[SOLVED] Can't link static library to executable - missing declarations?

[Peppy]

Here I am, again. This is output from Output panel (Compiling EXE with Project.Global.lib (static library)).
@
Project.Global.lib(SingleCoreApplication.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: bool __thiscall QLocalServer::listen(class QString const &)" (_imp?listen@QLocalServer@@QAE_NABVQString@@@Z) referenced in function "protected: void __thiscall Project::Global::SingleCoreApplication::init(void)" (?init@SingleCoreApplication@Global@Project@@IAEXXZ)

Something is missing...it's not available to linker, but what? I think it's missing Qt Classes, but I am not sure...

Do you want to link statically against the Qt library? Did you build a static version of the Qt library? Do you actually use the static build (you linker is obviously looking for an imported symbol from a shared library)?

[Peppy]

No. I am building application, which takes global static library Project.Global.lib, which includes classes SingleCoreApplication (SingleApplication). No, I didn't build static Qt libraries (Do I need it build?)

[lgeyer]

No you don't. Did you build the static lib against the same version of Qt?

[Peppy]

Yes, I do it on one place.

[lgeyer]

Just to be sure: have you added the network module to your .pro file?

[Peppy]

To Library or Application? To library yes, to application not.

DONE. It works, but. It don't show any console window (application is running)...

Check if you are missing a CONFIG += console in your .pro and if the subsystem type is Console (/SUBSYSTEM:CONSOLE) if you are using MSVS.
