EmotiBitOscilloscope not building on Mac M1 (Ventura 13.1)

[JaeminBBQ]

Describe the feature EmotiBitOscilloscope is not able to be built/compiled on Mac M1 (Ventura 13.1) following instructions in the readme. The feature would allow Mac M1 to compile the EmotiBit Oscilloscope.

Steps Taken

1. Download OpenFramework (Currently, 0.11.2 is the most recent release)
2. Follow instructions on ofxEmotiBit GitHub page.
3. Go to ofxEmotiBit and checkout to branch that supports Open Framework 0.11.2
4. On Xcode navber, Product -> Destination -> Destination Architectures -> Show Both
   • This will show both Rosetta and Apple Silicon destinations.

• Build on Apple Silicon

  1. ✅ EmotiBit DataParser Build Succeeded
  2. ✅ EmotiBit FirmwareInstaller Build Succeeded
  3. ❌ EmotBit Oscilliscope Build Failed

• Build on Rosetta

  1. ❌ EmotiBit DataParser Build Failed
  2. ❌ EmotiBit FirmwareInstaller Build Failed
  3. ❌ EmotBit Oscilliscope Build Failed

EmotiBit Oscilliscope Error when build failing Apple Silicon	GUI error message	Console Error message

EmotiBit Error when build failing Rosetta	DataParser	FirmwareInstaller	Oscilliscope

4. Build succeeds in DataParser, FirmwareInstaller, but fails for EmotiBitOscilloscope when using Apple Silicon
   • The build fails for all three when using Rosetta because of the same “apple-m1” error
   • The EmotiBitOscilloscope errors and log suggests that QTKit.tbd and liblsl are incompatible with ARM.

Steps taken that fixed the issue

1. Download Source Code of liblsl Release v1.14.0

2. Used CMake to create .dylib on M1 Mac

3. Replaced liblsl.1.14.0.dylib in ofxLSL/libs/labstreaminglayer/lib/osx with new dylib

4. Compiles successfuly ✅

Describe the solution you'd like Possible solutions

• ~If liblsl.1.14.0.dylib compiled on ARM works on intel Mac, replace current liblsl1.14.0.dylib with ARM.~
  • If this works with Intel Mac, only one file is changed and supports M1 and Intel Macs
• Separate OSX into ARM and Intel.
  • now requires maintaining another operating system

Both of these solutions require building a dylib not available from the liblsl GitHub page. This means that until they start adding ARM to their available assets, we will have to build the dylib ourself whenever we update the lsl dependency.
