Ensure that build tools with module-level commands in spack use the version built as part of their build graph if one exists. This is now also required for mesa, scons, cmake and ctest, out of graph versions of these tools in path will not be found unless added as an external. This bug appeared because a new version of rocprim needs cmake 3.16, while I have 3.14 in my path I had added an external for cmake 3.20 to the dag, but 3.14 was still used to configure rocprim causing it to fail. As far as I can tell, all the build tools added in build_environment.py had this problem, despite the fact that they should have been resolving these tools by name with a path search and find the one in the dag that way. I'm still investigating why the path searching and Executable logic didn't do it, but this makes three of the build systems much more explicit, and leaves only gmake and ninja as dependencies from out in the system while ensuring the version in the dag is used if there is one. The additional sqlite version is to perturb the hash of python to work around a relocation bug which will be fixed in a subsequent PR. |

Spack
Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.
Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.
See the Feature Overview for examples and highlights.
To install spack and your first package, make sure you have Python. Then:
$ git clone -c feature.manyFiles=true https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install zlib
Documentation
Full documentation is available, or
run spack help
or spack help --all
.
For a cheat sheet on Spack syntax, run spack help --spec
.
Tutorial
We maintain a hands-on tutorial. It covers basic to advanced usage, packaging, developer features, and large HPC deployments. You can do all of the exercises on your own laptop using a Docker container.
Feel free to use these materials to teach users at your organization about Spack.
Community
Spack is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.
Resources:
- Slack workspace: spackpm.slack.com. To get an invitation, visit slack.spack.io.
- Mailing list: groups.google.com/d/forum/spack
- Twitter: @spackpm. Be sure to
@mention
us!
Contributing
Contributing to Spack is relatively easy. Just send us a
pull request.
When you send your request, make develop
the destination branch on the
Spack repository.
Your PR must pass Spack's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with our CI process. To run these tests locally, and for helpful tips on git, see our Contribution Guide.
Spack's develop
branch has the latest contributions. Pull requests
should target develop
, and users who want the latest package versions,
features, etc. can use develop
.
Releases
For multi-user site deployments or other use cases that need very stable software installations, we recommend using Spack's stable releases.
Each Spack release series also has a corresponding branch, e.g.
releases/v0.14
has 0.14.x
versions of Spack, and releases/v0.13
has
0.13.x
versions. We backport important bug fixes to these branches but
we do not advance the package versions or make other changes that would
change the way Spack concretizes dependencies within a release branch.
So, you can base your Spack deployment on a release branch and git pull
to get fixes, without the package churn that comes with develop
.
The latest release is always available with the releases/latest
tag.
See the docs on releases for more details.
