First, I'm not asking how to include includes in a syntastic check. I already have:

let g:syntastic_c_check_header = 1

And when I run :SyntasticCheck, or save, a .cpp file, it also checks relevant includes if they are in syntastic_c_include_dirs. It even opens an error location_list window in the buffer containing the .hpp if I then jump to it.

That's great, but what it won't do is check the header directly, whether I save it or use :SyntasticCheck in the .hpp buffer.

This means when working on template classes made only of an .hpp, I have to load some file that uses it and run the check from there; sometimes the easiest way to do this is to just create a dummy .cpp file with one line in it (#include "foo.hpp"). But this is still stupid and annoying.

Is anyone aware of a way to get Syntastic to check a C++ header directly, without having to run a check on file which uses the header?

  • Have you tried setting g:syntastic_cpp_check_header to 1 instead of g:syntastic_c_check_header? – lcd047 Sep 26 '16 at 14:27
  • @lcd047 :/ I know that maybe qualifies this for "whoops, delete, ignore me..." but if you want to put it in an answer, please do. – goldilocks Sep 26 '16 at 14:33

Or maybe that's just me. I had not noticed there's separate but similar options for C and C++.

let g:syntastic_cpp_check_header

Does the trick.
