Release notes


November 5, 2019

  • initial public release



  • ROOT 6 (with RooFit and Minuit2 support)
  • CMake 2.8


cd /some/directory
git clone
cd FooFit
mkdir build
cd build
cmake ..
make install
export LD_LIBRARY_PATH="/some/directory/FooFit/build/lib:$LD_LIBRARY_PATH"
export ROOT_INCLUDE_PATH="/some/directory/FooFit/build/include:$ROOT_INCLUDE_PATH"

It is recommended to set the LD_LIBRARY_PATH and ROOT_INCLUDE_PATH variables in your shell configuration file.

Quick start

If LD_LIBRARY_PATH and ROOT_INCLUDE_PATH are set, root should be able to find the library automatically. If not, there are several ways to load the library:

ROOT command line interface:

root [0] gSystem->Load("");

Interpreted macros:

void FooFitMacro()

Compiled macros:

root [0] .include /some/directory/FooFit/build/include
root [1] .x FooFitMacro.C++
