Advanced installation instructions

In case the dependencies ROOT and fmt are not installable with a package manager or you encounter some compatibility issues, the following tips may help you compile them manually.

Building ROOT from source:

One reason you might need to compile ROOT from source is that SciRooPlot depends on cxx17 and ROOT has some compatibility issues when software using a different cxx standard is linked to it (see here ). This problem will result in errors such as:

error: conflicting declaration of template ‘template<class _CharT, class _Traits> using basic_string_view = std::experimental::__ROOT::basic_string_view<_CharT, _Traits>’
using basic_string_view = ::std::experimental::basic_string_view<_CharT,_Traits>;

To solve this you can compile ROOT with the cxx17 standard:

git clone https://github.com/root-project/root.git
cd root && mkdir mybuild && cd mybuild
cmake -DCMAKE_CXX_STANDARD=17 .. && make

For SciRooPlot to find this ROOT installation add the location to the CMAKE_PREFIX_PATH:

export CMAKE_PREFIX_PATH=/path/to/root/mybuild:$CMAKE_PREFIX_PATH

Alternatively, you can pass this information directly to SciRooPlot via the compiler flag: -DROOTSYS=/path/to/root/mybuild

Building fmt from source:

One reason you might need to compile fmt from source is that cmake’s find_package(fmt) picks up a different fmt that comes with the GNU Utilities on common Linux distributions. To avoid this you can compile your own fmt version:

git clone https://github.com/fmtlib/fmt.git
cd fmt && mkdir build && cd build
cmake -DBUILD_SHARED_LIBS=TRUE .. && make

For SciRooPlot to find this fmt installation add the location to the CMAKE_PREFIX_PATH:

export CMAKE_PREFIX_PATH=/path/to/fmt/build:$CMAKE_PREFIX_PATH

Alternatively, you can pass this information directly to SciRooPlot via the compiler flag: -DFMT_ROOT=/path/to/fmt/build

Autocomplete:

In case the autocompletion does not work, on MacOS you need to run autoload -U compaudit compinit prior to sourcing the .plotrc.
