[Help-gsl] unreferenced libraries

[Paul Gomez]

 Hi people!

I´m working in a code with a friend! Both employ
Linux<http://www.daniweb.com/forums/thread95089.html#>Platforms, but
he works in Suse, and I´m working in Kubuntu.

Both distributions suppose to work with the GNU/Linux libraries.

We work the code on his machine with
Suse<http://www.daniweb.com/forums/thread95089.html#>.
And runs perfectly well!

But in my Kubuntu´s machine doesn´t run well. At the beggining there was a
lot of missing files, but we copy all from the include, lib, sys of his
laptop <http://www.daniweb.com/forums/thread95089.html#>, and then the
compiler founds all the files. Create the executable both still couldn´t
work. This was the problem (I think this is fixed).

See `config.log' for more details.

I made this installation of the needed libraries (is a new installation of
Linux in this pc)! Now it looks it can understand the gsl references.
Yesterday I already had this problem previous to the -lm problem! I copy the
gsl files on the folder include. And that problem dissapear. Now it´s back!
Could you explain a little in detail what the different lines in the quote
means, so, I can understand better!  And what I can do??

Thanx for your help
