I use OPAL library in my application (Visual C++ 2008 Express), I built static version of ptlib and opal, a sopied ptlibs.lib and opals.lib to my project's lib folder. I also copied ptlib's and opal's include directiores to my app's folder. I added lib files to a linker configuration and include dir's to project configuration.
It compiles but doesn'tlink. Why? Is it a bug in OPAL ?

why not create your project in the same solution as ptlib or opal? It makes sense that , configurations are not required then.
