    Default QtCreator .pro file question

    I can't seem to get a library linked. The library is libusb-1.0.


    I have the following line in my .pro file:
    LIBS += -L/usr/local/lib -llibusb-1.0


    I get the following error during a build (clean/qmake/rebuild all):
    /usr/bin/ld: cannot find -llibusb-1.0


    I'm sure that the library is on my system. The results of #locate libusb-1.0:

    /usr/local/include/libusb-1.0
    /usr/local/include/libusb-1.0/libusb.h
    /usr/local/lib/libusb-1.0.a
    /usr/local/lib/libusb-1.0.la
    /usr/local/lib/libusb-1.0.so
    /usr/local/lib/libusb-1.0.so.0
    /usr/local/lib/libusb-1.0.so.0.0.0
    /usr/local/lib/pkgconfig/libusb-1.0.pc


    I tried changing the .pro line to all of these with no success:
    LIBS += -L/usr/local/lib -llibusb-1.0.so
    LIBS += -L/usr/local/lib -llibusb-1.0.so.0
    LIBS += -L/usr/local/lib -llibusb-1.0.so.0.0.0



    Any ideas what I'm not doing or doing incorrectly?

    Thanks!

    Qt Code:
    1. -llibusb-1.0
    To copy to clipboard, switch view to plain text mode 
    I think the "lib" is not needed here, try
    Qt Code:
    1. -lusb-1.0
    To copy to clipboard, switch view to plain text mode
