Hi John,

I see at least one reason why: you did not link in a library or an object
file containing code from CCC.cpp.

A quick and dirty solution (just to see if it works) is to replace the
following lines in your Makefile template (in the sip file)
> MMM_SOURCES = \
>  $S \
>  MMM.py
by 
MMM_SOURCE = \
    CCC.cpp \
    $S \
    MMM.py
and put CCC.cpp in the directory where sip puts its generated generated
source code.

Later, you could make a library out of CCC.cpp & friends, then you have
to add a library libCCC.so to

>lib$mcmodule_la_LIBADD = -L/usr/lib/qt2/lib -L$$(DESTDIR)$$(libdir) -lqtcmodule <- add
libCCC.so (order of linking might be important).

With such changes it might work. Since you are using libtool-1.4, I would
advise you to remove the libqtcmodule-2.5.la file from
/usr/lib/python2.1/site-packages/
(libtool-1.4 is much stricter than previous versions and imposes its own
linking order -- this interferes order of initialization of static objects in
C++ libraries -- you might get away with it this time, but expect erratic
behaviour).

Hope this helps, Gerard
