LXR Cross Referencer / Discussion / lxr-general: How to create a lxr project for C & C++ source indexing

Gaviraju - 2020-12-29

Hi,

I am new to the LXR project so can I know any video tutorials or documentation for the C & C++ source code project creation

Thanks

There are two main sources of information:

http://lxr.sourceforge.net (redirected to the https: site)

the User's Manual downloadable from the File tab, doc folder

The first one contains pages about installation and the third step is called Configuration. This is where you customise LXR after having installed it to apply it against your source code tree. This is very concise information.

Extensive information is given in the User's Manual.

Unfortunately, it is no longer possible to play a demo directly on SourceForge.

Hi,

According to the user-guide I followed the instructions but unfortunately I'm not able to view the source file in the browser.

Can you please check my configuration?
I'm using Ubuntu 18.04

Thanks
Gaviraju

I had a look at your lxr.conf.

You probably did not understand how to store your source tree and designate it. Here is how it should be organised:

/-- home -- / -- ubuntu -- / -- tree -- / -- v1 -- | | / -- v2 -- | / -- other -- / -- user --

Then parameter sourceroot contains /home/ubuntu/tree without any version subdirectory. The Version variable designates all versions, including the first one. Consequently, it should list v1 and v2, not only v2 as you did.

Consider reconfiguring your tree. This is very fast with the configurator (less than 1 minute with your simple case). Don't forget to rerun genxref once you've done it because the generated links depend on the tree description.

Hi,

I'm getting an error such as "the directory /$somepath does not exist or is hidden by exclusive rule"

But all the files present in the directory & it's not displaying in browser.
I'm using ubuntu 18.04, apache server.

Thanks

Hi,

Any update?

Unable to tell. Does the error really contains $somepath ? With an explicit $ sign? In which case, this means template expansion went wrong, but there is no "somepath" variable in any template.

Usually, this error is a consequence of a faulty lxr.conf configuration file or bad access rights on the source tree (a priori, I wave out this latter case).
