external links

I am trying to upgrade an existing and working c program that communicates to a device via usbhid program.
I have all the QT GUI stuff working fine, but now I need to add the additional links to all the usb programs.
It is open source, so I can see all the code.
I tracked back all the links and libraries needed and get NO errors.
I also get no verified communications.
I recreated the header files directly in the QT headers and copy/pasted the code just to make it part of the code instead of a link.

Any suggestions on the proper linking and debugging to verify?

I know this is vague, but I am looking more about QT style and prefered programming for C++.

Hi
Not sure what you are after so forgive if total miss :
You can add external files via the .pro file.
note the ALLPO paths. ( its sample so bit ugly)
those points to a folder above the project folder with some common files.
It could be anywhere on your PC. But it will get messy soon :)
And then i would set some breakpoints into the "old" code at
critical functions and see if all get up and running.

SOURCES += main.cpp\
    mainwindow.cpp \
    pxstyler.cpp \  
    ../AllPO/Source/Common/Platform/Trace/Terminal.cpp \
 ...
HEADERS  += mainwindow.h \
    configuration_dialog.h \
    ../AllPO/Source/Common/Platform/Trace/Trace.h \
....
INCLUDEPATH += $$PWD/../AllPO/Source/Common/Platform/Trace \
    $$PWD/../AllPO/Source/Common/Platform/Trace \
....

If I understand you correctly you already can build your app with UI and that C code, right? So, you have an executable? But the communication does not work? In this case you need to debug your app to see what happens. Does your UI already call this C stuff?

NO, I already have a terminal based c program that works fine.
Now I want to transfer the functionality to QT for the GUI interface.

I have a #include " program.h" in the main program that does not trigger a break in the program.h in the headers.

It's not enough to include the header - you should use that code. For me its not clear what you did and what does not work.
