XRootD cannot be built in-source! Please run cmake <src-dir> outside the source directory and be sure to remove CMakeCache.txt or CMakeFiles if they exist in the source directory.

  • install in /cern/root_master (source dir) and build in /cern/root_master_build (out of source dir)
  • it is not supported to build ROOT on the source directory
  • location independent installation method
  • by default CMAKE_INSTALL_PREFIX=/usr/local
  • don't try CMAKE_INSTALL_PREFIX=. (install files and up-to-date files => make install and make loop)
  • Before trying to build ROOT, see the “Build Prerequisites” web page. In any case, when you are building a new ROOT version, make always sure that nothing in your environment variables (i.e. “ROOTSYS”, “PATH”, “LD_LIBRARY_PATH”) points to another existing version of ROOT (and that’s another good reason why there should be no ROOT related files in “standard” system locations, like “/usr/[bin|lib]” or “/usr/local/[bin|lib]”).

  • to start from a clean configuration it is recommended to delete the file root_master_build/CMakeCache.txt
  • You can inspect the list of options and their descriptions by running cmake -LH $PWD in the build directory
