[glade--]Compiling GUI source code error

I'm new to the area of C++ programming and GUI programming with GTK+ and 
GTKmm.  I have been trying to compile the source code for one of my test 
projects and I had to work through a couple of errors.  I finally got 
stumped by this latest error.  When I run "make" I get dozens of these:

/usr/lib/libgtkmm.so: undefined reference to `SigC::SlotDependent 
virtual table'/usr/lib/libgtkmm.so: undefined reference to 
`SigC::SlotData virtual table'
/usr/lib/libgnomemm.so: undefined reference to 
`gtkmm_signal_set_marshal(unsigned int, void (*)(_GtkObject *, void 
(*)(...), void *, _GtkArg *))'
/usr/lib/libgtkmm.so: undefined reference to `SigC::SlotDependent::Dep 
virtual table'
/usr/lib/libgnomemm.so: undefined reference to `SigC::Object::~Object(void)'
/usr/lib/libgnomemm.so: undefined reference to 
`SigC::ObjectScoped::~ObjectScoped(void)'

I know it can't find the libraries but they are there in /usr/lib/ but I 
can't understand why it can't find them.  I tried editing ld.so.conf and 
setting the LD_LIBRARY_PATH variable, and nothing worked.  Any info on 
this would be a big help.

Another note is that I'm also new to Linux and I am running RedHat 8.0. 
 I went through a lot of trouble installing the packages of GTKmm , 
libgtk, sigc++, etc...  Is there any one or few places I could go to 
that would have RPM's or binaries to install and work with RH 8.  I 
haven't figured out the art of installing things and I have already had 
to reformat once when trying to install libraries and other such 
involving GTK.  Any information or sites with information on this would 
be a great help also.  The HOWTO sites I found so far haven't been 
helping.  Thanks.
