How to stop treating warnings as errors

Question

I've gotten to the point in my custom Wireshark build for Windows that all that's left now is warnings--but these warnings are being treated as errors. As the vast majority of them are harmless (unused variabled, for example) is there any way to set it so that warnings are not treated as errors?

Answer 1

For Windows nmake builds, edit the following part of config.nmake as described in the comment:

#Comment out the following if warnings are not to be treated as errors
WARNINGS_ARE_ERRORS=-WX

As Jaap says though, there should be no warnings, all of the core Wireshark code is expected to build without any warnings and your custom code should too.

You might also run the perl check* scripts in tools, as they also pick up errors.

Answer 2

Have a look at this configure option --enable-warnings-as-errors. Assigning it 'no' should prevent them from happening. But even better, clean up your code to get rid of them, if you can.
