meet the same problem on mac,

[ldmberman]

@iamgenchi, @oday0311 I recommend you install gcc-10, then build via CFLAGS=-m64 CC=gcc-10 AR=gcc-10-ar CXX=g++-10 ./rebar3 ...

[daocodedao]

gcc@10: The x86_64 architecture is required for this software. Mac M1 can't installed

[goomario]

Try CFLAGS="-Wno-pointer-sign -Wno-implicit-function-declaration" ./rebar3 compile

~THIS WORKED FOR ME~

God a new delayed compile error. I have no luck getting this to work. Ideas?

@fremgang you can install Erlang/OTP 23 by running brew install erlang@23 and follow the post install actions by brew.
