[R] Fortran linking problems

[Angel Lopez-Urrutia]

Thanks to all,
Once I installed readline-dev (and reinstalled Blas/lapack) it worked!
I don't know it why this wasn't shown as a dependency when I installed the R 
rpm!
Thanks,
Gelu

Did you build R yourself, or install an rpm?  It looks like your
installation is missing libreadline, and it was there when R was built.
I'm surprised then that R would run, but maybe it is somewhere that the
standard LD_LIBRARY_PATH does not find.

You need readline and perhaps readline-devel (if it exists)
installed, and they should have been dependencies of the R rpm (if that
is what you used).

I believe that -lreadline is not needed (and this is solved in R-devel),
so you could just edit R_HOME/etc/Makeconf and remove -lreadline (and
-lnurses) from FLIBS.

In cases like that, look in config.log.  The error message is terse,
because it is repeating a test done when R was installed.
