Can't build on MacOS M1

[DavidLobster]

During "make build" I get the following error on MacOS M1: gcc: error: unrecognized command-line option '-m64'

make[1]: Entering directory '/src/vendor/nassl/openssl-1.0.2e/crypto'

The current main branch isn’t well supported on Mac OS X. You can try the experimental sslyze branch, it has fixes for this (along with a TLS code rewrite).

Thank you very much! This works for me.
Although I still had to add --platform linux/amd64 after docker run in the Makefile
