Installing with CPAN on Cygwin
=================================================================
If you already have a full cygwin install on your PC, the
simplest way to get a basic PDL is to use the cpan shell.
This will get you all the functionality that is supported
by existing cygwin package functionality (i.e. available
from the standard Setup.exe installs).
!! NOTE: you will be asked to answer some configuration
!! questions the first time you use cpan on your system.
!! Most should be self-explanatory.
Just start up an xterm and run cpan from the bash prompt:
bash$ cpan
cpan> install PDL
This should pull in installs of
Astro::FITS::Header
Data::Dumper
File::Spec
Filter::Util::Call
Text::Balanced
Inline
if they are not already installed or of a recent enough version.
This should finish with a PDL with the following functionality:
- base PDL modules
- PDL::IO::GD
- PDL::GIS::Proj
- PDL::Graphics::TriD
- PDL::GSL::*
- PDL::Slatec
- PDL::Transform::Proj4
=================================================================
Manual Configuration and Install
=================================================================
In general, the standard install process for perl modules
should work on cygwin. If you don't want to accept the
default build options for PDL, edit the perldl.conf file.
You'll find that file in the top level PDL folder/directory.
The remaining PDL functionality depends on external libraries
and packages that must be pre-installed before installing PDL.
If you want to use other modules with external dependencies
not available through the Setup.exe from http://www.cygwin.com
then you'll need to get, build, and install the desired
libraries yourself (see the HOW-TO notes below).
The manual configure/build/install process is:
Edit the PDL/perldl.conf file as desired
From the bash$ prompt in the top level PDL/ directory:
perl Makefile.PL # configures all the Makefile
make # builds/compiles everything
make test # run test suite
make doctest # builds online documentation
# and html docs
If any tests fail (rather than skipped) you can run them
by hand for more detailed diagnostic messages. For
example:
perl -Mblib t/plplot.t
1..27
ok 1 - use PDL::Graphics::PLplot;
# Looks like you planned 27 tests but only ran 1.
perl -Mblib t/proj_transform.t
1..4
# Looks like your test died before it could output anything.
These test failures with the number of planned tests not
equal to the number of tests run (1) or if a test died
before it could output anything indicate a problem with
the DLL base addresses. See the instructions for REBASEALL
below.
If PDL built ok and passed tests, you can test the interactive
PDL shell before actually installing PDL by running from the
PDL/ top level directory:
perl -Mblib perldl # quit to exit the PDL shell
To finally install the PDL into your system run:
make install
=================================================================
FFTW
=================================================================
!! You'll need to build *version 2* of the FFTW library for PDL.
!! Version 3 has a new API and is not compatible with this PDL.
# download the source code if needed, I used wget
wget http://www.fftw.org/fftw-2.1.5.tar.gz
# extract the source files
tar xzf fftw-2.1.5.tar.gz
# change to the source directory
cd fftw-2.1.5/
# this is the standard GNU build process
./configure
make
make check
make install
The FFTW library built without a hitch and installed in
/usr/local as the default (/usr/local/lib, /usr/local/include,
and /usr/local/info). A clean build of PDL should pick it up.
NOTE: if problems see rebaseall below.
=================================================================
PGPLOT
=================================================================
1. build the pgplot library and install.
