13 " in order to also check header files add this to your .vimrc:
14 " (this usually creates a .gch file in your source directory)
15 "
16 " let g:syntastic_cpp_check_header = 1
17 "
18 " To disable the search of included header files after special
19 " libraries like gtk and glib add this line to your .vimrc:
20 "
21 " let g:syntastic_cpp_no_include_search = 1
22 "
23 " To enable header files being re-checked on every file write add the
24 " following line to your .vimrc. Otherwise the header files are checked only
25 " one time on initially loading the file.
26 " In order to force syntastic to refresh the header includes simply
27 " unlet b:syntastic_cpp_includes. Then the header files are being re-checked
28 " on the next file write.
29 "
30 " let g:syntastic_cpp_auto_refresh_includes = 1
31 "
32 " Alternatively you can set the buffer local variable b:syntastic_cpp_cflags.
33 " If this variable is set for the current buffer no search for additional
34 " libraries is done. I.e. set the variable like this:
35 "
36 " let b:syntastic_cpp_cflags = ' -I/usr/include/libsoup-2.4'
37 "
38 " Moreover it is possible to add additional compiler options to the syntax
39 " checking execution via the variable 'g:syntastic_cpp_compiler_options':
40 "
41 " let g:syntastic_cpp_compiler_options = ' -std=c++0x'
