The correct include for pybind11, though you can turn it off as shown above if If loaded correctly, this should even pick up This, you will need to import from a local file in setup.py and ensure theĬlosely related, if you include pybind11 as a subproject, you can run the So you can use it with git submodules and a specific git version. Set include_pybind11=False to skip including the pybind11 package headers, You can also copy setup_helpers.py directly to your project it wasĭesigned to be usable standalone, like the old example setup.py. This is obviously more of a hack than the PEP 518 method, but it supports It doesn’t matter that the Extension class is not the enhanced subclass for theįirst pass run and the second pass will have the setup_requires Try : from tup_helpers import Pybind11Extension except ImportError : from setuptools import Extension as Pybind11Extension Your pyproject.toml file will likely look something like this:

When this file exists, Pip will make a new If you use PEP 518’s pyproject.toml file, you can ensure that pybind11 is available during PEP 518 requirements (Pip 10+ required) # Another way to force a rebuild is purge your cache Version number that includes the number of commits since your last tag and a One way to avoid this is to use, which will generate a Keep in mind that Pip will not even attempt to rebuild if it thinks it hasĪlready built a copy of your code, which it deduces from the version number. Simple solution, this even works even when not compiling in editable mode, but would be the way to use it with GCC, for example. It to needs_recompile, or you can use instead. If you have a more complex build, you can implement a smarter function and pass Use it like this:įrom tup_helpers import ParallelCompile, naive_recompile ParallelCompile ( "NPY_NUM_BUILD_JOBS", needs_recompile = naive_recompile ). Since pybind11 does not require NumPy when building, a light-weight replacementįor NumPy’s parallel compilation distutils tool is included.

Intree_extension will automatically detect if you are using a src-style Module will be generated and made available upon installation.
