How to compile a program so that it works everywhere (g++)?

Question

C++ / C#

Hello! The question is: how should a program be compiled so that it can run on any machine (Intel and AMD) with optimizations enabled? Link to the program (my chess engine): https://github.com/sovaz1997/Zevra

Answer 1

1. separate the optimized functionality into a separate library.
2. compile it with various optimizations
3. in your code - decide on the plug-in version
4. connect it.
But it's probably easier to use source distribution and "in-place" building.

Answer 2

1) The start module determines the type of processor used
2) Based on the results of the check, a dynamic connection of modules (.so) is called for the detected architecture.

Answer 3

Read about scheduling.
