In the Readme file the Greens library is described as:

This is the C++ Greens library. It provides a tool for calculation of the Coulomb wave functions and Coulomb Green’s functions both in nonrelativistic and relativistic framework.

I found nowhere in the code any license information at all, so I assume it is more or less public domain. The copyright is still by Peter Koval and Stephan Fritzsche. I hope someone finds this useful. This is the unmodified code of Koval and Fritzsche. I made some changes to the code so that it runs on modern Linux distributions and Mac OS X (including a CMakeLists.txt file) but I’m not sure if I’m allowed to distribute it, so I’ll contact the authors first.

Download “The Greens Library”

First we need to download and install the GTK Framework, which was described in this post.  Basically you need to:

1. Download the GTK_2.18.5-X11.pkg package from http://r.research.att.com/ and install it
2. Add to your .profile file in the home directory:

   export PATH=/Library/Frameworks/GTK+.framework/Resources/bin:$PATH
   

3. (Re)start Terminal.app and see if pkg-config cairo --libs works.

Then download Gnuplot 4.4.0, untar, configure and compile it:

1. Download Gnuplot 4.4.0 from Sourceforge.
2. tar xzf gnuplot-4.4.0.tar.gz
3. cd gnuplot-4.4.0
4. mkdir build && cd build
5. ../configure --with-readline=bsd --disable-wxwidgets
In the configure output you should find something like

     wxt terminal: no (requires C++, wxWidgets>2.6, cairo>0.9, pango>1.10)
     cairo-based pdf and png terminals: yes

6. make
7. sudo make install

Gnuplot will be installed in /usr/local/bin and should be ready to be used (if /usr/local/bin is in your path). pngcairo and pdfcairo are the new terminals you can use now. Gnuplot 4.4 has some major improvements so it may worth to install Gnuplot following these instructions.

Prerequisites

We need to make sure some packages are already installed before we try to compile gnuplot

• libwxgtk2.8-dev – for the wxt terminal
• libpango1.0-dev – for the cairo (pdf, png) and wxt terminals
• libreadline5-dev – readline support (editing command lines)
• libx11-dev and libxt-dev – X11 terminal
• texinfo (optional) – needed for the tutorial
• libgd2-xpm-dev (optional) – old png, jpeg and gif terminals based on libgd

This command (run in a terminal) will install all prerequisites if not already installed:

sudo apt-get install libwxgtk2.8-dev libpango1.0-dev libreadline5-dev libx11-dev libxt-dev texinfo libgd2-xpm-dev

Then we download and compile gnuplot (run each command/line in a terminal)

• wget http://sourceforge.net/projects/gnuplot/files/gnuplot/4.4.0/gnuplot-4.4.0.tar.gz/download
• tar xzf gnuplot-4.4.0.tar.gz
• mkdir build && cd build
• ../gnuplot-4.4.0/configure --with-readline=gnu

check if you find the lines in the output at the bottom:

X Window System terminal: yes
jpeg terminal: yes
gif terminal: yes (with animated gif)
png terminal: yes
    (jpeg, gif and png terminals can use TTF fonts)
wxt terminal: yes
cairo-based pdf and png terminals: yes
Readline library: GNU readline library with  -lncurses

• make

(if you have problems here with some latex errors than disable the latex tutorial during the configure stage with “--without-tutorial”, if you get a “103: makeinfo: not found” error message than install the texinfo package)

• sudo make install

Then you have gnuplot installed with nice readline support (command line like in bash), a nice new wxWidgets terminal and a pdf terminal based on cairo.

There are some possibilities to install Gnuplot on Mac OS X, none of them is “official”, since the Gnuplot project doesn’t provide binaries for Mac OS X. It’s actually quite easy to configure and compile Gnuplot (i.e. ./configure; make; make install), but some terminals are not built due to missing dependencies and this makes Gnuplot less powerful.

There is some information on the web about running Gnuplot on Mac OS X already (http://lee-phillips.org/info/Macintosh/gnuplot.html , http://maba.wordpress.com/2006/08/02/scientific-plotting-on-mac-os-x-using-gnuplot-and-plot/ ) and there is also http://www.finkproject.org/ and http://www.macports.org/ but there is IMO an easier way (though it still needs some work): there is a Gnuplot installer provided by Octave! Here are the instructions:

• Download Octave for Mac OS X from the Octaveforge homepage (latest version at time of writing was 3.2.2).
• Open the downloaded dmg file and browse to the Extras folder
• Open gnuplot-4.2.5-i386.dmg and copy Gnuplot.app to your Applications folder (or anywhere else).
• Alternatively you could directly download the gnuplot-4.2.5-i386.dmg from here.

That’s about it. Or at least it should be. Usually you just open Gnuplot.app and start plotting. But unfortunately the default aquaterm terminal doesn’t work for me always (on one Mac it did, on another it didn’t – maybe Aquaterm shouldn’t be installed before). So we need to hack Gnuplot.app so that X11 (which is also more powerful) becomes the default terminal.

• Right click on Gnuplot.app and choose “Show Package Contents”.
• Browse to Contents/Resources and edit “script” with your favorite text editor
• Replace both lines do script (“exec ‘${ROOT}/bin/gnuplot’”) with do script (“GNUTERM=x11 exec ‘${ROOT}/bin/gnuplot’”) . X11 will then be the default terminal.

You might also want to have gnuplot available in your usual terminal session. This is also no problem. Just run the following command in your terminal

ln -s /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot /Users/username/bin/gnuplot

where username is your user name. /Users/username/bin must be added to the path, so that Gnuplot works form everywhere, e.g. you could add the following to the /Users/username/.profile file

# add bin directory of home directory
export PATH=$HOME/bin:$PATH

If you run gnuplot from the Terminal.app again the Aquaterm terminal is the default. This can be changed by adding

# use x11 as the default Gnuplot terminal
export GNUTERM=x11

to your .profile file.

