Provided rules:
pybind_extension
: Builds a python extension, automatically adding the required build flags and pybind11 dependencies. It defines a target which can be included as adata
dependency of apy_*
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 apybind_extension
. The arguments match acc_library
.pybind_library_test
: Builds a C++ test for apybind_library
. The arguments match acc_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.
To embed Python, add @rules_python//python/cc:current_py_cc_libs
as a
dependency to your cc_binary
.
In your WORKSPACE
file:
http_archive(
name = "pybind11_bazel",
strip_prefix = "pybind11_bazel-<version>",
urls = ["https://github.com/pybind/pybind11_bazel/archive/v<version>.zip"],
)
# We still require the pybind library.
http_archive(
name = "pybind11",
build_file = "@pybind11_bazel//:pybind11-BUILD.bazel",
strip_prefix = "pybind11-<version>",
urls = ["https://github.com/pybind/pybind11/archive/v<version>.zip"],
)
Then, in your BUILD
file:
load("@pybind11_bazel//:build_defs.bzl", "pybind_extension")
In your MODULE.bazel
file:
bazel_dep(name = "pybind11_bazel", version = "<version>")
Usage in your BUILD
file is as described previously.
