[R] Readline problem.

[Rolf Turner]

This question relates, at least vaguely, to recent postings
from me concerning my attempts to build R-1.5.1 under Solaris 2.7.

I've more or less given up on this, and I and a colleague are
attempting to build R-1.5.1 on another machine in our Department,
and are getting a ***different*** problem.

Version details:
platform sparc-sun-solaris2.9
arch     sparc               
os       solaris2.9          
system   sparc, solaris2.9   
status                       
major    1                   
minor    5.1                 
year     2002                
month    06                  
day      17                  
language R

The ``other'' machine is relatively new and is running Solaris 2.9.
It has just had gcc version 3.2 installed on it.  It also has just
had the readline package installed on it.

But when we do ./configure, we get errors of the following form.
(These lines are copied and pasted from config.log):

If we proceed on to ``make'' and ``make check'' everything appears to
go OK, and R-1.5.1 gets made, except that command line editing is not
available.  Naturally, since the readline facility is not working.
(Since readline/command line editing is not available, savehistory()
doesn't work either.)

Can anyone give me any idea as to why we are getting these ``multiply
defined'' symbols, and what we can do about it?  Please be as
simplistic as you can!  The intricacies of compilers and ld are
pretty mysterious to us.

As far as we can discern, gcc and readline were installed in a
completely standard way, so we have no idea why these hiccups
are occurring.

Thanks for any advice/wisdom/insight that anyone can give.

				cheers,
