cppcheck can't find include files

c++ cppcheck

Solution 1

cppcheck is really bad at finding standard include headers, on Mac and Linux. Fortunately, you can suppress this check, and only scan your custom header files:

cppcheck --enable=all --suppress=missingIncludeSystem .

Solution 2

It isn’t recommended to provide the paths to the standard C/C++ headers - Cppcheck has internal knowledge about ANSI C/C++ and it isn’t recommended that this known functionality is redefined. But feel free to try it.

-I [dir]

Give include path. Give several -I parameters to give several paths. First given path is checked first. If paths are relative to source files, this is not needed.

cppcheck can't find even standard headers such as iostream. Any ideas?

I am using Ubuntu 11.04 and cppcheck from the repository.

  @tyz: I think the idea is that cppcheck knows about ANSI/C++ w/o any headers. So I think it won't even understand gcc specific system headers etc..

The -I option can make cppcheck run very slowly if you bring in a lot of headers.

And don't get it mixed up with the '-i' (ignore) option.

This supress-flag gives me the following error: Unmatched suppression: missingIncludeSystem... Or does this simply mean that the check didn't suppress any arror? Can I suppress the non-suppressed suppress-error then? O:)

I think this is a better answer, at least for me, my headers are not in to project root directory. So if suppressing the warning no headers will be checked.

Yes, you can suppress the 'unmatched suppression' error, with --suppress=unmatchedSuppression. :)
