Needing urgent assistance on my project

[Ivica Bukvic]

Hi all,

I've been expanding my app by adding a third-party C-based functionality
(my app is C++/Qt). The problem is that I designed a new class (derived
from the QWidget) which includes the .h files from the 3 C-based files.

What happens is that the class is currently fully implemented but there
is no instance created within the main app (I don't know if this may be
a problem). So, when I compile the app, everything compiles just fine
until the final linking of all .o and moc.o files when I get bunch of
errors as follows:
g++ -O2 -O0 -Wall -fno-exceptions -fno-check-new -o rtmix OSC-timetag.o

I am pretty sure that something trivial is screwed up, but I have no
idea what. Could someone please help me figure this thing out. Thank you
very much! Sincerely,

P.S. I am cross-posting this on the Kdevelop list since I am using
Kdevelop for my development.
