Your CPU is from 2009, it does not have a support for AVX2, only SSE. I will try to compile tonight a build of Igel specifically targeted for your ancient CPU

Hello Krzysztof, Question to the author of the engine: what happens to this chess engine. That the engine does not start.

That is exactly what happened. It was compiled and placed in the src folder. But when I run it, the UCI commands mostly do not function. ... and before you run the g++ command you also created a folder weights inside src and you downloaded the official network file ign-1-139b702b to it, right? so t...
