Hello.
My friend tries to install elixir into MacOS. It stops at installing erlang every time, then he tried to install erlang 23 individually, but it failed as well.

Anyone has same problem?

I have never used MacOS and brew however I recommend asdf. You can install Elixir both from source and precompiled version.

Do you know anything about this?

What version of macOS is this?

If it’s running Big Sur, that might explain it.

I’ve been using Elixir from Homebrew for over a year, and I’ve never had problems like that.

Have you looked up the mentioned log-file for full details?

Anyway, there are a lot of MacOS/Erlang combinations known to be broken for a variety of reasons. And as I do not use a Mac, I do not really keep track of those… Perhaps you can tell us what MacOS version you use, what version of XCode, etc.

His MacOS version is 10.15.6, and Xcode version is 12.0.

It is the error part of the log file. I don’t see any solutions for this…
Do you have some ideas?

It was already reported before. Please take a look at those issues:

Setting CFLAGS to -O2 -Wno-error=implicit-function-declaration fixed it for me (as described in the linked issues).
