For a similar issue (huge legacy code base with thousands of compiler
warnings) we have simply created a script which checks the output of the build
against a known reference build, and then complains if the new build contains
warnings not found in the reference build.
The script basically uses the following algorithm:
- For both logs, extract all warnings and remove all line number
references. This results in two temporary files.
- Sort each temporary file and diff the resulting two files.
- Output all warnings found in the second file but not in the first.
From time to time (mostly before a new release) we allocate a few days to
systematically fix all warnings in a given component, and create tickets for
warnings which turn out to be real issues.
After each release the reference build log is then updated.
Over the course of about five years, this has helped us to bring the warning
count down from about 4000 to about 300, and to get the most critical
components free of warnings.
