Installing PGplot with gfortran

Installing PGplot (www.astro.caltech.edu/~tjp/pgplot/) with gfortran

Follow the normal installation procedure:

$ sudo mv pgplot5.2.tar.gz /usr/local/src

$ cd /usr/local/src

$ sudo tar xzvf pgplot5.2.tar.gz

$ sudo mkdir /usr/local/pgplot

$ cd /usr/local/pgplot

$ sudo cp /usr/local/src/pgplot/drivers.list .

Edit the file drivers.list and uncomment (select) the drivers

/NULL (null device),

/PS, /VPS, /CPS, /VCPS (PostScript drivers), and

/XWINDOW, /XSERVE (X window drivers).

Run makemake to prepare the makefile for a Linux system with g77_gcc compiler,

$ sudo /usr/local/src/pgplot/makemake /usr/local/src/pgplot linux g77_gcc

Edit the file makefile and replace lines 25 and 26:

FCOMPL=g77

FFLAGC=-u -Wall -fPIC -O

by the following lines:

FCOMPL=gfortran

FFLAGC=-ffixed-form -ffixed-line-length-none -u -Wall -fPIC -O

Continue the normal installation procedure,

$ sudo make

$ sudo make clean

and, assuming that LD_LIBRARY_PATH points to /usr/local/lib,

$ cd /usr/local/lib

$ sudo ln -s /usr/local/pgplot/libpgplot.so .

Define the environment variable PGPLOT_DIR, pointing to your installation directory. This can be done by adding to your .bashrc or .bash_profile file the lines

# PGplot

export PGPLOT_DIR='/usr/local/pgplot'

Additionally, you can customize PGplot by adding the following lines to your .bashrc or .bash_profile:

# Default xwindow device

export PGPLOT_DEV='/xwin'

# Default white background

export PGPLOT_BACKGROUND='white'

# Default black foreground

export PGPLOT_FOREGROUND='black'

# Marking text written in the ps file so it can be be edited

export PGPLOT_PS_VERBOSE_TEXT='yes'

You may want to have an xwindow with 256 colors, and make the server window not visible. This can be done by starting the pgxwin_server with these options:

# Starting pgxwin_server

/usr/local/pgplot/pgxwin_server -win_maxColors 256 -server_visible False
