- Appendix F. PGPLOT Installation Instructions
-
- Version 5.1.0.
-
- To install PGPLOT, you need to perform the following steps. These steps are
- described more fully below.
-
- 1. Copy the distribution file by anonymous ftp from Caltech.
- 2. Unpack the distribution file to create the ``PGPLOT distribution''
- directory tree. This is identical for all implementations of PGPLOT and
- can be placed on any disk that is visible on the target system,
- including read-only network-mounted disks.
- 3. Create a writeable directory in which the PGPLOT library and associated
- files will be created. One such directory is needed for each different
- operating system and compiler combination (``target system'') that you
- wish to support. This should not be the same directory as the directory
- containing the source code.
- 4. Configure PGPLOT by selecting device drivers from the available list.
- 5. For supported operating systems, execute the supplied script to create
- the library and demonstration programs.
- 6. Run the demonstration programs on your selected devices and verify that
- they run satisfactorily.
- 7. Optionally, install and test the C binding and/or Motif driver. This
- requires an ANSI C compiler (that understands function prototypes) and
- is not available on all systems.
-
- Step 1: Copy the distribution file
-
- Copy the distribution file by anonymous ftp from Caltech. Use anonymous ftp
- (user: anonymous, password: your id username@machine) to node
- astro.caltech.edu (131.215.240.1).
-
- The distribution file is a UNIX tar file compressed with Gzip. Issue the
- following ftp commands to retrieve the file:
-
-
- cd pub/pgplot
- binary
-
- To get the PGPLOT distribution:
-
- get pgplot5.1.tar.gz
-
- Step 2: Decompress the files
-
- UNIX systems:
-
- Use Gunzip and tar to decompress the archive and extract its contents. This
- will create directory pgplot (and subdirectories) in the current directory.
- Make sure that your current directory is where you want to create the
- ``PGPLOT distribution'' directory tree.
-
- gunzip -c pgplot5.1.tar.gz | tar xvof -
-
- VMS systems:
-
- You will need two programs to decompress and extract the contents of the
- distribution file: gunzip and vmstar. These programs are not part of VMS,
- but are widely available on the Internet. Use gunzip to decompress the
- distribution file, e.g.,
-
- $ gunzip pgplot.targz
-
- (Substitute the name of the file that you copied in the ftp step). Then use
- vmstar to extract the contents of the archive:
-
- $ vmstar/extract/verbose pgplot.tar
-
- This will create a subdirectory [.PGPLOT] (and lower-level subdirectories)
- in the current directory. Make sure that your current directory is where you
- want to create the ``PGPLOT distribution'' directory tree.
-
- Step 3: Create the target directory
-
- Create a writeable directory in which the PGPLOT library and associated
- files will be created. One such directory is needed for each different
- operating system and compiler combination (``target system'') that you wish
- to support, e.g.,
-
- UNIX: mkdir /usr/local/pgplot
- VMS: create/directory USR:[LOCAL.PGPLOT]
-
- Do not try to create the PGPLOT library in the source directory.
-
- Step 4: Select device drivers
-
- Configure PGPLOT by selecting device drivers from the available list. First
- copy the file drivers.list from the distribution directory to the target
- directory, and then use a text editor to select device drivers. This file
- contains one line for each available device driver: delete the exclamation
- mark (!) at the beginning of the line to include the driver, or ensure that
- an exclamation mark is present if you want to exclude the driver. Many of
- the drivers can be used only on certain operating systems (see notes in
- drivers.list), so include only the drivers you plan to use. PGPLOT can later
- be reconfigured by restarting the installation at this step. Most
- installations should include: the null device (/NULL), PostScript printers
- (/PS, /VPS, /CPS, and /VCPS), Tektronix terminals (/TEK, /XTERM, and
- possibly other variants), and, if the X window system is available on the
- target, the X window drivers (/XWIN, /XSERV). You may also wish to include
- drivers for GIF files (/GIF, /VGIF) or some of the other printers.
-
- UNIX: cd /usr/local/pgplot
- cp /root/pgplot/drivers.list .
- vi drivers.list (or use your preferred editor)
-
- VMS: set default usr:[local.pgplot]
- copy root:[pgplot]drivers.list []
- edit drivers.list
-
- The PGPLOT distribution directory is here called /root/pgplot or
- root:[pgplot] by way of example.
-
- Step 5 (UNIX systems): Compile the library
-
- If your UNIX system is not one of the supported systems, see Porting PGPLOT,
- or consult tjp@astro.caltech.edu. If your system is supported, proceed as
- follows:
-
- 1. Make the target directory your current default directory, e.g.,
-
- cd /usr/local/pgplot
-
- 2. Execute the script makemake from the distribution directory: e.g.,
-
- /root/pgplot/makemake /root/pgplot sun4
-
- The first argument supplied to makemake is the name of the distribution
- directory.
-
- The second argument is the name of the operating system; if you omit it
- or supply an unrecognized name, makemake will indicate the allowed
- values (currently these include: aix alliant convex cray freebsd hp
- irix linux next osf1 sol2 sun4 ultrix vp2200).
