[ome-devel] Having trouble compiling cpp file with Makefile

[Bernhard Holländer]

Hi Josh and Nick,

maybe I'm missing something but omero::cast does not return anything,
though I would expect to segfault the TreeList example....

this is from https://trac.openmicroscopy.org.uk/omero/browser/trunk/components/tools/OmeroCpp/src/omero/templates.h

template<class T> std::vector<T> cast(omero::api::IObjectList& v) {
        std::vector<T> rv;
        omero::api::IObjectList::iterator beg = v.begin();
        while (beg != v.end()) {
            rv.push_back(T::dynamicCast(*beg));
            beg++;
        }
        // this is missing!!!
        return rv;
}

Nick, a good place to look for examples are the OmeroCpp tests:

Cheers! Bernhard
