Main Page -> Control & Readout Software Documentation and Howto's -> Building ROOT
In the pCT project we need to use a version of ROOT which is compiled with c++17 in order to build packages with ROOT dependencies with c++17 standard. .
ROOT implements a custom adaptor to std::string_view if not compiled with c++17 and this conflicts with the real one if a packages uses c++17 standard and ROOT libraries/includes.
# clone the repository
git clone http://github.com/root-project/root.git
# choose a build directory
mkdir build_root; cd build_root
# configure: choose install target, on the lab machine we need to disable asimage for some reason
# the important flag is the C++ standard
cmake3 -D CMAKE_INSTALL_PREFIX=/opt/root -D asimage=OFF -D CMAKE_CXX_STANDARD=17 ../
#build
make -j
# install (eventually using sudo)
make install