Binaries of the GSL 1.11 were already provided in an earlier post including instructions on how the package was assembled. Here, the binaries for GSL 1.12 are provided.

This new package also contains a modified gsl-config bash script – this script will now return the correct paths to the library regardless where you install the package (but can only be used inside MSYS). It’s also possible to use the pkg-config utility, but here you must set the PKG_CONFIG_PATH environment variable to the gsl-1.12/lib-shared/pkgconfig or gsl-1.12/lib-static/pkgconfig directory. The package also contains the import libraries for Visual C++. The dlls are stripped, so there is no debugging information in there.

“The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite”.

GSL is quite Unix centric but one might want to use the library at least with MinGW on Windows. I didn’t find any MinGW binaries of GSL apart from the one provided by the Ascend package or the binaries from GNUWin32 (which is only at version 1.8), but I don’t like graphical installers for libraries and I needed the static library. Therefore I compiled my own library with MSYS (I updated MSYS according to this link) and provide here the tarred binary package, which can also be used with the MinGW compiler without MSYS and with Visual C (import libraries for the shared library are provided).

There are no makefiles for the MinGW compiler but it is possible to compile the GSL in the MSYS development environment. I wrote a little bash script which downloads the GSL source package (with the help of curl), untars the package, compiles the source and assembles the binaries and necessary files for development in a tar.gz package using 7zip. Curl and 7zip need to be in the path or in the same directory as the script. The script will create a gsl_mingw directory where the source package is downloaded to and all compilation steps will take place. The tar.gz package will be created in gsl_mingw/package and copied to the directory where the script was run. Below you can download the binary package of GSL 1.11 for the MinGW 3.4.5 compiler toolset (to be used in MSYS and in native Windows CLI) and the script I wrote to compile GSL in MSYS yourself if you want. I also added the import libraries for Visual C (only for the shared GSL) according GNUWin32 descriptions.

Download: GSL 1.11 Binary for MinGW 3.4.5 (with Visual C import libraries)

The script will create a directory “gsl_mingw” in the same directory where the script is run. Before the scripts starts downloading the GSL package, it shows some informations and waits for user input.

After you have all the images in a folder, install ffmpeg, in Ubuntu/Debian Linux e.g.

sudo apt-get install ffmpeg

In order to make a movie (mp4 quicktime) out of the images you need to issue the following command

ffmpeg -qscale 5 -r 20 -b 9600 -i img%04d.png movie.mp4

The options are

• -qscale 5 … define fixed video quantizer scale (VBR) where 1 is the best and 31 the worst. Since mpeg/jpeg has problems to compress line graphics it’s a good idea to set this variable close to 1. You get a big movie file, but otherwise the movie doesn’t look, well, that good.
• -r … framerate
• -b … video bitrate
• -i input files, %04d says that we have four numbers in the filename where the number is filled with zeros left of it.
• movie.mp4 is the filename, the extension says that it is a quicktime movie. You can also create a Macromedia Flash movie by using the .flv extension.

Links:

• Homepage, where I found most of these instructions: http://electron.mit.edu/~gsteele/ffmpeg/
• ffmpeg Homepage: http://ffmpeg.mplayerhq.hu/
• ffmpeg Documentation: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html

There is an updated Howto for Ubuntu Gutsy Gibbon available.

Though there is gnuplot available in the Ubuntu/Debian repositories, there are reasons to compile gnuplot – first and most important gnu readline support! I don’t know why Debian maintainers don’t compile the GNU readline support into GNUplot – it’s some license issues – but it’s like that and this makes gnuplot practically unusable. Second having the pdf and wxWidgets terminal is not that bad at all

So here are the instructions:

First we compile and install wxWidgets

• Download wxWidgets GTK 2.8.3
• Untar it somewhere: tar xzf wxGTK-2.8.3.tar.gz
• cd cd wxGTK-2.8.3/
• mkdir buildgtk
• cd buildgtk
• ../configure
• make
• sudo paco -lp wxGTK-2.8.3 make install (or just make install if you don’t use paco)
• sudo ldconfig (you may need to add /usr/local/lib to the file /etc/ld.so.conf before)

Than we are going to install the PDFlib lite

• Download PDFlib Lite
• tar xzf PDFlib-Lite-7.0.1.tar.gz
• cd PDFlib-Lite-7.0.1
• ./configure
• make
• sudo paco -lD make install
• sudo ldconfig

Than we compile gnuplot

• Download gnuplot 4.2
• tar xzf gnuplot-4.2.0.tar.gz
• cd gnuplot-4.2.0
• ./configure –with-readline=gnu (check if we have the lines “pdf terminal: yes” and “wxt terminal: yes (EXPERIMENTAL)”, if you miss the jpeg, png and gif terminal install the libgd2-xpm-dev package; also check if you find “Readline library: GNU readline library with -lncurses”, if it says only minimal readline support than install the libreadline5-dev package; you need also the libx11-dev and libxt-dev package for the X11 terminal – libxt-dev package is normally not installed by default (at the debian page about gnuplot one can find the packages necessary to build gnuplot))
• make (if you have problems here with some latex errors than disable the latex tutorial during the configure stage with “–without-tutorial”, if you get a “103: makeinfo: not found” error message than install the texinfo package)
• sudo paco -lD make install

Than you have gnuplot installed with nice readline support (command line like in bash), a nice new wxWidgets terminal and a pdf terminal.

Scanning the internet I found this forum entry in German where it was proposed to add the command “\protect” before “\subref{fig:1}, which actually did the trick for me. I didn’t have this problem though with MikTeX.
