    [Solved] MinGW linking issue

    My problem is a simple one - for some reason g++ does not find my libraries:

    g++ -LC:\avatar\boost_1_42\lib\ -oboost-test main.o -lboost_filesystem-mgw34-mt-d
    c:/qt/sdk_2010.02.1/mingw/mingw32/bin/ld.exe: cannot find -lboost_filesystem-mgw34-mt-d

    However, in path
    there are following files (among other boost libs):

    As far as I can tell, those parameters given to g++ should be enough to find the last file in the list above. They aren't, however, and I am out of ideas here.

    My environment:
    Windows XP
    MinGW 4.4 that comes bundled with 2010.02.1 Qt SDK.
    Eclipse 3.5 with CDT

    Turns out the linker does not in fact treat .lib libraries in the same way as it does for .a and .so libraries.

    Specify the libraries for the linker to use | MinGW

    When using .lib libraries, the linking parameter must be
    -llib<name> instead of just -l<name>
