For example, Python 3.11 has two folders as shown below, one for Arm64 and another for x86_64: /usr/lib/python3.11/config-3.11-aarch64-linux-gnu/ /usr/lib/python3.11/config-3.11-x86_64-linux-gnu/ This commit updates the Python configuration path based on the compiler's machine type, guiding the compiler to find the correct path for Python libraries. It also renames the generated .so file name to match the machine name.
