rules_openblas

Bazel build rules for OpenBLAS.

About

Uses rules_foreign_cc to do a CMake configuration (default options), build, and install of OpenBLAS from source. This allows the user to include @openblas in the deps argument in project BUILD files. See the examples folder for a simple example.

For usage see the instructions with the latest release.

Tested

• Windows 10
• Ubuntu 20.04.5 LTS
• MacOS 12.6.3

Troubleshooting

If the CMake configuration or build fails I recommend to check the CMake.log under $(GENDIR)/openblas_foreign_cc for any errors. Use bazel info --show_make_env if you are unsure of GENDIR.

If you suspect that the errors can be resolved with cmake configuration options:

• Clone this repository.
• Adjust the cmake rule in BUILD with custom settings for your system.
• Replace the http_archive function with a local_repository function pointing to the cloned repo in WORKSPACE.

Future

• I'd like to expose options for the user to have more control over the cmake rule. For now, you are limited to default options.
• Expand portability to a broader range of systems and environments
