LXR loads the source files directly from there, they are not saved in
the database.

This is puzzling - as far as I can see the configuration is correct
and you should be seeing the source files.

Can you confirm that genxref has successfully put data in the database
- ie you saw a log of each file processed when you ran genxref, and
the database has contents?  If that's the case then LXR can definitely
find the code.

When you say the portal displays fine at http://myip/lxr/source/, do
you mean you see the LXR header etc but where you would expect to see
a listing of the top level directory of the source code you see "The
directory / does not exist"?

If none of those provide a eureka moment then could you try adding
some debug prints to LXR to see what's going wrong?

- At around line 150 of source, where it reads:
  151 @nodes = $files->getdir($dir, $releaseid);
  152 	unless (@nodes) {
  153 		print(  "<p align=\"center\">\n<i>The directory " . $dir
  154 			  . " does not exist.</i>\n");

Can you add a print of $releaseid and $files

Then in lib/LXR/Files/Plain.pm at line 99
  99    sub getdir {
  100 	my ($self, $pathname, $releaseid) = @_;
  101 	my ($dir, $node, @dirs, @files);

Add a print of $pathname, $releaseid, and at line 108
107 	$dir = $self->toreal($pathname, $releaseid);
  108 	opendir(DIR, $dir) || return ();

add a print of $dir which will show what directory LXR is trying to open.

Hopefully one of these will reveal what's going wrong!

Cheers,

Malcolm
