Update setting PYTHON_BIN_PATH message --define -> --repo_env The error message about not finding the python binary PYTHON_BIN_PATH that is --define'ed was confusing: --define does not work, but --repo_env does. Maybe this worked in older bazel versions ? Signed-off-by: Henner Zeller <h.zeller@acm.org>
Provided rules:
pybind_extension: Builds a python extension, automatically adding the required build flags and pybind11 dependencies. It defines a *.so target which can be included as a data dependency of a py_* target.pybind_library: Builds a C++ library, automatically adding the required build flags and pybind11 dependencies. This library can then be used as a dependency of a pybind_extension. The arguments match a cc_library.pybind_library_test: Builds a C++ test for a pybind_library. The arguments match a cc_test.To test a pybind_extension, the most common approach is to write the test in python and use the standard py_test build rule.
Provided targets:
@pybind11//:pybind11_embed: Automatically adds required build flags to embed Python. Add as a dependency to your cc_binary.
@pybind11//:pybind11_embed currently supports Python 3 MacOS/Ubuntu/Debian environments:
If pybind11_embed doesn't work with your embedded Python project, add @pybind11 as a dependency to your cc_binary and follow the instructions for manually retrieving the build flags.
In your WORKSPACE file:
http_archive( name = "pybind11_bazel", strip_prefix = "pybind11_bazel-<stable-commit>", urls = ["https://github.com/pybind/pybind11_bazel/archive/<stable-commit>.zip"], ) # We still require the pybind library. http_archive( name = "pybind11", build_file = "@pybind11_bazel//:pybind11.BUILD", strip_prefix = "pybind11-<stable-version>", urls = ["https://github.com/pybind/pybind11/archive/v<stable-version>.tar.gz"], ) load("@pybind11_bazel//:python_configure.bzl", "python_configure") python_configure(name = "local_config_python")
Then, in your BUILD file:
load("@pybind11_bazel//:build_defs.bzl", "pybind_extension")
To configure pybind11_bazel for hermetic Python, python_configure can take the target providing the Python runtime as an argument:
python_configure( name = "local_config_python", python_interpreter_target = "@python_interpreter//:python_bin", )
