Re: [Perlgssapi-developer] [rt.cpan.org #48732] look for krb5-config in /usr/kerberos/bin

[Achim G. <ac...@gr...>]

Hello Mark,

if you run the the "perl Makefile.PL" in this way:

perl Makefile.PL --gssapiimpl /usr/kerberos

You can always specify the path where to look for
krb5_config utility. (run "perl Makefile.PL --help" for all available 
options).

In general the GSSAPI-Makefile.PL does not look into the PATH environment,
it makes direct use of the systems /usr/bin/which for searching for 
krb5-config and it's path.

From that point of view I suppose if you can make your sudo-toolchain properly
run the "which krb5-config" the other parts will work fine.

Does this help on your problem?

Best Regards,
Achim

Hello Mark,

As far as I know there is no '"system standard" place for `krb5-config'.
So the "which krb5-config"-way was choosed because this works on the most
platforms, Kerberos-implementions (MIT, Heimdal, Sun) and conditions.
The idea was to keep the Makefile.PL's complexity small.
But you're correct, on the circumstances you describe the Makefile.PL
behaves 'broken'.

Your suggestion how Makefile.PL should additonally search the
'"system standard" place for `krb5-config`' is... to test
a given list of binaries.

If I got the idea right that means maintaining a list of 
paths to search for the krb5-config binary within Makefile.PL?

What's the output of

perl -e "print $^O; "

on your platform?

(Sorry I can't provide a patch within the next days... you will get my answer
at the end of this week)

Achim

Hello Mark,

I've modified the Makefile.PL as discussed.
Find the new Makefile.PL attached to this email.

Please check if the new Makefile.PL works within your toolchain.
Please let me know if that works.
Please let me know if there are any problems.

Best Regards,
Achim

Hmm... maybe I did the testing the wrong way?

1. I've additionally added the Makefile.PL Version information to the Build 
output, thanks for the idea.

2. Find below the manual step-by-steps executed I have executed on my platform

3. Please check if this test steps work on your platform
   by manual executing

4. If they work... please let me know an idea what makes the difference
   between manual stepping and your build environment.

Thank you!
