[Perlgssapi-users] krb5-config not found

[simon <l0c...@go...>]

Hello,

I want to compile the GSSAPI perl module on Ubuntu 6.10 as I want to
use Net::Jabber/ Net::XMPP

All I get is this error from the cpan shell:

Searching krb5-config command... not found! at Makefile.PL line 94.
Warning: No success on command[/usr/bin/perl Makefile.PL INSTALLDIRS=site]
CPAN: YAML loaded ok (v0.62)
Failed during this command:
 AGROLMS/GSSAPI-0.24.tar.gz                   : writemakefile NO
'/usr/bin/perl Makefile.PL INSTALLDIRS=site' returned status 256

whereis krb5-config returns:

krb5-config: /usr/bin/krb5-config /usr/X11R6/bin/krb5-config
/usr/bin/X11/krb5-config

What can I do to make this compile, please?

I've googled this and no reply so I really hope someone on this list can help.

Thanks

S.

Hello,

thanks for such a speedy reply! your help is much appreciated and has
solved my immediate problem.

But my first email was not clear, sorry.

I needed GSSAPI to compile Authen::SASL module NOT Net::Jabber or Net::XMPP

(Net::Jabber and Net::XMPP require Authen::SASL)

I can now compile Authen::SASL thanks to your suggestion to use: perl
Makefile.PL  --gssapiimpl /usr on GSSAPI

Thanks a million.

S.

OK. There is a *optional* dependency in 
Authen::SASL::Perl:GSSAPI to GSSAPI.pm.

But you really need GSSAPI.pm only
if you want to make a real use (do you?) of 
Authen::SASL::Perl:GSSAPI (To use Kerberos based
Authentication for example).

In any other case you don't need to install GSSAPI.pm
if Authen::SASL is just a dependency.

I suspect the script is ending up with find_krb5config_cmd() returning
"/usr/bin/krb5-config /usr/X11R6/bin/krb5-config".
I am suspicious about how predictable the output of which is. You could
probably write your own which() function in perl?

I am unsure.
Simon, can you help me and send back the output
of your run of

which krb5-config

please?

Maybe, yes.
Is there portable vode in CPAN available 
(I have searched, but maybe not searched in the right way)
that does a which() and works fine 
on all Platforms supported by MIT Kerberos/Heimdal/others?

Any ideas how to implement this in a portable and reliable
way are welcome!

Hello,

nothing is returned from:

which krb5-config

even though

whereis krb5-config returns:

krb5-config: /usr/bin/krb5-config /usr/X11R6/bin/krb5-config
/usr/bin/X11/krb5-config

OK. Maybe me understanding of how 'which' works or should work
ist wrong.
My idea was that 'which krb5-config' locates the absolute path of
krb5-config if this executeable can be found in $PATH.

Simon, '/usr/bin/' is a member of your PATH environment?

If my understanding of 'which' is wrong - can someone
more experienced can help me and explain what's wrong
with my understanding?

Thank you,
Achim

I'm no expert, but which/whereis have always bitten me in painful ways
when I used them in my .profile/startup scripts. You can't rely on the
platform from giving you something consistent. But, something simple in
Makefile.PL could work and be reliable. Like this:

sub which {
    my $prog = shift;
    for (split(/:/,$ENV{'PATH'})) {
        my $fullpath = "$_/$prog";
        return $fullpath if -x $fullpath and -f $fullpath;
    }
    return undef;
}

(Although this code is broken if $PATH contains a double colon or ends
with a colon.)

This errormessage means the Makefile.PL can not find the
'krb5-config' provided by your Kerberossystem.

The Makefile.PL makes use of a backticked 'which'

$r = `which krb5-config 2>/dev/null`;

to find the krb5-config command.

What happens if you key in

which krb5-config
to your shell?

In any case an explicit

perl Makefile.PL  --gssapiimpl /usr

should work if your krb5-config ist

/usr/bin/krb5-config

Please let me know if this works for you!

BTW: Net::Jabber/ Net::XMPP
are making use of GSSAPI.pm or depend on it?
