README.build

To build GENFIT cmake is needed in version 2.6 or higher.

To create the library, create a build directory and change into it. E.g.
  mkdir build; cd build
 
Now create the Makefiles by invoking:
  cmake ..

And build:
  make
 
The libraries are created in the subdirectory lib/ of the build directory.

To install the libraries and copy all header files into the directories lib/ and
include/ in the root directory of the project, invoke
  make install

 
To build the doxygen:
  make doc
  
To build the examples/tests (also see README in test/):
  make tests

The ROOT dicitionary requires to know the include paths of the libraries during runtime. To run GenFit, one has to
define the ROOT_INCLUDE_PATH environment variable. The reason is, that we use the from Eigen recommended include pattern
e.g. Eigen/Dense and not eigen3/Eigen/Dense. Because of this, the ROOT dictionaries can not find the headers. Run
  export ROOT_INCLUDE_PATH=/path/to/eigen3
to make the Eigen headers visible.


To build GFRave and the vertexing examples, you need an installation of Rave (https://rave.hepforge.org/), and the environment variable RAVEPATH set.
  export RAVEPATH=<yourRaveDirectory>