-
- On some operating systems, where more than one Fortran or C compiler is
- available, a third argument is required; usually this is composed of
- the two compiler names separated by an underscore. If you omit it,
- makemake will indicate the allowed values. Note that you need both a
- Fortran compiler and a C compiler to install PGPLOT.
-
- Once you have supplied valid arguments, makemake may complain that it
- can't find the drivers.list file. Go back to step 4!
-
- 3. The script makemake generates a file makefile for subsequent use, a
- Fortran file grexec.f that calls the selected device drivers, and a
- text file rgb.txt that contains color definitions for use by routine
- PGSCRN. (If you already have a file rgb.txt, possibly modified with
- your own custom definitions, makemake does not modify it.) So at this
- stage you will have at least the following files:
-
- drivers.list
- grexec.f
- makefile
- rgb.txt
-
- 4. Now use the UNIX make command to compile the PGPLOT library following
- the instructions in makefile:
-
- make
-
- By default, make will generate: an object-module library, libpgplot.a;
- a shareable library (if possible on the selected operating system), the
- binary PGPLOT font file grfont.dat, the demonstration programs pgdemo*,
- and a documentation file pgplot.doc. In addition, if the /XWIN and/or
- /XSERV driver was selected in step 4, it will generate a program
- pgxwin_server, and if the /XDISP driver was selected, it will generate
- a program pgdisp.
-
- If this step proceeds satisfactorily, you may want to type
-
- make clean
-
- to remove unneeded intermediate files. You will then have the following
- files in the current directory:
-
- drivers.list
- grexec.f
- grfont.dat (binary font file)*
- libpgplot.a (PGPLOT library)*
- libpgplot.so (shared library, optional)*
- makefile
- pgdemo1 ... pgdemo14 (demonstration programs)
- pgdisp (required by /XDISP driver)*
- pgplot.doc (ASCII documentation file)
- pgxwin_server (required by /XWIN driver)*
- rgb.txt (color name database)*
-
- If you want to copy the compiled version of PGPLOT to another
- directory, you must copy at least the files marked with an asterisk
- (*). The documentation file contains the PGPLOT subroutine
- descriptions, which are also available in the manual.
-
- Solaris 2.x users should define environment variable LD_LIBRARY_PATH (a
- list of directories) to include the directory that contains the PGPLOT
- shared library.
-
- 5. A documentation file in HTML format that can be displayed with Mosaic,
- Lynx, Netscape or another HTML reader can be created by typing:
-
- make pgplot.html
-
- This file is created by executing a perl program to extract the
- documentation from the source code. If you do not have perl installed
- on your system, you can access the file on the WWW at
- http://astro.caltech.edu/~tjp/pgplot/subroutines.html. You may need to
- edit the first line of file pgplot/makehtml to include the correct
- commands for invoking perl on your system.
-
- 6. A documentation file in LaTeX format (Appendix A of the manual) can be
- created by typing
-
- make pgplot-routines.tex
-
- This file is also created by executing a perl program to extract the
- documentation from the source code. You may need to edit the first line
- of file pgplot/maketex to include the correct commands for invoking
- perl on your system. To print this file, you will need to run LaTeX to
- create a dvi file and a dvi interpreter to print it, e.g. (on Unix
- systems)
-
- latex pgplot-routines
- dvips pgplot-routines -o
-
- Step 5 (VMS systems): Compile the library
-
- 1. Make the target directory your current default directory, e.g.,
-
- set default USR:[LOCAL.PGPLOT]
-
- 2. Don't forget to first copy DRIVERS.LIST into the target directory and
- edit it to indicate which drivers are to be included in the PGPLOT
- installation.
-
- 3. Execute the script install.com from the VMS subdirectory of the
- distribution directory, e.g.:
-
- @root:[pgplot.sys_vms]install root:[pgplot]
-
- The first argument supplied to install is the name of the distribution
- directory.
-
- The install script issues messages as it proceeds: it usually takes
- quite a long time. It should generate the following files:
-
- DRIVERS.LIST
- GREXEC.F
- GRFONT.DAT
- GRPCKG.OLB
- GRPSHR.EXE
- GRPSHR.OLB
- PGDEMO1.EXE ... PGDEMO14.EXE
- PGXWIN_SERVER.EXE
- RGB.TXT
-
- The script assumes that you have the current DEC Fortran and C
- compilers installed. A C compiler is required for XWDRIV and X2DRIV and
- the associated programs PGXWIN_SERVER and PGDISP, and for generating
- the C wrapper library CPGPLOT.OLB. If you don't have the DEC C
- compiler, the script will have to be modified.
-
- The script may fail if you redefine any of the common DCL commands like
- PURGE or DELETE.
-
- 4. To install the PGDISP program (optional, required if you selected the
- /XDISP device driver):
-
- @root:[pgplot.sys_vms]install root:[pgplot] PGDISP
-
- This adds one file, PGDISP.EXE. The PGDISP program sometimes gives
- compilation problems. Most of these are non-fatal warnings that can be
- ignored.
