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
