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.
<syntaxhighlight lang="bash">
- 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
cmake -D CMAKE_INSTALL_PREFIX=/opt/root -D asimage=OFF -D CMAKE_CXX_STANDARD=17 ../root
- build
make -j
- install (eventually using sudo)
make install </syntaxhighlight>
