Hello..can somebody please tell me how to get vim and a pdf viewer
(xpdf or evince of zathura) to work with vim lilypond-invoke-editor
function..i read everything that is on the web

An impressive feat.

and couldn't figure it out..thank you.

What is unclear with
<URL:http://lilypond.org/doc/v2.15/Documentation/usage/point-and-click>?

I put the command 'urlCommand "lilypond-invoke-editor %s"' at the end
of /etc/xpdfrc (i use archlinux)..and then when i tryed to hit a note
in xpdf it tryes to open emacs..the secend thing that i tryed is to
start gvim with options 'gvim --remote +:line:normcolumn myfile.ly'
and i get an error like this in gvim 'E492: Not an editor command:
:line:normcolumn|cal foreground()|if&im|star|en|redr|f' and this
'E247: no registered server named "GVIM": Send failed. Trying to
execute locally' in terminal..

I tought it is simple as that..but from mail-archive i saw that it is
more complicated than i tought..but still did not understand how to
set it up..

Have you set up your EDITOR environment variable?  I quote:

The program ‘lilypond-invoke-editor’ is a small helper program. It will invoke 
an editor for the special textedit URIs, and run a web browser for others. It 
tests the environment variable EDITOR for the following patterns,

emacs

     this will invoke

         emacsclient --no-wait +line:column file

gvim

     this will invoke

         gvim --remote +:line:normcolumn file

nedit

     this will invoke

           nc -noask +line file'

The environment variable LYEDITOR is used to override this. It contains the 
command line to start the editor, where %(file)s, %(column)s, %(line)s is 
replaced with the file, column and line respectively. The setting

     emacsclient --no-wait +%(line)s:%(column)s %(file)s

for LYEDITOR is equivalent to the standard emacsclient invocation.




From gvim's man page, I understand how one can position the cursor at startup on a line (+line or +:line), but I do /not/ grasp how it is put on a column. Indeed, gvim gives me an error if I follow the lilypond-invoke-editor example: the +:line:column syntax is wrong. The gvim/GVIM stuff on 'no registered server' (I think caused be the --remote flag) can be ignored, gvim starts up stand-alone anyway after that.

Evince appears to have its own set of obstacles. Some Ubuntu pages seem to suggest the problem (Permission denied) is related to apparmor.d but I have no clue how to make that behave as desired.
