Root 6.22.06 install on M1 Mac

[Jeremy_Lu]

Hi there,

I’m trying to install root 6.22.06 (latest stable) on M1 MacBook Pro. tried either from the source or Github with instructions. I’m getting a consistent error with OpenSSL.

Hi @Jeremy_Lu ,
that’s a weeird compilation message (Can't find file '<' : No such file or directory), I am not sure what might be causing it.

However if you don’t have a particular reason for compiling ROOT from source yourself, you can install it on Big Sur via conda, Homebrew or Macports, see https://root.cern/install .

Cheers,
Enrico

I actually went ahead and installed it with Mambaforge as mentioned in one of the threads. it worked out very easily. as for that error, I have no clue what’s causing that. thanks for the reply.
