This file explains how to install the GNU plotutils (plotting utilities)
package. The file README summarizes the contents of the package. Please
send bug reports to <[email protected]>, and suggestions for
longer-range improvements to both <[email protected]> and the principal
author and current maintainer, Robert S. Maier <[email protected]>.
These are package-specific installation instructions: PLEASE READ THEM.
Before reading them, you should glance through the generic installation
instructions in the file INSTALL. The instructions in that file may be
summed up as follows. You build a GNU package by typing `./configure' and
then `make'. After building, you may run validation tests on the package
by typing `make check'. To install the package, you type `make install'.
A documentation file, in `info' format, is installed as part of this
process. You may produce a copy of the documentation for the package, in
dvi format, by typing `make dvi'. This assumes that you have the TeX
document formatter installed.
The most important points not mentioned in the file INSTALL are these.
**********************************************************************
If you have a working C++ compiler and would like to build the
`libplotter' class library and the pic2plot utility, both of which are
written in C++, you should add the `--enable-libplotter' option to the
`./configure' command.
**********************************************************************
**********************************************************************
By default, if the `libpng' library and its header file are found at
installation time, then support for PNG graphics will be included in
libplot and all command-line utilities. If for any reason you wish to
omit PNG support despite libpng being present, you should add the
`--without-libpng' option to the `./configure' command.
**********************************************************************
**********************************************************************
It is not unknown for one or more of the validation tests that are run
by doing `make check' to fail for harmless reasons. See B.6, below.
**********************************************************************
**********************************************************************
If you would like to build and a standalone version of the `libxmi'
2D rasterization library, and install the library and its documentation,
you should add the `--enable-libxmi' option to the `./configure'
command. This is not done by default because libxmi is also distributed
as a separate package.
**********************************************************************
The rest of this file discusses possible installation problems. There are
some additional options that you can add to the `./configure' command.
They are mentioned too, in passing.
----------------------------------------------------------------------
Possible problems not mentioned in the INSTALL file are summarized in the
following three sections. They cover:
(A) Problems related to building the GNU libplot graphics library.
(B) Miscellaneous problems.
(C) Problems related to support for the X Window System.
----------------------------------------------------------------------
A. This section covers problems related to building both the unshared
version and the shared version of the GNU libplot graphics library. Except
on older systems, GNU libplot will normally be built as both an unshared
library and a shared library. A script called `libtool' is used for this.
By default, the application programs `graph', `plot', `tek2plot', and
`plotfont' will be configured to use the shared library.
If for any reason you wish to disable support for the shared version of
libplot, you may begin by doing `./configure --disable-shared' instead of
`./configure'.
----------------------------------------------------------------------
B. This section covers miscellaneous installation problems.
B.1. On some systems, there are potential minor problems having to do with
installing (rather than building) the shared version of libplot. By
default, it is installed in `/usr/local/lib'. On some systems you may need
to run a command (such as `ldconfig'), or even reboot, to let your system
know that a new shared library has been installed. On some systems you may
need to add `/usr/local/lib' to your LD_LIBRARY_PATH environment variable
in order to use the `graph', `plot', `tek2plot', `plotfont', and `pic2plot'
programs after they have been installed. You will be cautioned about
problems of this sort, if any, at installation time.
B.2. If you have a recent laser printer that can use the 35 standard
Postscript fonts even when in PCL 5 or HP-GL/2 mode, such as a 2100-series,
4000-series, or 8000-series HP LaserJet, you may wish to add the
`--enable-ps-fonts-in-pcl' option to `./configure'. No additional actions
on your part, such as installing fonts, are required, since the Postscript
fonts, if present, are internal to the printer.
*** It is recommended that you add this option, since it is innocuous. ***
B.3. By default, the standard 45 `HP LaserJet' fonts, such as Arial,
Univers, etc., which are built into recent HP LaserJets, are available to
the plotting utilities when you produce PCL 5 or HP-GL/2 output, e.g., when
you do `graph -T pcl' or `graph -T hpgl'.
But there are many Postscript viewers that can display these fonts; and
also, in modern LaserJets, which understand both Postscript and PCL, the
fonts are available on the Postscript side as well as the PCL side. Hence,
you may wish to have these 45 fonts available when you produce Postscript
output. To arrange this, you would add the `--enable-lj-fonts-in-ps'
option to `./configure'.
*** It is recommended that you add this option, since it is innocuous. ***
Of course you may well need to acquire the 45 fonts and install them, so
that your Postscript previewer will be able to use them. This is fairly
easy. Instructions are in the file INSTALL.fonts.
You may also wish to add these 45 fonts to your X Window System display, so
that, e.g., when you use `graph -T X', you will be able to use them. This
is possible (instructions are in the file INSTALL.fonts). To make these
fonts available when producing X output, e.g., by `graph -T X', you would
add the `--enable-lj-fonts-in-x' option to `./configure'.
*** It is recommended that you add this option, since it is innocuous. ***
B.4. As part of the installation process, the header file ./include/plot.h
will be installed in a place on your system where the gcc C compiler will
find it. If you wish to use cc as well as (or instead of) gcc, you should
copy plot.h manually to the directory `/usr/include', where cc will find
it. plot.h is not installed in `/usr/include' by default, since many
administrators prefer not to add files to that directory.
