

I am also having this problem.

Ditto - I am having this problem as well. I've tried adding LIBS+= -L<path_to_lib.a> -l<lib> and it works if the <lib> is already compiled. But, I want make to detect changes to <lib> and automatically recompile it.
