Anyone have problem with PGPlot under Knoppix?

Chah has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

This is my first time using PGPlot. I'm trying to run the examples from various tutorials around the web. For the most part, things tend to work as advertised with Knoppix, and Perl. But I can't seem to get this line to work:

perldl> use PDL::Graphics::PGPLOT;

Can't locate loadable object for module PGPLOT in @INC (@INC contains:
+ /etc/perl /usr/local/lib/perl/5.8.8 /usr/local/share/perl/5.8.8 /usr
+/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /us
+r/local/lib/site_perl .) at /usr/lib/perl5/PDL/Graphics/PGPLOT/Window
+.pm line 2272

I've tried this on several different machines, using Knoppix 5.3.1 and Knoppix 5.1.1. They come back with the same, or similar error. I went to CPAN to try to download and install PGPlot, but when I try this, I get:

$ perl Makefile.PL
Can't locate ExtUtils/F77.pm in @INC (@INC contains: . /etc/perl /usr/
+local/lib/perl/5.8.8 /usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/

+_perl) at Makefile.PL line 11.
BEGIN failed--compilation aborted at Makefile.PL line 11.

I don't know what to make of these errors. Any help?

Thanks,

Hi Chah, It looks like PGPLOT has not been correctly installed. ExtUtils::F77 is a pre-requisite for PGPLOT, so you'll need to install it first. The pgplot C library is another pre-requisite for PGPLOT - so you'll also need to install that before building and installing PGPLOT (the perl module). Cheers, Rob	[reply]

Hi, There has recently been a discussion on PGPLot in the PDL mailing list. As in that case I post my installation notes (ammended with the help of several users of the PDL mailing list) in case you fin them useful useful: download, uncompress and untar in: /usr/local/src create a directory /usr/local/pgplot open the drivers.list file and select drivers copy the drivers.list file to /usr/local/pgplot change directory to /usr/local/pgplot execute the makemake: /usr/local/src/pgplot/makemake /usr/local/src/pgplot linux g77_gcc Now comes the tricky part ... In openSUSE 10.3 modify the make file to point to gfortran: FCOMPL=gfortran FFLAGC=-ffixed-form -ffixed-line-length-none -u -Wall -fPIC -O Also the png driver will not compile if the following line: pndriv.o : ./png.h ./pngconf.h ./zlib.h ./zconf.h is not replaced by: pndriv.o : /usr/include/png.h /usr/include/pngconf.h /usr/include/zlib.h /usr/include/zconf.h # if the drivers.list file includes /(V)GIF, /(V)PPM, or /(V)WD, # the source code for these drivers must be edited. Add these three steps: cd drivers grep -n 64-bit * edit the listed files at the lines specified. make make cpg add to bash.bashrc.local export PGPLOT_DIR=/usr/local/pgplot export PATH=$PATH:/usr/local/pgplot add to ld.conf.so /usr/local/pgplot run ldconfig In the CPAN shell, install the PGPLOT module.
