          Writing C software without the standard library

There are many tutorials on the web that explain how to build a
simple hello world in C without the libc on AMD64, but most of them
stop there.

I will provide a more complete explanation that will allow you to
build yourself a little framework to write more complex programs.

Goal

Find a replacement for Llama (R.I.P. 😢)

Conclusion

🦙 Keep using Llama! 🦙

• Llama still works and no other application seems to match Llama in terms of ease of use and cell-tower location (Llama's killer feature)
• Cell-tower location UX seems to be unmatched by the alternatives (training new locations, ignoring towers, seeing location events)

This guide applies only to KSP 1.8 and latter. It covers modifying a KSP installation to allow :

• In IDE debugging of KSP plugins by using breakpoints, inspecting runtime variables, doing step-by-step execution, etc. Both Visual Studio (including VS for Mac) and JetBrains Rider support debugging Unity games, and by extension KSP plugins.
• Using the Unity editor profiling tools, which include great tools to measure and analyze CPU/GPU usage and memory allocations.

This guide is extensively tested for a Windows / Visual Studio scenario. However, it is theoretically possible to make all that work under MacOS or Linux, either with the Rider IDE or Visual Studio for Mac. This guide has limited details about those scenarios. I encourage you to leave a comment if you have additional information / experience.
