" 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_c_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_c_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_c_includes. Then the header files are being re-checked on
|
|
" the next file write.
|
|
"
|
|
" let g:syntastic_c_auto_refresh_headers = 1
|
|
"
|
|
" Alternatively you can set the buffer local variable b:syntastic_c_cflags.
|
|
" If this variable is set for the current buffer no search for additional
|
|
" libraries is done. I.e. set the variable like this:
