Buildspec TutorialΒΆ

Please proceed to Buildspec Overview to get an overview of how to write buildspecs. This section can be done on your workstation.

Tutorials SetupΒΆ

Note

The tutorial setup is required if you want to run buildspecs using the the compiler and spack schema.

To get started for this tutorial, you will need docker on your machine to pull the container. At NERSC, you can use shifter to access the container, you will need to start an interactive shell.

docker pull ghcr.io/buildtesters/buildtest_spack:latest
docker run -it ghcr.io/buildtesters/buildtest_spack:latest /bin/bash --login
shifter -E --image=registry.services.nersc.gov/siddiq90/buildtest_spack:latest -- /bin/bash --login

We need to install buildtest and setup environment for this tutorial. We recommend you clone buildtest in your HOME directory. This can be done as follows:

cd ~
git clone https://github.com/buildtesters/buildtest.git
cd buildtest
source scripts/spack_container/setup.sh

This container provides a software stack built with spack, you should see buildtest, spack and module command in your path. The configuration file used for this container is set via BUILDTEST_CONFIGFILE.

spack@ef50085c8a81:~/buildtest$ which spack
/home/spack/spack/bin/spack

spack@ef50085c8a81:~/buildtest$ which buildtest
/home/spack/buildtest/bin/buildtest

spack@ef50085c8a81:~/buildtest$ module --version
