Looking for a way to exclude files used by geninfo/genhtml

Question

We are trying to use geninfo and genhtml (alternative to gcovr, see here) to produce an html page using coverage provided by gcov.

However, the end result includes not only our code, but also files from /usr/include.

Does anyone know of a way to exclude these?

I tried looking at the man page but could not find anything http://linux.die.net/man/1/geninfo

If you're just looking to ignore files from /usr/include, a better option is probably "--no-external", which is intended for exactly this purpose.

lcov --no-external -d $(BLD_DIR) --capture -o .coverage.run

And as an extra: if you are building out-of-source builds; you can set source directories with `--directory` flag as much as you need, so that correct sources are found - because others will be omitted. – Ahmet Ipkin Apr 08 '16 at 12:03

You can use the lcov -r option to remove those files you aren't interested in.

lcov -r <input tracefile> /usr/include/\* -o <output tracefile>
