QUESTION
I am fairly new to the Cython world, but I know C and Python well. I am trying to use Cython to compile a Python code into C, but I need to write my own main() function in C.
I have only found one example online of a code that is compiled from a C program that calls a function written in Python/Cython, but they don't tell you how to compile it. See that example here: https://docs.cython.org/en/latest/src/tutorial/embedding.html
To be clear, I would prefer being able to compile a Python code and call it from C rather than running the Python interpreter in C.
To compile this myself, I am using Rocky Linux running the default Python version (3.6.8).
I am using the two codes seen referenced in the above example with no modifications. To compile these codes, I started with the UNIX Makefile from the github link that is mentioned in the example and added a line of code to compile the "embedded_main.c" code:

Answered 2022-Jan-24 at 00:07You need to check if the node version installed in your machine is compatible with the node-sass version installed in the project.
In your terminal do node -v
to check your node version and look at the node-sass version of the cloned project in the package.json
file. Look at the following answer for more information on what version of node-sass is compatible with what version of node.

I'm trying to create a simple C extension to Python and get it to run on OS X. I'm running Python 3.6. My method is apparently not getting exported from the module. Stripped down, my code looks like this:

...ANSWER
Answered 2021-Sep-15 at 21:47The ctypes
module is meant for accessing dynamically loaded libraries in regular C. You are creating a python extension. Since python functions in C are declared as static, myfunc
is not exposed in your .so
file. You need to compile the extension in distutils or setuptools then import the module in your python code. If you would like to use ctypes like your example, you need to rewrite your code in C similar to below.

QUESTION
I have a large program written in C++ that I wish to make usable via Python. I've written a python extension to expose an interface through which python code can call the C++ functions. The issue I'm having with this is that installing seems to be nontrivial.
All documentation I can find seems to indicate that I should create a setup.py
which creates a distutils.core.Extension
. In every example I've found, the Extension object being created is given a list of source files, which it compiles. If my code was one or two files, this would be fine. Unfortunately, it's dozens of files, and I use a number of relatively complicated visual studio build settings. As a result, building by listing .c files seems to be challenging to say the least.
I've currently configured my Python extension to build as a .dll and link against python39.lib. I tried changing the extension to .pyd and including the file in a manifest.in. After I created a setup.py and ran it, it created a .egg file that I verified did include the .pyd I created. However, after installing it, when I imported the module into python, the module was completely empty (and I verified that the PyInit_[module] function was not called). Python dll Extension Import says that I can import the dll if I change the extension to .pyd and place the file in the Dlls directory of python's installation. I've encountered two problems with this.
The first is that it seems to me that it's not very distributable like this. I'd like to package this into a python wheel, and I'm not sure how a wheel could do this. The second is even more problematic - it doesn't exactly work. It calls the initialization function of my extension, and I've verified in WinDbg that it's returning a python module. However, this is what I always get from the console.
...ANSWER
Answered 2021-Mar-26 at 15:32Let me try and divide your post into two separate questions:
- How to package a C++ library with a non-trivial compilation process using setuptools
- Is it possible to distribute a python package with a precompiled library
It is possible. I was quite surprised to see that setuptools
offers many ways to override the compilation process, see the documentation here. For example, you can use the keyword argument extra_compile_args
to pass extra arguments to the compiler.
In addition, as setup.py
is a python file, you could relatively easily write some code to automatically collect all files needed for compilation. I'd done this myself in a project (github), and it worked quite well for me.
Here's some code from the setup.py
:

ANSWER
Answered 2021-Mar-17 at 02:32Note: This might not be a complete answer, but it might be a starting place for one.
Possibly in answer to your first question, and based on the comments from earlier, this project looks to me like it might be a Flask web application. Flask is a Python microframework that can be used to build simple or complex web applications. I'm guessing this based on the following observations:
- The
passenger_wsgi.py
file - The observation of the files ending in
.py
made by brombeer in the comments - The item at the bottom of your application structure list called
myapp_flask
As far as the passenger_wsgi.py
file, Passenger is a web application server used to run web applications written in things like Python, Ruby, or Node.js.
As far as brombeer's observation about the file extensions, files that end in .py
are typically Python files.
As far as that myapp_flask
item, if there are contents inside this file or folder, I wonder if it might contain the main web application code. Would it be possible to check that file or folder to see if it contains application code? Warning: It might contain sensitive data (e.g., passwords, secrets, or keys), so I don't know if it should be posted in your original post above.
So, I guess I touched on your second main question in that earlier response: you might be able to find the main web application code in the myapp_flask
item. If nothing is there, however, you might be able to determine where the main application code is by looking at the contents of your passenger_wsgi.py
.
In this example passenger_wsgi.py
file in the Passenger documentation, it shows how an example (Django, in that case) application might be referred to in this type of file. If you open your passenger_wsgi.py
in a text editor, it might a show a reference to the main application code on a line that contains the term application =
(or something similar), like in the earlier example. Maybe this could help you know what the name of the application might be.
Then, you could possibly use grep
to search for the application name in your file structure, if grep
is available on your system. Maybe using a search command like: grep -r 'application-name' *
. That might give you more clues as to where the main application code is located.
As far as the additional note about your ImportError: cannot import name _remove_dead_weakref
error, I don't know if it's similar to this other question from the past. I would recommend caution, however, before changing up your Python 2 related setup based on answers in that other question thread, unless you are alright with whatever might happen along the way. I haven't tried out the answers myself from that thread.

Install pylib
You can use pylib like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
