This document briefly describes the build process of the CAFAna framework contained in this package.

For documentation on the classes themselves, automatically generated Doxygen pages are maintained on our GitHub Pages site. (These are automatically updated when pull requests are merged to the master branch.)

Prerequisites

• A compiler that understands C++14 (tested with gcc)
• ROOT v6.00.00 or above

Build

The package should be built using CMake.

CMake builds are 'out-of-source' --- that is, they use a dedicated build directory that you can put anywhere. In this example, we'll use a build directory that is a subdirectory of the source root (that is, the directory containing this file).

By default, the generated libraries and test executables are installed back into the source tree at lib/ and bin/, respecively. If you'd like to put them somewhere else, pass -DCMAKE_INSTALL_PREFIX=/path/to/dir (where /path/to/dir is where you'd like them to be installed) in the cmake command below.

$ mkdir build
$ cd build
$ cmake ..
$ make install

How to build and and test your changes locally

• export QUALIFIER=e19:prof or e17:debug, etc
• jenkins/jenkins_build.sh (or paste parts of it into your terminal)
• set CAFANACORE_LIB and CAFANACORE_INC manually to point to what you just built
• rebuild your test release
• export CAFANA_DISABLE_VERSION_CHECK=1
• Profit!

How to build with jenkins

git push
git tag $NEW_TAG_NUMBER
git push --tags

• Navigate to https://buildmaster.fnal.gov/buildmaster/view/Nova/job/external/job/cafanacore_build/ and click "Build Now".
• Wait

How to deploy

wget https://buildmaster.fnal.gov/buildmaster/view/Nova/job/external/job/cafanacore_collect/lastSuccessfulBuild/artifact/*zip*/archive.zip
unzip archive.zip
mv archive/* .
rm archive.zip

ssh cvmfs${EXPERIMENT}@oasiscfs.fnal.gov
cvmfs_server transaction ${EXPERIMENT}.opensciencegrid.org
# fetch the files you extracted previously to the correct /cvmfs directory
cd /cvmfs/ ... /cafanacore/$NEW_TAG_NUMBER/include
ln -s . CAFAnaCore # can't be done earlier because neither jenkins or scp like symlinks
ln -s CAFAna/Core/ cafanacore
cd -
cvmfs_server publish ${EXPERIMENT}.opensciencegrid.org
