Building Physsim and the example processors

In order to build Physsim the easiest way to satisfy all dependencies is to either use a Key4hep or a recent iLCSoft release. The instructions are very similar for both, the major difference is in the invokation of the cmake command, where -C ${ILCSOFT}/ILCSoft.cmake has to be replaced by -DCMAKE_CXX_STANDARD=17 when using a Key4hep release.

• Setup a recent iLCSoft release, e.g.

source /cvmfs/ilc.desy.de/sw/x86_64_gcc103_centos7/v02-03-01/init_ilcsoft.sh

• Clone the Physsim repository

git clone https://github.com/iLCSoft/Physsim
cd Physsim

• Build and install Physsim

mkdir build
cd build
cmake -C ${ILCSOFT}/ILCSoft.cmake -DCMAKE_INSTALL_PREFIX=../install ..
make install  # use -j<N> to build with N proceses in parallel

• Setup the environment to use the Physsim that you have just built (assuming you are still in the build directory). Note that the lib64 folder might be called lib depending on the OS you are using, please change accordingly

cd ../install
export CMAKE_PREFIX_PATH=$(pwd):$CMAKE_PREFIX_PATH
export LD_LIBRARY_PATH=$(pwd)/lib64:$LD_LIBRARY_PATH
cd ..

• Build the example processors (assuming that you start from the Physsim top-level directory)

cd example_stdhep
mkdir build
cd build
cmake -C ${ILCSOFT}/ILCSoft.cmake -DCMAKE_INSTALL_PREFIX=../install ..
make install  # use -j<N> to build with N processes in parallel

• Afterwards, the usual steps of adding the processors to MARLIN_DLL are necessary in order for Marlin to be able to find them
