Installation
CASA is continually being tested under Linux - Red Hat 7 & Red Hat 6, Mac OS X - macOS 10.13 (High Sierra) & macOS 10.12 (Sierra), but may also work on other distributions such as Ubuntu Linux.
To install CASA on Ubuntu Linux versions 14.04, 16.04 and 18.04 follow these steps:
1. Downloading the current release of the CASA code for your specific operating system (we will download release version for Red Hat 7)
2. Move to the directory where you downloaded the file ...tar.gz (casa-release-5.4.0-68.el7.tar.gz, in Downloads for our case) and then unpack it:
- $cd ~/Downloads
- $tar -xzvf casa-release-5.4.0-68.el7.tar.gz
The binaries are pre-compiled, we just need to unpack them.
3. Make a symbolic link (also symlink or soft link) to it in a path location so that you can start CASA by typing "casa" from anywhere in the Terminal:
- sudo ln -s $HOME/Downloads/casa-release-5.4.0-68.el7/bin/casa /usr/local/bin/casa
You can however add the directory where the binary is located to your path instead of making symlink:
- export PATH=$PATH://casa-release-5.4.0-68.el7/bin
When you type casa from the Terminal, you should see something like this:
