You will need -lgfortran at the link stage when you build PGPLOT - not
the Perl module, but rather the base library. I just built it today and
here is what I ended up putting in the makefile
SHARED_LIB_LIBS=-lX11 -lpng -lz -lgfortran

Hi,
I'm having trouble getting the Perl PGPLOT module going.
I have Perl 5.14 installed.
I have installed the PGPLOT c libs, v5.2 and
the examples work fine for the c examples.
I next went to install the Perl module PGPLOT-2.21
It all built and installed fine, but when I try to run the
Perl examples I get the error:
############################################
$$ perl test1.p
Testing simple point plot...
PGPLOT module version 2.21
perl: symbol lookup error: /usr/local/pgplot/libpgplot.so: undefined symbol:
_gfortran_concat_string
############################################
I tried to alter the Makefile.Pl to use a generic g77 with
use ExtUtils::F77 qw(generic g77) ;
but I still get the same error.
Any clues as to how to fix this? Google is full of links for
"undefined symbol: _gfortran_concat_string"
and havn't found a useful answer.
Thanks,
zentara