B.5. If you are installing this package with DJGPP under MS-DOS, the very
first thing you should do is rename the file `install-sh' in this directory
to `install.sh'. That is on account of filename length limitations in
MS-DOS. If `./configure' reports that it is unable to find certain
executable programs that it should in fact find, you may also need to
replace many of the occurrences of `test -f' in `./configure' and
`./ltmain' by `test -x' (to compensate for the ".exe" extension that MS-DOS
uses). These potential problems are reported by Michel de Ruiter
<[email protected]>. Please contact him for additional information on
MS-DOS installations.
B.6. It is not at all unusual for one or more of the validation tests
performed by doing `make check' to fail on account of innocuous differences
in formatting floating-point numbers, or differences in the rounding of
floating-point numbers. In particular, the `plot2fig' validation test may
fail if you are installing with DJGPP under MS-DOS, or if you are
installing the package on an old NeXT machine.
To emphasize: the failure of two or three of the validation tests, in
particular the `plot2fig' test, is almost certainly quite harmless. But if
a large number of the validation tests should fail, please report it to
<[email protected]>. For some additional remarks on the validation
tests, see the file ./test/README.
----------------------------------------------------------------------
C. This section covers installation problems related to the X Window
System. If for any reason you wish to omit the X Window System support,
you may begin by doing `./configure --without-x' instead of `./configure'.
C.1. To make maximum use of the X support in this package, you will need to
have the 35 standard Postscript fonts installed on your X server. For
instructions on installing Type 1 versions of these fonts, clones of which
are included in the package, see the file ./INSTALL.fonts.
C.2. There is a possible installation problem having to do with X widget
sets. By default, this package uses the free Athena widgets, which are
provided on most but not all machines. Some machines provide Motif widgets
instead of Athena widgets. On such machines (e.g. Hewlett-Packard systems
running HP/UX, and some IBM systems) you should normally begin by doing
`./configure --with-motif' instead of just `./configure', to ensure that
the software is configured correctly.
The only advantage of using Motif widgets, which are not free, is that you
may be able to use Motif's drag-and-drop facility to drag graphics out of
popped-up X Windows, e.g., the window popped up by `graph -T X'.
C.3 On a few machines, the auto-configuration process may not be able to
find the library files containing the X widgets (whether Athena or Motif),
or the corresponding header files. If this problem occurs, you can specify
their location manually at configure time, as follows.
C.3a. If you have the Athena widgets and wish to use them, even though the
auto-configuration process does not find them, you may specify their
location by doing `./configure --with-athena=DIR' instead of just
`./configure'. Here DIR should be a directory whose subdirectory `lib'
contains the Athena widget library files libXaw and libXmu, and whose
subdirectory `include' contains the Athena header files, such as
X11/Xaw/Label.h.
An example would be old Hewlett-Packard systems running HP/UX 10.xx. If
you are installing the package on such a system, you should check whether
the directories /usr/contrib/X11R6/{lib,include} exist. If so, you can use
the Athena widgets. To use them, you would do
./configure --with-athena=/usr/contrib/X11R6
instead of just `./configure'. If these directories do not exist on your
system, you do not have the Athena widgets: you must use `--with-motif'
instead.
Extremely old HP/UX 10.xx systems may have X11R5 instead of X11R6, in which
case you should modify the directory name appropriately.
C.3.b. It is also possible that you have only Motif widgets, but the
autoconfigure process is unable to find the Motif files. In such a
situation, you may specify the location of the Motif files by doing
`./configure --with-motif=DIR' instead of just `./configure'. Here DIR
should be a directory whose subdirectory `lib' contains the Motif widget
library file libXm, and whose subdirectory `include' contains the Motif
header files, such as X11/Xm/Label.h.
C.3.c. There are a very few systems where the widget files must be
specified manually by an even more complicated procedure. An example would
be truly ancient Hewlett-Packard systems that are running HP/UX 9.xx or
earlier. They have Motif widgets, but the Motif files are stored in
unusual places. If you have an HP/UX 9.xx system that X11R6 was installed
on, besides doing `./configure' (or possibly `./configure --with-motif'),
you may need to do
make CFLAGS="-O -I/usr/include/Motif1.2 -L/usr/lib/Motif1.2"
rather than just `make'.
You should note, however, that for HP/UX 9.xx systems, X11R6, presumably
including the Athena widgets and not the Motif widgets, was available as a
patch. If you have an HP/UX 9.xx system that the X11R6 patch was installed
on, you can probably do `./configure --with-athena=/usr/contrib/X11R6'.
C.4. Some version of Motif require that executables that are linked with
Motif be linked, also, with the `libXpm' library. `configure' knows about
this. But if for some reason it is unable to find libXpm and the
corresponding header file, you can specify their location manually at
configuration time, by doing not just `./configure --with-motif', but
rather `./configure --with-motif --with-libxpm=DIR'. Here DIR should be a
directory whose subdirectory `lib' contains libXpm, and whose subdirectory
`include' contains the corresponding header file, X11/xpm.h.
