README
# Casacore
A suite of C++ libraries for radio astronomy data processing.
# Installation
## Debian / Ubuntu
Casacore is now part of Debian and Ubuntu, use apt to search for the package you need:
```bash
$ apt-get update
$ apt-get search casacore
```
## MacOS
Use Homebrew with the `ska-sa` tap to install casacore:
```bash
$ brew tap ska-sa/tap
$ brew install casacore
```
## Docker
We now also publish docker images for each github branch on [quay.io](https://quay.io/repository/casacore/casacore):
```
$ docker pull quay.io/casacore/casacore:master
```
## Building from source
### Getting the source code
The casacore source code is maintained on github.
You can obtain it using:
```
$ git clone https://github.com/casacore/casacore
```
### Requirements
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:
```bash
$ 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
```
## Obtaining measures data
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.
## Compilation
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`.
