Here is a snippet of how to do it from within a .vimrc file to set your vim path option to gcc's standard system includes when vim launches.
You will need a vim compiled with the +perl option. The vim-full package on most linux distributions will have +perl enabled.
# ~/.vimrc perl << EOF my $std_inc_path = `echo | g++ -E -v -x c++ - 2>&1`; my $start_delim = '#include <...> search starts here:'; my $end_delim = 'End of search list.'; $std_inc_path =~ s/.*?\Q$start_delim\E(.*?)\Q$end_delim\E.*/$1/s; $std_inc_path =~ s/\s+/,/sg; $std_inc_path =~ s/(^\,)|(\,*$)//g; VIM::SetOption("path=.," . $std_inc_path . ",,"); EOF
