Installing the development version¶
The current development version of the code can be downloaded as source tarballs, Mac OS X binaries, or directly from the Git repository.
The current ctools development release is ctools-1.6.0.dev1.
Source tarballs¶
Download the source tarballs from the following links
and follow the instructions on Installing from source code.
Binary packages¶
Download the installer image from the following link
and follow the instructions on Installing as binary package.
Git repository¶
To clone the gammalib and ctools source codes, type
$ git clone https://cta-gitlab.irap.omp.eu/gammalib/gammalib.git
$ git clone https://cta-gitlab.irap.omp.eu/ctools/ctools.git
This will create directories named gammalib and ctools under the current working directory that will contain the gammalib and ctools source code. In case that the cloning does not work you may try adding
$ export GIT_SSL_NO_VERIFY=true
or
$ git config --global http.sslverify "false"
before retrieving the code.
Before you will be able to compile the code you need to generate the
configuration file using the autogen.sh script.
Also make sure that you’re actually on the devel branch of the git
repository. GammaLib and ctools can be compiled and configured using
the following command sequence (the code will be installed into the
/usr/local/gamma directory):
$ cd gammalib
$ git checkout devel
$ ./autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install
$ export GAMMALIB=/usr/local/gamma
$ source $GAMMALIB/bin/gammalib-init.sh
$ cd ../ctools
$ git checkout devel
$ ./autogen.sh
$ ./configure
$ make
$ make check
$ sudo make install
$ export CTOOLS=/usr/local/gamma
$ source $CTOOLS/bin/ctools-init.sh
Please read the Installing from source code section if you need more information on how to install ctools.
Note
You need swig on your system to build the Python wrappers when you get the code from Git. Python wrappers are not stored in the Git repository but are built using swig from interface files located in the pyext folder. However, you do not need swig when fetching a release as the Python wrappers are bundled with the release tarballs.
