Cross-compiling programs?

Question

linux

Hello, I'm a linuxoid beginner, I recently read about cross-compiling on a linux host to other platforms (whether it's win32 or macos), could you tell me programs (or a list of programs) that you can manually compile on your own for different platforms (vlc I already collected)
Thanks in advance!

Answer 1

programs (or a list of programs) that you can manually build on your own for different platforms

All packages included in buildroot are cross-compiled.

Answer 2

All programs using SDL or Qt. For example:
Qt Creator
PPSSPP
Otter Browser (similar to Opera 12 browser)
Clementine
CoolReader3
qBittorrent
If resources allow, you can add Firefox and Thunderbird to the list.
