从 python 到 pypy

Question

I am currently working on a project where the source files are all written in python. The files/modules are currently being run on a python interpreter(CPython). I want to use PyPy interpreter instead as i see it is much more efficient. Is there way how I can change the interpreter from the CMakeLists.txt file so the build process takes in PyPy interpreter instead of the python default interpreter? I have a project named P and it contains a CMakeLists.txt file.

Answer 1

When it needs python interpreter, CMakeLists.txt usually uses find_package(PythonInterp) , which searches python executable and sets PYTHON_EXECUTABLE to the path where it is located.

You may set this cache variable when call cmake :

cmake -DPYTHON_EXECUTABLE=<path-to-PyPy> ...

so it will not search executable but use one you provide.
