Photos C++ Interface

Web page: http://photospp.web.cern.ch Repository: https://gitlab.cern.ch/photospp/photospp

Requirements

• Fortran compiler
• C++03 compiler (C++11 for HepMC3 interface)
• make or (cmake + any supported backend)
• Tauola++
• HepMC (optional)
• HepMC3 (optional)
• MC-TESTER (optional, for tests)
• Pythia8 (optional, for tests)
• Latex (optional, for documentation)
• Doxygen (optional, for documentation)

Build with cmake

cmake -S . -B BUILD <extra flags>
cmake --build BUILD
cmake --install BUILD

and then optionally

ctest --test-dir BUILD

to run the tests.

The extra flags might be either generic CMake flags, e.g. -DCMAKE_Fortran_COMPILER=ifort or the Photospp-specific flags

Photospp_ENABLE_HEPMC2      Enables building of with HepMC2 library, ON by default.
Photospp_ENABLE_HEPMC3      Enables building of with HepMC3 library, ON by default.
Photospp_ENABLE_EXAMPLES    Enables building of examples and testing them, ON by default.
Photospp_ENABLE_MC-TESTER   Enables building of examples with MC-TESTER and testing them, OFF by default.
Photospp_ENABLE_DOXYGEN     Enables building of Doxygen documentation, OFF by default.
Photospp_ENABLE_LATEX       Enables building of LaTeX documentation, OFF by default.

The location of the dependencies (HepMC, HepMC3, MC-TESTER, etc.) can be set with -DDEPENDNCYNAME_DIR=/my/location, e.g. -DMC-TESTER_DIR=/usr/local.

Build with autotools ( Deprecated, will not be updated )

Documentation is in documentation/latex_documentation, type "make" there

To compile the interface:

• Execute "./configure" (if the path to HepMC is not set with HEPMCLOCATION, use "./configure --with-hepmc=" or use "./configure --without-hepmc")
• Execute "make"

Alternatively cofiguration scripts based on autotools can be used. In this case 'cd platform', './use-LCG-config.sh' and
follow the instructions in the freshly created './INSTALL' readme file. The configure file in the directory 'examples' will be absent.
The instructions collected below should be then ignored.
Under MAC OS one may need to remove '-lfreetype' from
'examples/Makefile'

To run the examples, "cd examples". There "./configure" and "make" as well. For some of the examples to work, pythia8.1 and MC-Tester will be needed. The most basic example does not need them.
