Apple M2 + Sonoma: Save-file example crashes. #7

Closed g40 closed 11 months ago

g40 commented 11 months ago

Hello.

save-file example crashes running under lldb after compiling with clang. lldb trace shown below.

Any thoughts?

Hey, is this a problem with silicon.h? If so it might be better to put the issue in that repository instead. I don't think Eima minds however.

I'll look into the issue later.

ColleagueRiley commented 11 months ago

The crash seems to be caused by the ARM processor. However, even when running the program using x86 it outputs 

2023-11-27 17:02:24.327 save-file[1430:17137] -[NSWindow OnButtonClick]: unrecognized selector sent to instance 0x7f940ad0bb50

Meaning the same issue is happening, just on ARM it results in a crash. This should be relatively easy to fix.

@ColleagueRiley Hello,

I'd agree re ARM64. Quite possibly related to the last problem.

BTW I am commenting here because issues are unavailable on your fork.

ColleagueRiley commented 11 months ago

Oh, that's strange. Github acts a little strange when it comes to forks.

But the issue should be solved now. It was more so an issue on my part and how I misinterpreted some code for the original example.

g40 commented 11 months ago

Well, one thing at a time.

It might be a good idea to add "-g -o0" to the clang command line in the meantime so debug info is maintained.

In respect of the latter:

Is that output after the update? Is it still not working for you?

g40 commented 11 months ago

I do believe so.

ColleagueRiley commented 11 months ago

I do believe so.

Well, the first issue was solved. But this actually helps a lot because I was just doing some testing and realized the function randomly stopped working running NSInit() (and returning to main on it's own)

So this actually shows that NSInit has some sort of error. That's weird that the x84 version doesn't even care to tell you that there was an issue and just leaves you to guess.

ColleagueRiley commented 11 months ago

Okay, so it turned out there were two issues (with the last issue that you hadn't gotten two yet) 1) a missing replacement function 2) I messed something up when fixing the casting issue

Point being, both those issues are fixed now and the example should work as intended.

g40 commented 11 months ago

Excellent. The save-file example= works. I'll let you know if any other problems emerge. Thanks.
