SIGILL crash upon running the game for the first time

[karimhamdanali]

Hi there,

Thanks for making this mod available. Much appreciated!

I tried installing it on macOS by following the instructions on the wiki. Although the installation was successful, the app crashed upon running it from the command line (via ./launch-game.sh). I was wondering if you may have any pointers to resolve this runtime error? I installed the mod on macOS 10.15.4 and my machine runs mono 6.8.0.105 (installed via homebrew). The full crash report is below (redacted some personal paths).

Thanks!

Got a SIGILL while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

It seems that the build crashes with mono. However, after I downloaded and installed Visual Studio for Mac from Microsoft's website, then did a make all, the game opened properly without crashing.

Perhaps Visual Studio installed more runtime libraries than mono did? I'm not sure to be honest.

The crash does look like it is an issue with mono. It might be because it was installed via homebrew. (It is recommended to install from https://www.mono-project.com/download/stable/#download-mac.)

Anyway, glad to hear that you managed to resolve this crash/issue.
