Hello, regarding cross-compilation, the main approach we recommend is by setting environment variables or writing a Makefile. These two methods are actually quite similar. We also have detailed tutorials on our wiki that you can refer to. https://wiki.luckfox.com/Luckfox-Pico-Pro-Max/Cross-Compile ...

Team luckfox,

I want to understand how this thing works, specially cross compilation. As I was more familiar with Rasp OS which had its own compilation.
Due to size we need to compile in virutal OS Ubuntu 22.04.5 LTS. Download luckfox SDK and then use it to compile apps.

I usually used direct gcc ...
