generating suppressions for memory leaks

Question

I want suppress Valgrind's reporting of some "definitely lost" memory by the library I'm using. I have tried valgrind --gen-suppressions=yes ./a but it only prompts for errors such as "conditional jump or move depends on uninitialized value".

Is there a way to generate suppressions for straight-up memory leaks? If not, is it difficult to write them by hand? Valgrind's manpage seems to discourage it, at least for errors.

Answer 1

To be prompted for leaks that aren't generating errors, you have to run

valgrind --leak-check=full --gen-suppressions=yes ./a
