GNU/Linux NullReferenceException on startup #1633

Closed rdrpenguin04 closed 5 years ago

rdrpenguin04 commented 5 years ago

Followed Building->GNU+Linux instructions, using unix_emerg_patch branch to fix #1632. When I run the emulator (BizHawk_master/output/EmuHawkMono.sh), it crashes:

(Mono really wanted me to C/P the whole thing there)

The terminal is blank. When I close the window, the terminal reports that the program was killed. Is there a known fix for this? I tried to Ctrl-F in #1430, but no luck except for once the emulator has actually started.

Let me know if there's anything else I can post that can help, or if I should move this to #1430 or whatnot.

I've had another look at it and it seems my fix only works when I run msbuild from Rider (and is only necessary in this case), regardless of how I run the executable. Knowing this, I'll just use the command line instead.

YoshiRulz commented 5 years ago

You should be able to use master now. As for being helpful, keeping Linux-specific issues in #1430 is a good idea but IRC would be better.

rdrpenguin04 commented 5 years ago

Thank you for letting me know! BTW, what IRC do you mean? Do you mean the TASVideos Discord or something specific to this?
