Linking to multiple dll and lib files in qt
Ahti last edited by Ahti
I would like to know what is the proper way to link to multiple dll and lib files and how would I test if they are properly linked or not.
This is how I did it:
myproject . pro:
LIBS += -L$$PWD/dependencies -lole32 -ldxva2 -lwbemuuid INCLUDEPATH += $$PWD/dependencies DEPENDPATH += $$PWD/dependencies
I have created a folder namely dependencies inside my project directory and placed all the dll and lib files in it.
Looks ok but you are telling it to look for include files in
INCLUDEPATH += $$PWD/dependencies
which seems not to be the case.
Also, for system DLLs, like ole32, one normally does not copy it around but simply refers to it
LIBS += -lole32
and the compiler/toolchain should know how to get system DLLS.
To check what if it works, look in the compiler output pane.
You can see what it links to.
However, it will also give you linker errors if not found. ( and you used any of its functions)
