A suite of c++ libraries for radio astronomy data processing.
The casacore source code is maintained on github.
You can obtain it using:
$ git clone https://github.com/casacore/casacore
To compile casacore you need to meet the following requirements:
- cmake
- gfortran
- g++
- flex
- bison
- blas
- lapack
- cfitsio (3.181 or later)
- wcslib (4.20 or later)
- sofa (optional, only for testing casacore measures)
- fftw3 (optional)
- hdf5 (optional)
- numpy (optional)
- boost-python (optional)
- ncurses (optional)
On Debian / Ubuntu you can install these with:
$ sudo apt-get install build-essential cmake gfortran g++ libncurses5-dev \
libreadline-dev flex bison libblas-dev liblapacke-dev libcfitsio3-dev \
wcslib-dev
and the optional libraries:
$ sudo apt-get install libhdf5-serial-dev libfftw3-dev python-numpy \
libboost-python-dev
Various parts of casacore require measures data, which requires regular updating. You can obtain the WSRT measures archive from the ASTRON FTP server:
ftp://ftp.astron.nl/outgoing/Measures/
Extract this somewhere on a permanent location on your filesystem.
In the casacore source folder run:
mkdir build
cd build
cmake ..
make
make install
there are various flags available to cmake to enable and disable options:
$ cmake -DUSE_FFTW3=ON -DDATA_DIR=/usr/share/casacore/data -DUSE_OPENMP=ON \
-DUSE_HDF5=ON -DBUILD_PYTHON=ON -DUSE_THREADS=ON
The DATA_DIR should point to the location where you extracted the measures
data.
If you run into problems with boost libraries, try setting -DBoost_NO_BOOST_CMAKE=True. This will be necessary if you have the libraries from NRAO casa in your PATH or LD_LIBRARY_PATH.
If you run Ubuntu 14.04 you can use precompiled binary packages
