Summary: check_radius.c: In function `main':

Initial Comment:
When trying to compile on slackware I got the following

check_radius.c: In function `main':
check_radius.c:126: error: too few arguments to
function `rc_avpair_add'
check_radius.c:127: error: too few arguments to

I uninstalled the package ppp-2.4.2-i486-2 and redo a
make and all was fine.

After I reinstalled ppp-2.4.2-i486-2.

ppp-2.4.2-i486-2 has a file radiusclient.h.

i made two patches for this one. one using ifdefs all the time rc_
functions are called and one using wrapper functions for the majority(the
incompatible) functions of radiusclient.

Please post your objections about which approach we should check in..

I ran into this same problem.

The current radiusclient library (radiusclient-ng) has an 
updated API which requires a "config-file-handle" first 
argument to most of the API entry points.

I've updated check_radius.c to adhere to the new radiusclient-
ng API conventions.  Assuming that you have this current 
library installed, then check_radius.c compiles and link 
cleanly now.

I don't see where I can attach the updated check_radius.c file 
as an upload with this comment...  Let me know how I can 
send it in without opening a new case.

Note also that the configure script needs to be updated to 
check for libradisclient-ng (instead of libradiusclient).

Just an update to my previous post. I emailed the
distribution maintainer for Slackware, Patrick Volkerding.
Here is his response:

---begin quote---
Generally I won't move header files since their location
should be up to
the upstream maintainer(s), not me.  In this case the version of
radiusclient is rather old though, and perhaps it's useless
to everyone
anyway and should simply be removed.  You might try writing
to them to see
if they have an opinion about it, though.  Also, even if I
were to keep
the functional parts of the included radiusclient I could
remove the
header, .a library, and .so symlink if everyone is using
radiusclient-ng
to compile against now anyway.

Anyway, thanks for the info.  I'll ponder a bit whether
radiusclient is
useless on Slackware.  (it is to me, but... :)

Can we get a small note added to the README until a more
permanent solution is found? I will submit this to the
Slackware people to see if the radiusclient.h is even needed
in the ppp package, they might be able to remove it or move it.

hi,

thanks for the extra info.  i'll try and look more into this
in the next couple of weeks, and see if i can do some voodoo
in autoconf to determine the correct prototypes and version
of radiusclient.

Hi Guys

The problem isn't specific to Slackware. It is anyone that
runs with newer versions of the radiusclient library.

The REQUIREMENTS file says they can be found at
http://www.cityline.net/~lf/radius/ versions
radiusclient-0.3.1-1

That website no longer exists, but I have tracked down the
developer to
http://developer.berlios.de/projects/radiusclient-ng/

I was getting the same compile time errors on Solaris 8 with
radiusclient-0.4.9 as Sébastien. I downloaded an earlier
client library - radiusclient-0.3.3, which compiled, but I
have no idea on configuring, so doesn't seem to work.

It seems to me the radius client library has moved on, but
the Nagios plugin hasn't.

Since my site has moved to openradius, I will just use a
very simple shell script as a plugin to attempt login using
the openradius "radclient" program.

Regards

John

The file radiusclient.h is part of the package ppp (or I
misunderstood your question?).

Not sure either :)

My goal was not to convince anybody, it was just to let you
know that any Slackware user may have a problem to compile
nagios plugins if they have the ppp package installed.  As I
said, the problem was easily solved on my side by
uninstalling ppp and re-installing it after.

Here's the definition of rc_avpair_add() function in the
radiusclient.h file in the ppp package

VALUE_PAIR *rc_avpair_add __P((VALUE_PAIR **, int, void *,
int, int));

and here's the call of rc_avpair_add in check_radius.c

rc_avpair_add (&data.send_pairs, PW_SERVICE_TYPE, &service, 0)

I don't know anything about libradius.  Do you know what is
the *supposed* arguments number for rc_avpair_add()?  If
it's 4, I can send a bug report to Patrick.

The radiusclient.h file is in attach.

hi sebastien,

this looks like a problem with slackware or the slackware
package of ppp then.  where is the radiusclient.h provided
by your libradius package (or whatever the slackware
equivalent is that provides radiusclient.h)?

i'm not sure why installing ppp would plop an include file
used to build ppp in a compiler accessible directory in the
first place, but unless you can provide a convincing reason
why this is a problem with the nagios plugins, i'm going to
close out the bug in a week's time.


thanks,
        sean
