How do I automatically set my VIM path option to the standard system include directories of gcc?

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 . ",,");
