Ray Smith has asked for the wisdom of the Perl Monks concerning the following question:

I am having difficulties installing the Event::Lib module. I user "cpan -t Event::Lib" to test. Can anyone give me a suggestion as to how to proceed? Thanks The bdginning of my output looks as follows:

Re: Event::Lib fails install test (cpan -t)
by chargrill (Parson) on Aug 29, 2007 at 16:22 UTC

    I tried running the tests on this module, but before I could even get there - I untar'd the tarball, then:

    $ perl Makefile.PL 
Checking existance of libevent...check.c:3:19: error: event.h: No such

Couldn't find libevent which is required 
for this module.

To obtain it, go to

    Have you made sure you have libevent installed?

      Thanks for the reply. However, in looking at the CPAN install output I see the following which, to me, implies that libevent is present:

Re: Event::Lib fails install test (cpan -t)
by liverpole (Monsignor) on Aug 30, 2007 at 15:42 UTC
    This is just a follow-up to explain how I got the Event::Lib module installed for Ray Smith (who is a coworker of mine).

    I noticed on his machine that he had installed libevent-1.3d into /usr/local/lib instead of /usr/lib, so I looked at the README file in /root/.cpan/build/Event-Lib-1.03, and found what looked to be a way to point to the /usr/local/lib directory instead: 

    In case you have several libevents installed and you'd like to use
the one in /usr/local/(lib|include):
                                                                      
+          
   perl Makefile.PL INC=-I/usr/local/include LIBS="-L/usr/local/lib -l
+event"
   make
   make test
   make install

    [download]

    Unfortunately, using the extra switches to Perl didn't seem to have any effect, the errors were the same as before.

    So I simply remade libevent, forcing the installation into /usr/lib, and that solved the problem -- his machine now successfully has Event::Lib installed.

    s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/

      Thanks for the help. Anybody know this manual change was necessary?

    Can't load '/root/.cpan/build/Event-Lib-1.03/blib/arch/auto/Event/Lib/Lib.so' for module Event::Lib: libevent-1.3d.so.1: cannot open shared object file: No such file or directory

    '/root/.cpan/build/Event-Lib-1.03/blib/arch/auto/Event/Lib/Lib.so' can be found - but it can't be loaded because 'libevent-1.3d.so.1' can't be found. I'm not a *nix person, so I'm unsure of the fix. Is it simply a matter of running ldconfig (from the command line) as root ?

    Cheers,
    Rob

      Thanks Rob, '/root/.../Lib/Lib.so' is there. Not being to familiar my self, I just tried: 
      ldconfig  root/.cpan/build/Event-Lib-1.03/blib/arch/auto/Event/Lib/Lib
+.so

      When re-running cpan -t Event::Lib, I still get the following:

      That's exactly right. The question is why do we get that missing library? I did install eventlib.
      From the cpan install:

      I just don't quite know what I've done wrong here. I had some trouble installing eventlib, but after getting a new version that appeared to work. I thought I was home free. Thanks for the interest.
