Source Insight Parse Build Output

Source Insight Parse Build Output

I'm working with source insight IDE, I want to run the compilation with
its custom commands option. I want it to parse my results and create links
for me for the places where I have warnings. I made the command, and
captured the output but can't create the regex right The formatting is:
\.c: I tried to do a regex with 2 groups but it raises an error about
needing one group for errors or something.
Thanks in advance
