I have a RedHat 7.3 and I have upgraded the gcc compiler from the old
unsopperted revision 2.96 to a newer rev. 3.4.6.
I got several incompatibility which I'm still fixing.
One of these is related to the xercesc code ( I'm using the xerecsc 2.7 ),
it's seems as if the namespace xerces is never recognized (ex. undefined
reference to `xercesc_2_7::XMLString::transcode(unsigned short const*)).

What I'm missing ?
Thank for the help I'll strongly hope you will give me.

I reported belowe a simple classe wich using xerces funzions

        char *str1 = XMLString::transcode( xml);
        int i = strcmp(str, str1);
        XMLString::release(&str1);
        return i;
}
