" in order to also check header files add this to your .vimrc:
" (this usually creates a .gch file in your source directory)
"
"   let g:syntastic_cpp_check_header = 1
"
" To disable the search of included header files after special
" libraries like gtk and glib add this line to your .vimrc:
"
"   let g:syntastic_cpp_no_include_search = 1
"
" To enable header files being re-checked on every file write add the
" following line to your .vimrc. Otherwise the header files are checked only
" one time on initially loading the file.
" In order to force syntastic to refresh the header includes simply
" unlet b:syntastic_cpp_includes. Then the header files are being re-checked
" on the next file write.
"
"   let g:syntastic_cpp_auto_refresh_includes = 1
"
" Alternatively you can set the buffer local variable b:syntastic_cpp_cflags.
" If this variable is set for the current buffer no search for additional
" libraries is done. I.e. set the variable like this:
"
"   let b:syntastic_cpp_cflags = ' -I/usr/include/libsoup-2.4'
"
" Moreover it is possible to add additional compiler options to the syntax
" checking execution via the variable 'g:syntastic_cpp_compiler_options':
"
"   let g:syntastic_cpp_compiler_options = ' -std=c++0x'
