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]  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.

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.
