LXR Cross Referencer / Discussion / Open Discussion: Help needed for file search and .h files

madhi - 2007-07-20

I have configured lxr 0.3 and glimpse 4.18 to index my source code under Linux (SLES 9) with root privileges. File search & identifier works fine.
The first problem is that I am not able to work with free text search. Free text shows “ , line –“ as the result.

The next problem I am not open the .h files

Plz help me in addressing this issue.

The configuration of my lxr conf goes like this

Configuration file.

# Define typed variable "v", read valueset from file.
variable: v, Version, [/local/lxr/source/version], [/local/lxr/source/defversion]

# Define typed variable "a". First value is default.
#variable: a, Architecture, (i386, alpha, m68k, mips, ppc, sparc, sparc64)

# Define the base url for the LXR files.
baseurl: http://localhost/src/source

# These are the templates for the HTML heading, directory listing and
# footer, respectively.
htmlhead: /usr/www/lxrnew/http/template-head
htmltail: /usr/www/lxrnew/http/template-tail
htmldir: /usr/www/lxrnew/http/template-dir

# The source is here.
sourceroot: /usr/www/src/
#sourceroot: /usr/www/src1/
srcrootname: Path:

# "#include <foo.h>" is mapped to this directory (in the LXR source
# tree)
incprefix: /include

# The database files go here.
dbdir: /usr/www/dbdir/

# Glimpse can be found here.
glimpsebin: /usr/www/dbdir/glimpse

# The power of regexps. This is pretty Linux-specific, but quite
# useful. Tinker with it and see what it does. (How's that for
# documentation?)
map: /include/asm[^\/]*/ /include/asm-$a/
map: /arch/[^\/]+/ /arch/$a/

  Hi,
  
  > The first problem is that I am not able to work with free text search. Free text shows “ , line –“ as the result.
  
  This is easy to solve.
  1. CD to /usr/www/dbdir/2.6.22 (or other version).
  2. run the command, "glimpse -H . linux".
  3. the above command should return hundreds of lines if everything is fine. LXR's role is just making fancy output. So if you fix the command to run, LXR works fine. I recommend you to first check the command path and access permissions of .glimpse* files.
  
  > The next problem I am not open the .h files
  
  what's the output of ls -l /usr/www/src/?
  
  With your "lxr.conf", LXR expects to sess /usr/www/src/2.6.21, 2.6.22...
  Again, check the access permissions of files.
  
  Good luck. :)

  Hi Toshiharu Harada ,
  
  I am happy to receive a reply from you I could able to fix the ".h files" issue by your guidance.
  I am sorry to say that, in the previous posting instead of typing free text search I typed as file search.
  I could able to generate the glimpse and now also I am getting the same display
  as “, line –“ when I invoke free text search.I also checked the file permission for glimpse.
  But u have stated to use the option "glimpse -H . linux".
  What is the difference in using glimpse and glimpseindex to build the glimpseDB?
  when I invoke free text search(search file) i have noticed in the line no :61
  
  unless (open(GLIMPSE, "-|")) {
  
  /****Control not going here*********/
  
           open(STDERR, ">&STDOUT");
          $!='';
  
          exec($Conf->glimpsebin,"-H".$Conf->dbdir,'-y','-n',$searchtext);
  
          print("Glimpse subprocess died unexpextedly: $!\n");
          exit;
  
  Control is not going inside the unless loop.
  Also not able to get where the binary glimpsebin is located, which is stated in exec command.
  I have installed glimpse in /usr/local/glimpse.
  
  This is the ls –l of   usr/www/src
  total 12736

  plz help me in resolving free text search.

    Just my pleasure. :)

    Read the f?cking manual! :(
    
    http://bases.colnodo.org.co/prensa/glimpseindex.html
    
    It is glimpseindex that build the glimpseDB.
    Glimpse is a command to do the search, not building index.
    
    If you search "linux" with LXR, what LXR does is invoke the "glimpse -H . linux" and some decorations for ouput.
    
    File permissions look good to me.

    Madhi,
    
    glad to see you again, too.
    I'm monitoring this forum, so changes are sent via e-mail.
    (I live in Japan)
    
    I think you are very close to the goal.
    So don't give up and keep trying.
    
    May the Force be with you...

  According to your lxr.conf,
  "/usr/www/dbdir/glimpse"
  must resides and must be executable from within CGI.
  
  There's one very simple yet powerfull debug method.
  
  % cd /usr/www/dbdir
  % mv glimpse glimpse-bin
  % vi glimpse
  % chmod a+x glimpse
  
  You can put whatever you need to debug your LXR.
  You might want to include the code to redirect
  the result to a temp file.
  
  If you follow this way, you'll soon get to know what is happening.

  hi Buddy good news.......,
  
  The path "glimpsebin: /usr/local/glimpse/bin/glimpse" which u gave worked very well.At first sight i dint check it.Now it works for all versions which i have indexed.
  Thanks Harada, for the help provided and relived me from the weired situation.
  
  Take care.Be happy.......
  
  Cheers,
  Madhi.

  Good news, finally!
  
  I believed you could make it, and you did it.
  LXR is one of the greatest programs and I love it.
  
  Enjoy!
