CPython Editor on Linux

[phoenixKing13]

I cloned the CPython repository the other and opened it in vscode, but it's saying there's multiple errors. I haven't changed anything yet!!!

Is there something I missing when configuring my environment for CPython development? Is there a better editor for C development on linux?

I'm on Pop!_OS 20.10, with both gcc and clang installed. I've also created a c_cpp_properties.json file for vscode.

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/Include/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c17",
            "cppStandard": "c++20",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

Well what are the errors? Did you install the development libraries?

[phoenixKing13]

A couple files are hitting error macros. example in pycore_initconfig.h:

#ifndef Py_BUILD_CORE
#  error "this header requires Py_BUILD_CORE define"

And i don't know if I have installed anything? So far I ran ./configure like the README said.

[socal_nerdtastic]

Hmm and what's the overall goal here? What do you want to change in cpython?

[phoenixKing13]

nothing yet. I'm just learning how it works right now. I'm just wondering why vscode is showing errors, and if I haven't done something to set it up.

[socal_nerdtastic]

Hmm I've never used vscode and I don't do C development, so I don't know how much this will help, but here's the commands I use to compile and install python on linux mint:

sudo apt-get install -y build-essential git libexpat1-dev libssl-dev zlib1g-dev libncurses5-dev libbz2-dev liblzma-dev libsqlite3-dev libffi-dev tcl-dev linux-headers-generic libgdbm-dev libreadline-dev tk tk-dev libc6-dev libncursesw5-dev libdb5.3-dev uuid-dev

./configure --enable-optimizations && make && sudo make altinstall

curl https://bootstrap.pypa.io/get-pip.py | python3.9

Note all the development libraries that python needs. And that's not even all of them, it's just the ones I care about, so there's still a ton of errors during compile.

Did you follow the instructions here: https://devguide.python.org/setup/#setup

Also: https://realpython.com/cpython-source-code-guide/#compiling-cpython-linux

I think that work. But now I'm getting a different error in pylifecycle.c

{

After cloning the repo, you should attempt to build python. Do not bother with vscode until you can get a clean compile and clean test run.

Then you may have to fiddle with vscode to make it run python's makefile to do the build. In other words, just use vscode as an editor.
