Working with a static library I have written in Qt

[Guilo]

Hi all !

Here is my problem : I have a project that has two subprojects, both are libraries. One is QJson and the other one is home-made and uses Qt. I then have an other project that will use these two libraries. I want this main project to use my set of library statically.

Here is what I have in my .pro :

LIBS += -L$$PWD/../../../libmylib/lib/
LIBS += -lqjson -lmylib
 
 
INCLUDEPATH += $$PWD/../../../libmylib/include
DEPENDPATH += $$PWD/../../..libmylib/include

LIBS += -L$$PWD/../../../libmylib/lib/
LIBS += -lqjson -lmylib


INCLUDEPATH += $$PWD/../../../libmylib/include
DEPENDPATH += $$PWD/../../..libmylib/include

To copy to clipboard, switch view to plain text mode 

Everything works fine under MAC OS X.

Now, I want this project to work on Windows. And here are the issues. My main project complains about undefined references to mylib. MyLib project has generated qjson.a and qjson.dll, mylib.a (no dll).

Shouldn't my library be outputed as a .lib ? Why don't I have a dll for mylib ?

Thanks

The linker command typically assumes dynamic linking, try listing the library file explicitly:

LIBS += -lqjson  $$PWD/../../../libmylib/lib/mylib.a

LIBS += -lqjson  $$PWD/../../../libmylib/lib/mylib.a

You are getting the .a suffix because you are using (I assume) the MinGW/GCC compiler.
You get no DLL because I assume you pro file for mylib specifies static in the CONFIG variable.
