To set up, create a directory to work in:
mkdir rel21testing && cd $_
then clone me with the submodules fetched as well:
git clone --recursive <github url>
Next, create a build directory to build from CMake, set up the release, then try making:
mkdir build && cd $_ setupATLAS asetup AnalysisBase,2.6.1 cmake ../xAODAnaHelpersCMake make install DESTDIR=../install
After installing, my top-level looks like this:
$ ls total 28K drwxr-xr-x 5 kratsg 117 Apr 19 17:24 ./ drwxr--r-- 53 kratsg 4.0K Apr 19 17:17 ../ -rw-r--r-- 1 kratsg 13K Apr 19 10:56 .asetup.save drwxr-xr-x 6 kratsg 4.0K Apr 19 16:18 build/ drwxr-xr-x 3 kratsg 32 Apr 19 16:12 install/ drwxr-xr-x 4 kratsg 144 Apr 19 17:24 xAODAnaHelpersCMake/
where everything was installed to install. Now, to run code, I updated xAH_run.py to check if we are on 2.5/2.6 release series (the ones that use CMake) and requires an extra option: -L/--library-linking which needs a path to the installed shared library file you just made! So creating an example config.py for testing purposes, I run the code like this:
./install/InstallArea/x86_64-slc6-gcc49-opt/bin/xAH_run.py --config config.py \ --files input.root \ -L install/InstallArea/x86_64-slc6-gcc49-opt/lib/libxAODAnaHelpers.so \ direct
Notice that the path to the xAH_run.py needs to be specified. This isn't automatically in your $PATH yet, but I'm sure given time, a solution to make this happen in a cleaner way will come up. For now, just know that install/InstallArea/x86_64-slc6-gcc49-opt contains everything you've made, including bin/, lib/, data/, and docs/. The last thing is that I gave xAH_run.py the full path to where it can find the shared library, then inside xAH_run.py, it executes the following calls:
import ROOT
ROOT.gSystem.Load(args.ext_library)
xAH_logger.info("loading packages")
ROOT.gROOT.Macro("$ROOTCOREDIR/scripts/load_packages.C")
where the shared library that was made needs to be loaded in first before you can load in the RootCore macro here.
