Hi all,

As I'm quite new to Linux and Perl I'm having some difficulties now which I'm unable to solve using Google

I'm trying to install the Math::LP::Solve module but to no avail. I first tried installing the Math::LP module by typing:

perl -MCPAN -e 'install Math::LP'

and it warned me about some prerequisites not found on my system and prepended them to the queue.

I confirmed that it should prepend them. But in the end it didn't install correctly. Only modules installed were Math::LinearCombination and Math::SimpleVariable. It ended in something like:

-----------------------------------------
Running make install
 make test had returned bad status, won't install without force
-----------------------------------------

It seemed that the Math::LP::Solve module caused the failure so I tried
installing only the Math::LP::Solve module.

This is the output:

-----------------------------------------

I've tried re-installing RedHat 8.0 but it was exactly the same.

Any help would be appreciated.


That's not going to be a quick one to answer!   I've noted your post and I'll look at it / answer more fully in the next 24 hours

Thanks for the quick response, a search for precompiled versions didn't yield anything either.

Hmmm, I was curious and tried to install it too.

perl -MCPAN -e shell

cpan> install Math::LP

And installed wihtout problems on RH 7.3

Probably not what you wanted to hear, but it's one more variable out the way.

jfp

That would suggest it's RH 8 related. I did install all the available RH 'fixes' so it might be a bug. If all else fails I could always install RH 7 because I do need that module.

I've just had a further chance to look at the original logs, and read the follow ups too ... it looks to me like the underlying problem is not with the CPAN module itself, but with the underlying module that it downloads from ftp://ftp.ics.ele.tue.nl/pub/lp_solve/lp_solve_3.2.tar.gz; as a wild guess there's a problem at the "cpp" - C PreProcessor - level as the system adjusts the source code in C to suit the architecture of the computer that it's running on.

I don't have a RH8 system to hand   ... so I can't start dooing any experiments here;  if I had, I guess I would proceed:
1. Reproduce the problem in RH8
2. Check that there was no problem in RH7 (just in case there's something else different between jfp and duuR's systems)
3. Try to install the lp_solve library outside the CPAN loader (i.e. grab a copy of the file from the dutch site).

Have a look and see if there's a README or INSTALL file in the tar file containing the lp_solve library - tips, techniques, contacts;  it's quite possible that the authors HAVE come across the problem with RH8, but that the automated procedure to install the module that's part of the CPAN doesn't reflect advise and instructions that they have added to their documentation.

Not a "here is how you solve the problem" answer, I'm afraid, but some pointers and ideas that may help you along towards that answer.  Hope it helps - Graham

Maybe I was a bit over enthusiastic when installing RH8.0 and would RH7.* better suit my needs. A friend has RH7.4 or 7.3, I might try and install that.

Copies of the module from outside CPAN had the same results. I have notified the author but no reply as yet.

As soon as I have it fixed I will post a message.

Much appreciated

Alas, no joy...

I installed version 7.3 and it did not install either. This time the error messages are a bit different though.

First I did this:

perl -MCPAN -e 'install Math::LP'

This ended in error messages stating it could not find LP::Solve in @inc.

So I did this:

perl -MCPAN -e 'install Math::LP::Solve'

The author did not reply either so I'm in a bit of a puddle.

Does anyone know what seems to be the problem? I can manually untar stuff so it is installed...

Thanks in advance, I'm about to give in to this...

Results at last! After the error messages I installed the Bundle::CPAN. After that I tried the installation again and it installed without any errors.  

I tried the same with RH 8.0 and that did not help then. So it does seem that the LP package is not yet suitable for RH 8.0. The error messages I got with RH 8.0 where C related I think.

Could one of you tell me what this Bundle::CPAN thingie does, the text is a bit unclear to me.
