HI All,
I am upgrading an existing app from OpenGL ES to Metal by changing my existing app following "MixingMetalAndOpenGLRenderingInAView".
It was going ok until I imported the files
AAPLOpenGLMetalInteropTexture.h
AAPLOpenGLMetalInteropTexture.m
Now when I compile the project I get the error:-
Undefined symbols for architecture arm64:
"_kCVPixelBufferOpenGLCompatibilityKey", referenced from:
-[AAPLOpenGLMetalInteropTexture initWithMetalDevice:openGLContext:metalPixelFormat:size:] in AAPLOpenGLMetalInteropTexture.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
the line of code is:-
NSDictionary* cvBufferProperties = @{
(__bridge NSString*)kCVPixelBufferOpenGLCompatibilityKey : @YES,
(__bridge NSString*)kCVPixelBufferMetalCompatibilityKey : @YES,
};
What am I doing wrong !!!!
