Yes!

Somewhere in a C++ learning book should be told that mixing
binary code from different compilers, even from different
versions of the same compiler, for instance G++, isn't
possible :(  The "Name mangling in C++" in:

http://en.wikipedia.org/wiki/Name_mangling

tries to explain the issue. So you should try G++ with the
Xerces and Xalan libraries too or use aCC (A C++ compiler too?)
for everything.
