Installing the DST Tools
The DST maker and HpsEvent API require the following packages before they can be built:
The default, shared Linux environment at SLAC can not be used as the version of gcc is too old.
On SLAC, a more recent environment can be setup and checked as follows.
ssh rhel6-64 scl enable devtoolset-2 gcc --version
You should see the following gcc version now.
(GCC) 4.8.2 20140120 (Red Hat 4.8.2-15) Copyright (C) 2013 Free Software
This version of the compiler should support the C++11 standard.
An alternate compiler also needs to be setup to override the default one.
export PATH=/apps/gcc/4.8.2/bin/:$PATH gcc --version
You should see the following GCC version.
gcc (GCC) 4.8.2
It is likely your system already has a recent enough version of CMake installed on it.
You can check for this from the shell.
which cmake cmake
It will print something like this if CMake is installed.
$ which cmake /usr/bin/cmake $ cmake cmake version 2.8.12.2 [...]
If CMake is not found, then follow the Installing CMake guide to build it.
cd workdir svn co svn://svn.freehep.org/lcio/trunk lcio-trunk cd lcio-trunk mkdir build cd build cmake -DINSTALL_DOC=OFF -DINSTALL_JAR=OFF .. make install cd .. export LCIO=$PWD
Follow the instructions at the ROOT website to install it. Then you will want to source the setup script which will set the ROOTSYS variable.
. bin/thisroot.sh
cd workdir svn checkout http://svnsrv.desy.de/public/GeneralBrokenLines/tags/V01-16-02 GeneralBrokenLines cd GeneralBrokenLines/cpp mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=../.. .. make install cd ../.. export GBL_DIR=$PWD
The project is stored in a public github repository. The code can be "cloned" i.e. copied to a users local machine by issuing the following commands from a terminal.
cd /path/to/workdir git clone https://github.com/omar-moreno/hps-dst.git
A github account is not required to clone the source code.
Before the project is built, the following environment variables need to be set.
ROOTSYS=/path/to/root GBL_DIR=/path/to/gbl/cpp LCIO=/path/to/lcio
Then the project should be built as follows.
cd hps-dst/ mkdir build; cd build cmake ../ make
This will create the binaries in the build/bin directory along with the shared library HpsEvent.so in the build/lib directory, which contains the ROOT dictionary and HPS Event API.
The API documentation can be generated as follows:
make doc
This will generate both LaTeX and html documentation in the directory hps-dst/doc.
