" In order to also check header files add this to your .vimrc:
|
|
"
|
|
" 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 disable the include of the default include dirs (such as /usr/include)
|
|
" add this line to your .vimrc:
|
|
"
|
|
" let g:syntastic_c_no_default_include_dirs = 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_includes = 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:
|
|
"
|
|
" let b:syntastic_c_cflags = ' -I/usr/include/libsoup-2.4'
|
|
"
|
|
" In order to add some custom include directories that should be added to the
|
|
" gcc command line you can add those to the global variable
|
|
" g:syntastic_c_include_dirs. This list can be used like this:
|
|
"
|
|
" let g:syntastic_c_include_dirs = [ 'includes', 'headers' ]
|
|
"
|
|
" Moreover it is possible to add additional compiler options to the syntax
|
|
" checking execution via the variable 'g:syntastic_c_compiler_options':
|
|
"
|
|
" let g:syntastic_c_compiler_options = ' -ansi'
|
|
"
|
|
" Additionally the setting 'g:syntastic_c_config_file' allows you to define a
|
|
" file that contains additional compiler arguments like include directories or
|
|
" CFLAGS. The file is expected to contain one option per line. If none is
|
|
" given the filename defaults to '.syntastic_c_config':
|
|
"
|
|
" let g:syntastic_c_config_file = '.config'
|
|
"
|
|
" Using the global variable 'g:syntastic_c_remove_include_errors' you can
|
|
" specify whether errors of files included via the g:syntastic_c_include_dirs'
|
|
" setting are removed from the result set:
|
|
"
|
|
" let g:syntastic_c_remove_include_errors = 1
|
|
"
|
|
" Use the variable 'g:syntastic_c_errorformat' to override the default error
|
|
" format:
|
|
"
|
|
" let g:syntastic_c_errorformat = '%f:%l:%c: %trror: %m'
|
|
"
|
|
" Set your compiler executable with e.g. (defaults to gcc)
|
|
"
|
|
" let g:syntastic_c_compiler = 'clang'
