Documentation lives at https://www.clearskyinstitute.com/xephem/ where Elwood Downey — XEphem’s original author and its maintainer since the 1990s — offers a manual, data files, and user contributed scripts.
-
Elwood Downey has generously released XEphem under the MIT License! An “XEphem” organization has been created on GitHub to host XEphem’s source code.
-
The XEphem community hopes to modernize the code to make it easier to compile, package, and run on modern systems. In the meantime, XEphem compiles most readily on older Linux platforms like Ubuntu 14.04.
-
If you want to get started immediately, a Docker image that successfully compiles and runs XEphem atop Ubuntu 14.04 is available in the “docker” branch on GitHub. It’s documented in this README file.
-
The repository also includes a
.titodirectory andxephem.specfile for building an XEphem RPM package. -
Otherwise, if you want to tackle XEphem development on another platform, start with the INSTALL file in the
mainbranch of the repository. -
