A suite of C++ libraries for radio astronomy data processing.
Casacore is now part of Debian and Ubuntu, use apt to search for the package you need:
$ apt-get update
$ apt-get search casacore
Use Homebrew with the ska-sa tap to install casacore:
$ brew tap ska-sa/tap
$ brew install casacoreWe now also publish docker images for each github branch on quay.io:
$ docker pull quay.io/casacore/casacore:master
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
- 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 libcfitsio-dev \
wcslib-dev libfftw3-dev
and the optional libraries:
$ sudo apt-get install libhdf5-serial-dev python-numpy \
libboost-python-dev libpython3.4-dev libpython2.7-dev
On CentOS7 you can install these with:
$ sudo yum install cmake cmake-gui gcc-gfortran gcc-c++ flex bison \
blas blas-devel lapack lapack-devel cfitsio cfitsio-devel \
wcslib wcslib-devel ncurses ncurses-devel readline readline-devel\
python-devel boost boost-devel fftw fftw-devel hdf5 hdf5-devel\
numpy boost-python 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 -DDATA_DIR=/usr/share/casacore/data -DUSE_OPENMP=ON \
-DUSE_HDF5=ON -DBUILD_PYTHON3=ON -DUSE_THREADS=ON
The DATA_DIR should point to the location where you extracted the measures
data. Special variables %CASAROOT% and %CASAHOME% can be used here, which
can be set at run time through the .casarc file.
Older versions of CMake may have problems detecting the correct python libraries and headers, in which case you may need to set them manually. For example:
-DPYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.4m.so
-DPYTHON3_INCLUDE_DIR=/usr/include/python3.4
To configure Python3 specific settings use:
PYTHON3_EXECUTABLE
PYTHON3_LIBRARY
PYTHON3_INCLUDE_DIR
If you run into problems with boost libraries, try setting -DBoost_NO_BOOST_CMAKE=True. This may be necessary if you have the libraries from NRAO casa in your PATH or LD_LIBRARY_PATH.
