If you are willing to database for a downloaded source, change following stuff in lxrng.conf

use LXRng::Repo::Plain;

my $plainrepo = LXRng::Repo::Plain ->new('Source Path');

ver_list => ['Project Name'],
ver_default => 'Project Name',

Possible lxrng.conf example with two applications.

I’m still suffering to make it to show hyperlink lists shows up. I guess it’s because it failed to execute ‘ctags-exuberant’ because I saw lots of messages regarding that as is shown below.

Can’t execute “ctags-exuberant”: No such file or directory at ./lxr-genxref line 191.”
