CLion: Getting `avr-g++: error: unrecognized command line option '-mmacosx-version-min=10.14'`

Hello!

I keep getting this error from CMake in CLion:

"/Users/matt/Library/Application Support/JetBrains/Toolbox/apps/CLion/ch-0/192.6817.32/CLion.app/Contents/bin/cmake/mac/bin/cmake" -DCMAKE_BUILD_TYPE=uno -G "CodeBlocks - Unix Makefiles" /Users/matt/Downloads/spooky-candy-surprise

Problems were encountered while collecting compiler information:
	avr-g++: error: unrecognized command line option '-mmacosx-version-min=10.14'

[Finished]

Here is the GitHub repo to the project files.

Does anyone know why this is happening or how I can fix this?

Thanks :slight_smile:

Have a look through this thread… it looks to be something to do with a newer version of XCode (and the SDK it installs?)

Hmm… I see. I’d rather not downgrade my Xcode version, though, because I also do iOS development. Is there another solution? Perhaps installing a non-Xcode toolchain?

I tried downgrading to Xcode 10.3, but now I get an additional error: :confused:
