If you see an error like this when running on Windows 10:

AL lib: (EE) ALCwasapiCapture_resetProxy: Failed to initialize audio client: 0x80070005
Failed to open the audio capture device with the name: OpenAL Soft on Microphone Array (Realtek High Definition Audio(SST))

0x80070005 means "Permission denied".

Graphics

"Created OpenGL context does not fully meet the settings that were requested"

If you see this warning when running Empty Epsilon:

Warning: The created OpenGL context does not fully meet the settings that were requested
Requested: version = 2.0 ; depth bits = 24 ; stencil bits = 8 ; AA level = 8 ; core = false ; debug = false ; sRGB = false
Created: version = 3.1 ; depth bits = 24 ; stencil bits = 8 ; AA level = 4 ; core = false ; debug = false ; sRGB = false

Your system might not support all of the graphics features that Empty Epsilon can use. In the above example, the device does not suport 8x full-screen anti-aliasing (FSAA). Avoid setting FSAA to 8x on this device.

This is just a warning; however, if there are issues with graphics quality, stability, or performance, the device might not have a sufficient GPU for roles involving 3D rendering.

OS compatibility

"Symbol not found: chkstk_darwin" on macOS

If this error appears when attempting to run on older versions of macOS:

dyld: lazy symbol binding failed: Symbol not found: chkstk_darwin
  Referenced from: /Users/Shared/EmptyEpsilon/EmptyEpsilon.app/Contents/MacOS/./EmptyEpsilon
  Expected in: /usr/lib/libSystem.B.dylib

The build you're running was likely made on a newer version of macOS and is incompatible with yours. You can try to either build Empty Epsilon yourself or upgrade macOS to a newer version.
