Basically is there any way to render a pixel using C/C++ without using any external library. All mingw or gcc headers may be used.
You cannot render images to the screen without external libraries, unless you do hardcore system programming (see for instance this answer fore more information). But you can easily render images that you can save as PNG/JPEG/TIF files, which is what I believe this library is doing.

What is your WoW (Way of Working) when you are trying to reduce the use of libraries in C++ that are not needed or not even used anymore in your projects?
For now what I am doing is trying to comment out libraries in the Android.bp file (bp - blue print) and then build.
If it builds successful, I remove the library entry in the Android.bp file (if not I active the library again) and go to the next library and so on. This way seems a bit odd and I wonder how you would address this task?

I intend to use OpenCV for a project in which I've already built the server in Go. However, OpenCV doesn't have a Go API, so what's the best solution? Call a c++ program with .exec, use swig, find another library to do computer vision?
Thanks.
Edit: I want to maximize performance, and I'm ok with C++.
SWIG is certainly a viable option.
You can also search for a Go binding to OpenCV. For example: https://github.com/lazywei/go-opencv

I notice that in many game folders, I cannot find the resource files (sounds, game scripts, textures...). Is that because I don't see it or the programmers have hidden them somewhere?
I'm learning to make my first game in SDL2.
They will often be compressed into .cab or other kinds of archival formats to decrease required space and provide tamper protection.

How can I make my own GUI library e.g. SFML?
This question is for the purpose of understanding how GUI libraries work, not to actually make my own library.
I asked what I needed to do so. Can I open my editor and write some C++ code, importing some libraries and that's it. Or it's more complicated?
A library is "just" a bunch of classes and functions, so you write it like a normal program. The only thing that is different is when you compile it: you have to create a static/dynamic library file.

I'm trying to write text-based gui. Is there a way to access terminal per pixel using pure C++? I read a one method, but it was SDL based ;[
Not sure what you imply by "Pure C++", but ncurses is the go-to library for CLI applications (and there is a port for Windows called pdcurses )
