The linux port of CW-I that uses flatpak
Guide at: https://flathub.org/setup
For exaple: sudo chmod +x installer.out
For exaple: ./OpenCW.out
Thats it (no, seriously)
Error: ./OpenCW.out: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./OpenCW.out)
Fix: compile the source code yourself with g++. (This issue is because OpenCW was compiled with desktop ubuntu in mind so for example WSL might not work out of the box)
