Hall C ROOT/C++ Analyzer (hcana) Documentation

hcana is an under-development tool to analyze data from the HMS, SHMS and SOS spectrometers in Hall C at JLab. It is being developed to replace the historical Hall C analyzer, ENGINE, which was written in Fortran. hcana will be the package used to analyze Hall C date in the 12 GeV era. hcana is being written in C++, using the CERN ROOT framework. hcana is an extension to the Hall A analyzer, PODD.

NOTE: In the process of retrieving the hcana source code, a copy of the Hall A PODD package will be downloaded. The version of PODD included has been slightly modified for use with hcana. For an official version of PODD, see the ROOT/C++ Analyzer for Hall A page.

Downloading

Instructions for downloading hcana can be found in the Hall C Wiki.

Compiling

hcana may be compiled with either make or scons. Switching between these two build systems make require some cleanup of dependency files, binary files and other autogenerated files.

Before compiling, type source setup.sh or source setup.csh depending on whether your shell is bash or csh.

Compiling with scons

``` scons ```

Additional SCons features

To do the equivalent of "make clean", do scons -c To compile with debug capabilities, do scons debug=1 To compile the standalone codes the are part of podd, do scons standalone=1 To run cppcheck (if installed) on the Hall C src diretory, do scons cppcheck=1

Compiling with CMake (experimental)

Do the usual CMake setup

``` mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=$HOME/local/hcana .. make -jN install ```

Here $HOME/local/hcana is an example installation destination; modify as appropriate. You will need to add the bin and lib[64] sub-directories under the installation prefix to your environment:

``` export PATH=$HOME/local/hcana/bin:$PATH export LD_LIBRARY_PATH=$HOME/local/hcana/lib64:$LD_LIBRARY_PATH ```

On macOS, the library directory is usually simply lib instead of lib64.

CMake does not yet support the SCons features "standalone" and "cppcheck".

The default CMake build type is "RelWithDebInfo", i.e. debug symbols are included in the binaries, but the code is optimized, which may cause the debugger to act in a confusing way on occasion. To build a non-optimized debug version, run CMake as follows: ``` mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$HOME/local/hcana-dbg .. make -jN install ```

Compiling with make (deprecated)

``` make [-jN] ```

Running

Basic instructions on how to run hcana are in the Hall C Wiki.
