Casacore + CASA image analysis

This is a custom version of casacore which includes the CASA image analysis component. It is required as a dependency for the backend component of the CARTA image viewer.

Installing measures data

Various parts of casacore depend on measures data. On Ubuntu we recommend installing the casacore-data package, either the default Ubuntu version or the package provided by the KERN suite.

Note: Ubuntu casacore-data packages now install the data directory in /var/lib (although some files may be symbolic links to /usr/share or vice versa), and Ubuntu casacore packages expect to find it in that location. The location used by our source build is ${CMAKE_INSTALL_PREFIX}/share/casacore/data (default /usr/local/share/casacore/data), but you can specify a custom location by adding a flag to cmake, for example -DDATA_DIR=/usr/share/casacore/data.

Ubuntu packages

We provide packages for Ubuntu 20.04 (Focal Fossa) and 18.04 (Bionic Beaver) in a PPA on Launchpad. These packages install the headers and shared library files to a custom location in /opt/carta-casacore, so that they do not interfere with any existing casacore packages which may be installed from the default Ubuntu repositories or from KERN.

The casacore-data package is recommended by our packages and will be installed automatically by default. Use the --no-install-recommends flag with apt to suppress this behaviour.

# Add the PPA to your system
sudo add-apt-repository ppa:cartavis-team/carta
sudo apt-get update

# Install CASA dependencies for building the CARTA backend from source
sudo apt-get install carta-casacore-dev

# If you install the binary CARTA backend package, all binary dependencies will be installed automatically.

Install carta-casacore from source

The build dependencies are the same as for casacore.

Ensure that you specify the correct data directory in a cmake parameter if it is not in the default /usr/share location, for example -DDATA_DIR=/var/lib/casacore/data to specify the latest Ubuntu location.

The CARTA backend source code looks for casacore headers and library files in the location used by the Ubuntu package, so we recommend that you specify the same install location using CMAKE_INSTALL_PREFIX if you are building carta-casacore from source.
