AddInstanceForFactory & HALC_ShellDriverPlugIn errors when using SDL2 with Xcode?

Question

I am trying to make a simple game using SDL2 and C++ on Xcode 11.2.1; however, my progress has been stopped by an error.

All it takes to encounter these errors is simply initializing SDL. Just calling this function will cause the program to crash:

SDL_Init(SDL_INIT_EVERYTHING);

Giving these errors:

Westerino[16795:847932] Metal API Validation Enabled
Westerino[16795:848288] flock failed to lock maps file: errno = 35
Westerino[16795:848288] flock failed to lock maps file: errno = 35
Westerino[16795:847932] [plugin] AddInstanceForFactory: No factory registered for id <CFUUID 0x102157f00> F8BB1C28-BAE8-11D6-9C31-00039315CD46

Westerino[16795:847932]  HALC_ShellDriverPlugIn::Open: Can't get a pointer to the Open routine

I have tried clearing the cache, cleaning the build, deleting the preferences, reinstalling the framework, etc. but nothing has helped yet.

It seems like these issues may have started when I updated Xcode, but I cannot confirm that.

Would this be better off on the game development stack overflow? – Islean

Googling around it looks like the F8BB1C28-BAE8-11D6-9C31-00039315CD46 UUID & the HALC_ShellDriverPlugIn string indicates it might be audio-related; does init-ing only SDL_INIT_VIDEO change anything? Which version of macOS are you using? – Florina

@Florina I am using Mac OS Catalina 10.15.1. Using only SDL_INIT_VIDEO still causes the first three lines of errors and crashing. – Islean

Are you using AudioKit, by any chance? I am seeing the same [plugin] and HALC_ messages in my AudioKit-based project. – Fellows

Answer 1

The same issue here. I am also using Catalina 10.15.1 and XCode 11.2.1. Although, I managed to build and debug using CodeLLDB in VSCode. Also, turning off "C++: on throw" breakpoints helps to run the program without any pauses.

Answer 2

The message "Metal API Validation Enabled" is harmless and can be turned off easily. Go to Product/Scheme/Edit Scheme, click on the Diagnostics tab, and turn off the "Metal API Validation" option.

Boo

The Metal API Validation stuff is in the Options tab, not the Diagnostics tab, at least in my XCode 11.5. – Radome
