Error once used in another project

[Mezo-hx]

I'm making a hack another game other than csgo, and I realized you used a shell file rather than a processManager, so I decided to use it... But I keep getting this error

Hey! Does this script work for you for other games (e.g. CS:GO)? Secondly, does the game's executable include debug info? You can check this with file or objdump --sys.

objdump --sys

It does seem to work with csgo I haven't checked if the games executable includes a debug info yet, but one thing I forgot to point out is that it's running on Wine... So would that perhaps cause any issues?

[deboogerxyz]

The executable was probably compiled using MSVC and I don't think it's possible to attach GDB to it. I don't think you can even inject .so files to it. I once tried making a cross-platform TF2 cheat. I compiled the Windows version with mingw and tested it with Proton. The only way to inject it was to use a .dll injector written for Windows and run it through Wine (it's a bit more complicated than that with Proton).

Alright, thanks for the information!
