This page collects the various specific README files (with installation and usage notes) associated to the scripts to install astronomical software on a laptop


Before launching IRAF, you may need to define a couple of environment variables. Put them inside your .bash_profile (or equivalent) file.

For sh and bash:
export iraf="/opt/iraf/iraf-2.16.1/"
export IRAFARCH="linux64"

If you are unable to change the font size in an XGterm, try the following fix:
cd /usr/share/X11/app-defaults/ ; sudo ln -sf /opt/iraf/iraf-2.16.1/vendor/x11iraf/app-defaults/XGterm

If, when launching IRAF from an XGterm, some error message is printed about undefined variables, open the XGterm with the -ls flag (which starts it as a login shell).

To install the i686 (32bit) packages under Ubuntu, try:
sudo apt install lib32gcc-8-dev lib32gcc-7-dev lib32ncurses5-dev lib32ncursesw5-dev libxmu6:i386 libxtst6:i386
