Yes, I am aware. I did not argue that is isn’t for testing. I said you didn’t need to compile it for Mac or Windows, because it’s not expected of you to have a CS degree to install it.
You probably just need to use chmod to let your system know it’s allowed to execute it.
WTF is chmod? Execute what? How can you not see that this is a problem?
It is a problem. The fact Windows will just execute anything is an issue. That’s right. On Linux you need to tell your system to execute a file. That’s what chmod is for. (I think you may be able to do this with a right-click. I’m not sure. You just need to tell your system that a file is an executable and it’s allowed to do so.)
Well now you’re just blatantly lying. Windows doesn’t execute anything without you asking it to. The difference is that it works when you do.
