Installation
1) Setting up the system
External LIBRARIES needed:
- [GSL] (http://www.gnu.org/software/gsl/)
- [CFITSIO] (http://heasarc.gsfc.nasa.gov/fitsio/)
Please make sure you have the GNU autotools and the GNU GCC/G++ compiler properly installed.
HINT for MAC users: We recommend to install the GCC/G++ compiler for C/C++, the GNU autotools and the GSL/cfitsio libraries consistently with the same package manager. In particular, the installation process is fully tested within the HomeBrew environment ( https://brew.sh/ ). Within Homebrew, the following packages are needed:
- autoconf
- automake
- libtool
- cfitsio
- gsl
- gcc
2) Initialization
Before installing the code, you should launch this shell script to initialize the GNU autotools:
./start.sh
For MAC users:
./startMAC.sh
3) configure
Launch configure as in this example:
./configure --with-cfitsio=$CFITSIO_DIR --with-numcpu=2
The default installation path is in the same folder as the source code is (the program automatically creates the bin/ and lib/ subfolders).
It can be set via --prefix=<NEW_INSTALLATION_PATH>
Please try
./configure --help
if you need more information about installation options.
HINT for MAC users: We recommend to use the GCC/G++ compiler (e.g. as provided by HomeBrew) and explicitly instruct configure to use it.
Please check this example (g++-9 and gcc-9 are the compilers installed with the Homebrew package manager):
./configure --with-cfitsio=$CFITSIO_DIR CXX=g++-9 CC=gcc-9 --with-numcpu=2
4) make
With make you can finally create the DRAGON executable:
make
5) run
Run the example models in the examples/ directory:
./DRAGON examples/FILENAME.xml