-
- 5. Unlike the UNIX installation procedure, the VMS installation procedure
- does not generate documentation. A list of subroutine synopses in VMS
- help format is available by anonymous ftp from
- ftp://astro.caltech.edu/pub/pgplot/pgplot.hlp. This file can be
- inserted in a help library with a DCL command like
-
- $ library/insert/help pgplot.hlb pgplot.hlp
-
- Step 6: Run the demonstration programs
-
- Run the demonstration programs on your selected devices and verify that they
- run satisfactorily.
-
- Before running any PGPLOT program, you must ensure that the environment
- variable PGPLOT_DIR is correctly defined. This is the name of the directory
- in which PGPLOT will look for the files grfont.dat and rgb.txt (unless
- environment variables PGPLOT_FONT and PGPLOT_RGB are defined to override
- this default behavior), and, if needed, the X-window server program
- pgxwin_server:
-
- UNIX csh: setenv PGPLOT_DIR /usr/local/pgplot/
- UNIX sh: PGPLOT_DIR="/usr/local/pgplot/"; export PGPLOT_DIR
- VMS dcl: define PGPLOT_DIR usr:[local.pgplot]
-
- It is also convenient, but not essential, to define a default PGPLOT device
- with environment variable PGPLOT_DEV, e.g.
-
- UNIX csh: setenv PGPLOT_DEV /xwin
-
- Other PGPLOT environment variables are described in the manual.
-
- When using a UNIX shared library, you may also need to put the PGPLOT
- directory in your loader search path, defined in environment variable
- LD_LIBRARY_PATH.
-
- To run a program in UNIX, type its name (with directory if the current
- directory is not in your path):
-
- ./pgdemo1
-
- To run a program in VMS, use the RUN command:
-
- run pgdemo1
-
- All the demonstration programs prompt for a device name and type. Type a
- question mark ? to see a list of the available device types and verify that
- PGPLOT has been configured properly.
-
- Points to check for: the PGPLOT program correctly reads the font file and
- displays superscripts, subscripts and special characters (pgdemo2); the
- PGPLOT program can read the color database (pgdemo10); on interactive
- devices, the cursor works correctly (pgdemo5, pgdemo6).
-
- Step 7: Install the C binding
-
- Optionally, install and test the C binding for PGPLOT. This requires an ANSI
- C compiler (that understands function prototypes) and is not available on
- all systems.
-
- UNIX: make cpg
-
- This creates three files:
-
- cpgplot.h (ANSI C header file)
- libcpgplot.a (library containing the C binding)
- cpgdemo (demonstration program)
-
- VMS: @root:[pgplot.sys_vms]install root:[pgplot] CPG
-
- This creates three files:
-
- CPGPLOT.H (ANSI C header file)
- CPGPLOT.OLB (library containing the C binding)
- CPGDEMO.EXE (demonstration program)
-
- To test, run cpgdemo in the same way as the other demonstration programs.
-
- Step 8: Install the Motif support and example files [optional]
-
- Available only in PGPLOT v5.1 and later versions.
-
- If you plan to develop Motif applications that use the PGPLOT widget, or if
- you want to inspect a sample Motif application, you will need to do this
- step. You must first: (a) ensure that the Motif header files and libraries
- are installed on your system; (b) select XMDRIV in drivers.list before
- installing the PGPLOT library [step 4]; and (c) install the C binding [step
- 7].
-
- UNIX
-
- In Unix installations, the Motif support files and demonstration program are
- automatically installed by make if you have selected XMDRIV in drivers.lis
- before running makemake, and if Motif is installed on your system. The
- following files are installed:
-
- pgmdemo (executable demo program)
- libXmPgplot.a (object library required by PGPLOT/Motif applications)
- XmPgplot.h (header file required by PGPLOT/Motif applications)
-
- To test, run pgmdemo in the same way as the other demonstration programs.
- You must first ensure that an X-window display is available and that
- environment variable PGPLOT_DIR is correctly defined.
-
- VMS
-
- Execute the folliwing command:
-
- @root:[pgplot.sys_vms]install root:[pgplot] PGMDEMO
-
- This creates five files:
-
- PGMDEMO.EXE (executable demo program)
- PGMOTIF.OPT (linker options file for linking PGPLOT/Motif applications)
- PGXWIN.OBJ (object module required by PGPLOT/Motif applications)
- XMPGPLOT.OBJ (object module required by PGPLOT/Motif applications)
- XMPGPLOT.H (header file required by PGPLOT/Motif applications)
-
- To test, run PGMDEMO in the same way as the other demonstration programs.
- You must first ensure that an X-window display is available (use
- CREATE/DISPLAY if necessary) and that logical name PGPLOT_DIR is correctly
- defined.
-
- (This step may not work on all VMS systems: there are many differences
- between the various available versions of the DEC C compiler and DECwindows
- Motif. If you get error messages, you may need to modify file
- [pgplot.sysvms]make_pgmdemo.com.)
