-------
On Windows, use the `CMake GUI`_ to create a Visual Studio project. Note that
only the 2015 release and newer versions are supported since pybind11 relies on
various C++11 language features that break older versions of Visual Studio.
After running CMake, open the created :file:`pybind11.sln` file and perform a
release build, which will will produce a file named
:file:`Release\\example.pyd`. Copy this file to the :file:`example` directory
and run :file:`example\\run_test.py` using the targeted Python version.
On Windows, only **Visual Studio 2015** and newer are supported since pybind11 relies
on various C++11 language features that break older versions of Visual Studio.
.. _`CMake GUI`: https://cmake.org/runningcmake
To compile and run the tests:
.. code-block:: batch
mkdir build
cd build
cmake ..
cmake --build . --config Release --target pytest
This will create a Visual Studio project, compile and run the target, all from the
command line.
.. Note::
When all tests fail, make sure that
1. The Python binary and the testcases are compiled for the same processor
type and bitness (i.e. either **i386** or **x86_64**)
2. The Python binary used to run :file:`example\\run_test.py` matches the
Python version specified in the CMake GUI. This is controlled via
the ``PYTHON_EXECUTABLE`` ``PYTHON_INCLUDE_DIR``, and
``PYTHON_LIBRARY`` variables.
If all tests fail, make sure that the Python binary and the testcases are compiled
for the same processor type and bitness (i.e. either **i386** or **x86_64**). You
can specify **x86_64** as the target architecture for the generated Visual Studio
project using ``cmake -A x64 ..``.
