I've downloaded QtSingleApplication from the QtSolutions.
The install text says I should :
unzip,
run qmake
run nmake
add "include(your-install-dir/src/some-package.pri)" to the .pro file
run qmake on the .pro file.

I'm using MSVC, I'm not using pro files (am I?) I have the .h file included in my project. I can even bind the .h and .cpp into the project. but I still get unresolved external symbol linker messages.
can anybody tell me what's going on? and how I can get the classes into my msvc project
