Build Error in Logger: logger.h:76:32: error: unused parameter 'val' [-Werror,-Wunused-parameter]

[awadell1]

I got the following error when trying to build on a Mac M1.

Any ideas on how to fix it?

Best,

Alex

Hey Alex, I'm not too sure what's happening here, but could you try running gmake with the -Wno-unused-parameter option?

Closing as stale (the m1-build-fix branch should build on a m1 mac)
