Modified Nov 3, 2021 to be more explicit. To build the rolloffino roof driver, development libraries and 3rdparty driver build files are needed. If you do not already have the current development files installed, see the directions in the web page below. https://indilib.org/forum/general/210-howto-building-latest-libindi-ekos.html. Section 1 Contains the normal INDI install directions. Section 2 Install the packages to get the development libraries. Perform down to and including the git clone to fetch the INDI source tree. Do not do the cmake build unless you want to run you own build of INDI. Section 3 With your default directory set to ~/Projects or whatever you are using for a base. If you already have the 3rdparty drivers installed that match the version you wish to build against no need to recreate them. If their version does not match then delete the existing 3rdparty tree. Install the packages to get the libraries and then perform the git clone. No need to go beyond the clone. In addition to the libraries already installed, install libindi-dev. There should now be two subdirectories of ~/Projects indi and the indi-3rdparty tree of drivers. These directories should be from the same version of INDI and match the version you are running. $ cd ~/Projects/indi-3rdparty $ git clone https://github.com/wotalota/indi-rolloffino.git This obtains the rolloffino sources and puts them in ~/Projects/indi-3rdparty/indi-rolloffino Make a directory below ths and set it as your default in which to do the build. $ mkdir indi-rolloffino/build $ cd indi-rolloffino/build $ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ../ $ make -j4 $ sudo make install This will build and install the indi_rolloffino roof driver if it completes without error the following files can be found. The driver executable: /usr/bin/indi_rolloffino Identifies it to Ekos: /usr/share/indi/indi_rolloffino.xml The driver will then be available for selection in Ekos using the profile editor in the Dome section.
