CMake is a widely used cross-platform build system that facilitates the build process for C and C++ projects. In this tutorial, we will explore how to install a Python package that relies on CMake for its build process. This is a common scenario for packages that include C or C++ extensions.
Before starting, make sure you have the following installed on your system:
Let's start by creating a simple Python package that includes a C extension. Create a directory for your project and navigate to it:
Inside this directory, create the following files:
Now that we have our simple Python package with a C extension and a CMake build script, let's build and install it.
Create a build directory inside your project folder and navigate to it:
Run CMake to generate the build files:
Build the project using your preferred build tool (e.g., make on Linux):
Install the package using the following command:
This will install your Python package along with the C extension.
Create a test script (e.g., test_package.py) to verify that the installed package works correctly:
Run the test script:
If everything is set up correctly, you should see the output:
Congratulations! You have successfully installed a Python package with CMake, including a C extension.