Download from http://astro.caltech.edu/~tjp/pgplot
# Extract the archive file into a source location, I used ~
$ tar xzf pgplot5.2.tar.gz
$ cd ~/pgplot
# Make an install directory, this is a typical default location
$ mkdir /usr/local/pgplot
$ cp drivers.list /usr/local/pgplot/
$ cd /usr/local/pgplot
$ vi drivers.list
Edit drivers.list to enable the drivers you wish but
uncommenting desired drivers by removing the leading ! on the
line. Here are the ones I used (see PDL/cygwin/driver.list):
$ grep -v '^!' drivers.list
LXDRIV 0 /LATEX LaTeX picture environment
NUDRIV 0 /NULL Null device (no output) Std F77
PPDRIV 1 /PPM Portable Pixel Map file, landscape
PPDRIV 2 /VPPM Portable PIxel Map file, portrait
PSDRIV 1 /PS PostScript printers, monochrome, landscape Std F77
PSDRIV 2 /VPS Postscript printers, monochrome, portrait Std F77
PSDRIV 3 /CPS PostScript printers, color, landscape Std F77
PSDRIV 4 /VCPS PostScript printers, color, portrait Std F77
TTDRIV 5 /XTERM XTERM Tektronix terminal emulator Std F77
WDDRIV 1 /WD X Window dump file, landscape
WDDRIV 2 /VWD X Window dump file, portrait
XWDRIV 1 /XWINDOW Workstations running X Window System C
XWDRIV 2 /XSERVE Persistent window on X Window System C
Edit the sys_cygwin configuration file to work with the
current version of cygwin. (TBD, update this file and pass on
to pgplot distribution for inclusion, for now see
PDL/cygwin/g77_gcc.conf)
$ vi sys_cygwin/g77_gcc.conf
# This diff command shows the lines that need changing
$ diff g77_gcc.conf*

$ ~/pgplot/makemake ~/pgplot cygwin
$ make
$ make clean
$ make cpg
$ PGPLOT_DIR="/usr/local/pgplot/"; export PGPLOT_DIR
Be sure to add PGPLOT_DIR to your environment and add it to
your PATH as well. Now we can build the PGPLOT module for
perl. Download from www.cpan.org if needed.
2. Now install the PGPLOT perl module. This is used by
PDL::Graphics::PGPLOT.
$ tar xzf PGPLOT-2.19.tar.gz
$ cd PGPLOT-2.19
# Be sure to set the environment!
$ export PGPLOT_DIR=/usr/local/pgplot
$ export PATH=$PGPLOT_DIR:$PATH
$ perl Makefile.PL
Hand edit the Makefile generated by Makefile.PL and correct
the link line (TBD: fix the Makefile.PL build process and
propagate cygwin fixes back to the module author. Sorry,
you'll have to edit this one).
$ vi Makefile
Edit the EXTRALIBS = ... and LDLOADLIBS = ... lines to change
"-lpgplot -lcpgplot" to "-lcpgplot -lpgplot -lpng -lz"
The first part of the modified lines look like this:
EXTRALIBS = -L/usr/X11R6/lib -L/usr/local/pgplot -lcpgplot -lpgplot -lpng -lz -lX11 ...
LDLOADLIBS = -L/usr/X11R6/lib -L/usr/local/pgplot -lcpgplot -lpgplot -lpng -lz -lX11 ...
Build it now:
$ make
# Lots of tests!
$ make test
$ make install
pgplot library is installed and working. PGPLOT module is
installed and working.
3. Build PDL configured to use PGPLOT (in perldl.conf file).
If your pgplot installation worked, it should be picked up
automatically.
NOTE: if problems see rebaseall below.
=================================================================
REBASEALL
=================================================================
There is a known issue on cygwin where DLLs have to have their
base addresses fixed so that runtime conflicts do not occur. The
problems occur for the external modules and their interfaces using
DLLs. Specifically, the DLLs in /usr/lib/perl5 and the DLLs in
the PLplot bin directory at least. The usual sign for this is
that some tests fail mysteriously. If you run the failing test
by hand (for example):
perl -Mblib t/plplot.t
You'll see no error but only 1 test run or even a message saying
that the test failed before generating any output. If so, you'll
need to run rebaseall:
0. Generate a list of additional DLLs to check:
find /usr/lib/perl5 /usr/local /pdl_build_dir/blib -iname '*.dll' > /bin/fixit.list
1. Exit all cygwin processes, windows, shells, X server,...
2. Start up a windows CMD shell window (Start->Run cmd)
3. cd to the cygwin /bin directory (cd c:\cygwin\bin by default)
4. Run ash in that directory (ash)
5. Run rebaseall (./rebaseall -T fixit.list)
Note that we created the fixit.list file in the c:\cygwin\bin
folder to begin with. If you put it elsewhere, you'll need
to use the appropriate pathnames.
After the rebaseall command has completed, you should be able to
start up X windows and rerun the failed tests (perl -Mblib t/testname.t)
or all tests (make test).
