GDL setup with Astronomy library (open-source IDL replacement)

sudo apt-get install gnudatalanguage edit your .bashrc, adding the line: export GDL_STARTUP=~/.gdl/gdl-startup.pro Now to say setup the Astronomy Library for GDL, download it from http://idlastro.gsfc.nasa.gov/ftp/astron.dir.tar.gz and extract to say ~/IDLtoolbox/astrolib finally let’s edit the gdl-startup.pro nano ~/.gdl/gdl-startup.pro and paste in: !PATH=!PATH+’:'+Expand_Path(‘+~/IDLtoolbox/astrolib/’) which keeps the current paths and adds all the Astronomy library subdirectories. to check […]

Compiling GDL (gnudatalanguage) 0.9.4 on Ubuntu

I wanted the bugfixes and improvements of GDL 0.9.4 over the 0.9.2 that comes with Ubuntu 12.04 and the 0.9.3 that comes with Ubuntu 13.10. Get the sources, extract to a directory, and install these packages (sudo apt-get install) libbz2-dev libplplot-dev libfontconfig1-dev libplplot-dev libncurses5-dev libreadline-dev libgsl0-dev libwxgtk2.8-dev libmagick++-dev libnetcdf-dev libhdf4-alt-dev libgraphicsmagick++1-devel libhdf5-serial-dev libfftw3-dev python-dev libeigen3-dev […]

Converting IDL code to MATLAB or SciLab code automatically

Note: from Python, you can try PyIDL: The “idl2matlab” SourceForge project publishes source code that you can compile under Windows or Linux to attempt to automatically convert IDL code to MATLAB code. http://sourceforge.net/projects/idl2matlab/ In May 2013 IDL2MATLAB version 1.6 was updated to use current version of GCC. Prerequisites: sudo apt-get install libbison-dev flex ./configure now […]
