I have a problem with qmake and the make file that it generates. My program needs to be linked against two libraries. I add them in main.pro as follows.

LIBS += -L lib/somelib1/bin -lsomelib1 -L lib/somelib2/bin -lsomelib2

How ever I arrange the above line qmake tells gcc this.

g++ -o programname someobject.o -L lib/somelib1/bin lib/somelib2/bin -lsomelib1 -lsomelib2

The problem is that it should look like this.

g++ -o programname someobject.o -L lib/somelib1/bin -L lib/somelib2/bin -lsomelib1
-lsomelib2

GCC gives the following error.

lib/somelib2/bin: file not recognized: Is a directory

Thanks in advance.

    You should not put spaces between the flags and the arguments:

    LIBS += -Llib/somelib1/bin -lsomelib1 -Llib/somelib2/bin -lsomelib2

    Or 

    LIBS += -L"lib/somelib1/bin" -lsomelib1 -L"lib/somelib2/bin" -lsomelib2

    And why are your static/import libraries in the “bin” directory? There should be .a files in the “lib” directory.
