    Default Qt Creator + gdcm (Grassroots DICOM): can't link libraries?

    I'm using Qt Creator 2.4.1 under Xubuntu 11.10.

    I've installed libgdcm2-dev (2.0.17) in repositories.

    Now I have

    /usr/include/gdcm-2.0
    /usr/lib/gdcm-2.0
    and a lot of *.so related to gdcm in
    /usr/lib/
    Writing code, I can autocomplete sentences with gdcm classes and functions (the IDE finds them), but compiling, it gives me error messages like:

    My code:

    Qt Code:
    1. #include <gdcmImageReader.h>
    2. ...
    3. gdcm::ImageReader ir;
    To copy to clipboard, switch view to plain text mode 
    I get:

    error: undefined reference to `gdcm::ImageReader::ImageReader()'
    I've tried with:

    Qt Code:
    1. #include "/usr/include/gdcm-2.0/ImageImageReader.h"
    To copy to clipboard, switch view to plain text mode 

    With this one, it works from a simple editor like Geany.

    In my .pro file I have

    Qt Code:
    1. INCLUDEPATH += /usr/include/gdcm-2.0
    2. LIBS += -L/usr/lib/
    To copy to clipboard, switch view to plain text mode 

    What could I try? Thanks.

    LIBS += -lgdcm

    :-1: error: cannot find -lgdcm
    That's what I get with the line

    LIBS += -lgdcm

    I had it commented. So I guess I've already tried before. I really don't know what to do.

    It works with a simple editor, so I suppose it is a problem with Qt Creator, in the .pro file.

    What does the following return?

    ls /usr/lib/lib*gdcm*.so

    /usr/lib/libgdcmcharls.so /usr/lib/libgdcmjpeg12.so
    /usr/lib/libgdcmCommon.so /usr/lib/libgdcmjpeg16.so
    /usr/lib/libgdcmDICT.so /usr/lib/libgdcmjpeg8.so
    /usr/lib/libgdcmDSED.so /usr/lib/libgdcmMSFF.so
    /usr/lib/libgdcmIOD.so /usr/lib/libgdcmopenjpeg.so

    You gave me the idea of adding

    LIBS += -lgdcmcharls -lgdcmjpeg12 -lgdcmCommon -lgdcmjpeg16 -lgdcmDICT -lgdcmjpeg8 -lgdcmDSED -lgdcmMSFF -lgdcmIOD -lgdcmopenjpeg
    and it worked!

    Thank you very much.

    Does the following return anything?

    pkg-config --list-all|grep gdcm

    If so, better use pkgconfig support built into qmake to set the libraries.
