I have to complete a software project which was left unfinished by someone else.
Initially the code I had did not require a dictionary to be generated as I was not using Signals and Slots.
I declared a TTimer object and tried to use Signals and Slots.
A smaller version of the software with the sample code as per the example provided in ROOT documentation works ok.
But When I try to scale up and implement the timer functionality in the larger software the error messages displayed below.
Without the timer code and without the Signals and Slots code the software was in working condition and I could generate the executable code and run it.
I have used ClassDef(classname,0); as the last line before closing braces in the header file of each class and
ClassImp(classname) as the first line in the corresponding class implementation file *.cpp.
and first generated the dictionary file using : make dict and then the command make to generate the executable code which is not being generated and the following error messages are displayed.
errors as follows:
