cvmfs

Scripts to build the CVMFS repository for IceCube/WIPAC.

Current Build

Inside the correct OS environment (possibly inside a container), run the following python scripts (using python3).

Build the base software:

spack/build_v2.py py3-v4.3.0 --dest /cvmfs/icecube.opensciencegrid.org --src ../icecube.opensciencegrid.org

Build icetray metaprojects

spack/build_v2.py py3-v4.3.0-metaproject --dest /cvmfs/icecube.opensciencegrid.org --src ../icecube.opensciencegrid.org

Done!

Mirrors

You can use a filesystem mirror for the base software build, by adding the argument

--mirror /path/to/mirror

This allows caching of package downloads between builds, especially helpful when debugging.

Metaproject Checkout

For the icetray metaproject build, there is a checkout-only mode for populating the universal src directory once, before building various OS versions. Use the option --checkout and it will do a source code checkout and skip the build.

Parallel Builds

By default, Spack will use a single core to build. To use multiple cores, set the environment variable CPUS=10 (using 10 cores in this example).

Generic Build Instructions

Spack Build

Build a single variant:

spack/build_v2.py py3-v4.3.0 --dest /cvmfs/icecube.opensciencegrid.org --src ../icecube.opensciencegrid.org

Note that there are two build scripts. v2 applies for py3-v4.3.0 and later.

Editing a Spack Build

There is a base file, then extensions for -compiler, -pip, and -metaproject.

A regular build will look for -compiler first, and if found will build all projects with that compiler. Then it will build all the packages specified in the base file. Finally it will run pip install -r on the -pip file.

A metaproject build with the -metaproject file specified will build icetray metaprojects into the base build (must be performed after the base build is successful).

System Dependencies

gcc, make, autoconf (standard build system)
git
python

Old Build

py2 builds

To build all variants at once:

cd builders;./build.py --dest /cvmfs/icecube.opensciencegrid.org --src ../icecube.opensciencegrid.org

Or you can select a variant to build:

cd builders;./build.py --dest /cvmfs/icecube.opensciencegrid.org --src ../icecube.opensciencegrid.org --variant py2_v2_base
