I have checked that the examples given still build with a newer version
of ORBit (i tried 0.5.12 ). It works. Which ORBit are you runnning ?

The impl_Calculator__create() function is part of the stubs generated
by orbit-idl and this one should go in calculator-impl.c in this
example.
Normally, the stubs are generated the first time with 
orbit-idl --skel-impl calculator.idl, which produces
calculator-skelimpl.c.

In this example calculator-impl.c is included in calculator-server.c.

So your output seems to indicate that the link does not include
calculator-server.o where the function definition lies.

The output of the make should look like :

[genaud@guenievre calculator]$ make
/usr/bin/orbit-idl calculator.idl
gcc -I/usr/include/glib-1.2 -I/usr/lib/glib/include
-I/usr/include/orbit-1.0   -c -o calculator-client.o calculator-client.c

Hope it helps.
