[Lxr-general] Newbie question

[Peter H. <ph...@oi...>]

I've tried to set up lxr as per the directions. The problem is, whenever
I try to follow a link from, say, $WEBHOME/lxr/http/source/linux-2.4.14,
such as to linux-2.4.14/kernel, what i hit instead is
/source/linux-2.4.14/source/linux-2.4.14/kernel. My lxr.conf reads in
part:

baseurl: http://www.ointment.org/lxr/http/
sourceroot: /usr/local/apache/htdocs/lxr/source/
# srcrootname: Linux
dbdir: /usr/local/apache/htdocs/lxr/source/
glimpsebin: /usr/local/bin/glimpse


I've created a <Directory> in my httpd.conf like so:

<Directory "/usr/local/apache/htdocs/lxr">
   Options All
   AllowOverride All
</Directory>

What am I doing wrong?  Thanks very much.

[Lxr-general] Problem with CVS backend and --allverions

[Joseph W. <jwi...@ou...>]

I'm using the most recent version of everything from CVS, and when I try to
run './genxref --url=http://cvs.mydomain.com/lxr' (Implicit --allverions), I
get nothing.. no errors or anything.  However, if I do
'./genxref --url=http://cvs.mydomain.com/lxr --version=1.2', it will
generate all the indexes for v1.2 (And also 1.1, oddly).

After a bit of searching, I believe I've pinpointed the problem to be in the
fact that LXR::Common::pathname is empty.  And since in lxr.conf, the
example for getting all CVS versions is as follows:
         'range'   => sub { return
                    ($files->allreleases(LXR::Common::pathname),
                     $files->allrevisions(LXR::Common::pathname))
                    }, # deferred function call.

It doesn't find a single version. (Not even the default version)

Any suggestions on workarounds or fixes for this? I'm up against a brick
wall at the moment on this one.

There are two possibilities that I can think of - either the script
/var/www/html/lxr/bin/genxref does not have the correct permissions to
allow your userid to access it, or some file under /usr/src/linux does
not have read access to your user.  To check if the permissions are ok
on genxref, use ls -l and check that either (a) you own the script and
the user permissions are r-x, or that your group owns the script and the
group permissions are r-x, or that all users (others) have r-x
permissions.

You can see if some file under /usr/src/linux is causing the problem by
looking at the output of 'strace genxref /usr/src/linux'.  This shows
the system calls being made, and should show you what file access is
causing problems.

The final possible reason (though unlikely) is that your copy of genxref
comes from a windows machine, and thus the line endings are wrong.  If
'perl /var/www/html/lxr/bin/genxref /usr/src/linux' works but executing
it at as command doesn't then this is a likely cause.

Cheers,

Malcolm

[Lxr-general] Permissions

[Joel D. <jd...@re...>]

I set up lxr twice on my machine and everything was perfect the first tim=
e. The second time however, even though i installed perfectly, i get an e=
rror 'bash: Permission denied', everytime i try to run /var/www/html/lxr/=

Why is that ???

[Lxr-general] Problem with Lxr

[Tao L. <ta...@vt...>]

hi, all,

I set up code cross-reference web by using lxr 0.3 before.
Now I want to cross reference a smaller source code for
a software. But I have difficulty when I open the browser
to localhost/lxr/http/source. It is said "This directory does not exist".
If I run the source script file from console, I can get the output
html file which correct reference inside it. I can search via
identifier search/free text search. But when I click one link in
the search result, I will get file does not exist error. 

I checked the .htaccess and access.conf files. They are the
same as the required. The prosperity of those perl scripts
are r and x for all users. 

Can you give me some advice on it? Thanks!

 Tao

You must enable cgi scripts in apache, did you do that?

Here's what my apache config files look like:

[Lxr-general] Include files and multiple versions

[Paul M. <pau...@ci...>]

Hi,

I'm using LXR 0.3 to index a system with multiple versions. Everything's =
going great - it really makes browsing the source easy - apart from the =
fact that I can't seem to get the include files properly set up such =
that they are linked from within the files where they are referenced.

Each version lives in a path like /view/version-name/... (we're using =
ClearCase). However, LXR does not seem to allow me to place my version =
variable in the incprefix part of lxr.conf - at any rate I can't get it =
to work - so I can't gain access to the header files appropriate to each =
version.

I've tried playing with the mapping sections in order to get this to =
work, but I've had no luck so far. Could anyone give me any pointers as =
to how to get this to work? Any help much appreciated.

I've also just installed LXR 0.8, and I guess I'll have the same problem =
there as well. So tips related to 0.8 as welcome too.

Cheers

Paul

Both the 0.7 and the current CVS version work for C/C++ at least as well
as the 0.3 release.  However, Java browsing is currently broken for both
- the fix is not complicated, but I haven't got round to it yet.  In
general I've found that the 0.7 version is much better than 0.3 - the
move to a proper database makes it *much* faster, and the use of ectags
makes the referencing better.

So my advice would be to go ahead and use the 0.7 or cvs versions. 
There are some major changes coming to cvs soon before a 0.8 release,
but upgrading should be easy.
 
Cheers,

Malcolm

[Lxr-general] lxr usability

[Ghozlane T. <gt...@pr...>]

Hello all...

i've been using lxr 0.3 a while back, and for various reasons lost access to
it.

i'd like to tryon the CVS version, and i have a few questions :
is this version useable ?
I mean i'm ready to tweak lxr code if i have to (did that on 0.3), but the
primary goal is to *use* lxr ... what are the issues/problems left open in
the cvs or 0.7,
can i expect it to work with the same features set as 0.3 ?


thank you for your help (and the work on lxr)
