Qt Creator can't find library file

I have added a lib like this in my .pro file:

unix {
    LIBS += ../lib_dir/myLib.a

    //other includes not related to this
}

And when I try to build I get "undefined reference" errors for every function used from this lib and an error: 

File not found: ../lib_dir/myLib.a(myLib.o)

What could I be doing wrong?

EDIT:

Here is what I have written: 

LIBS += -L../lib_dir -lmyLib

Here is the file path: 

/home/livanov/Project/lib_dir/myLib.a

Here is the path of my project that uses the lib: 

/home/livanov/Project/client_app
Solution

  • Try using the form described in qmake's variable reference:

    unix {
    LIBS += -L../lib_dir -lmyLib
}

    If the path to your library contains spaces, use quotes:

    unix {
    LIBS += "-L../lib dir" -lmyLib
}

    If that doesn't work, we'll need to see the actual path to your library.
