I　used genreflex to generate the dictionary, and I should have built the dictionary for the slot class. The following is part of requirements file which will generate the dictionary:

apply_pattern    install_more_includes more="EventDisplayBase"
apply_pattern    linker_library library=EventDisplayBase
apply_pattern    ld_library_path

apply_pattern reflex_dictionary dictionary=EventDisplayBase \
                               selectionfile=${EventDisplayBase_root}/dict/dict.xml \
                               headerfiles=${EventDisplayBase_root}/dict/dict.h

macro EventDisplayBaseDict_use_linkopts $(use_linkopts)

You can untar the tarball to check the fmwk/EventDisplayBase/dict/dict.{h,xml} for the dictionary classes.

Thanks,
Xinchun

    Cheers, Axel.

        Hi,

        I don't have LCGCMT nor Xerces-C, but I'll try to take a look as soon as
        possible, and I'll let you know.
        In the meanwhile, you can check that the slots really exist by looking
        in the code (they should be public methods)

        Cheers, Bertrand.

        Dear ROOTers,

        I am in the process of converting SRT managed FMWK project
        (http://enrico1.physics.indiana.edu/fmwk/wiki/index.php?n=FMWK.FMWK?from
        =Main.HomePage) to a CMT project. I used LCGCMT as the glue package and
        the policy is basically from GaudiPolicy with slightly modification. The
        conversion is almost done, but get problems on EventDisplayBase package
        which is using signal/slot communication mechanism.

        If you happen to using LCGCMT, and have ROOT/Xerces-C installed, it is
        quite straightforward to build EventDisplayBase and reproduce the error.
        The tarball is attached.

        The SRT version of EventDisplayBase works well.  The ROOT version is
        5.22.00c, the systems are Mac OS 10.5.8 and Sci. Linux Fermi 4.4.

        Any help? Thanks in advance.
