I’ve tried installing it on mac with asdf and it failed on ssl.

asdf install erlang 22.0-rc3
Building Erlang/OTP 22.0-rc3 (asdf_22.0-rc3), please wait...
Build failed.
 ERLC	../ebin/pubkey_crl.beam
 VSN	../ebin/
 VSN	../ebin/public_key.appup
make[3]: Nothing to be done for `opt'.

make[2]: *** [opt] Error 2
make[1]: *** [opt] Error 2

But it might be the problem with asdf itself:

cat /Users/tomaszkowal/.asdf/plugins/erlang/kerl-home/builds/asdf_22.0-rc3/otp_src_22.0-rc3/lib/ssl/src/deps/ssl.d                                                                           0 ↵
asdf is self upgrading shims to new asdf exec ...
asdf: now running erlc

  ssl_connection.hrl ssl_internal.hrl \
  /Users/tomaszkowal/.asdf/installs/erlang/21.2.4/lib/public_key-1.6.4/include/public_key.hrl \

EDIT: I’ve deleted and retried building with ASDF. I am leaving the post in case someone gets the same problem with asdf.

EDIT2: Tested it on our work project. Everything seems fine :+1:

What do you mean by this? Deleted what?

I’ve deleted the entire build directory

rm -rf /Users/tomaszkowal/.asdf/plugins/erlang/kerl-home/builds/asdf_22.0-rc3/

and retried the build with

asdf install erlang 22.0-rc3
asdf list

Those two commands made it work again. I am not sure if it was an error pulling source code for the build but it never occurred again. I assume it was something on my machine.
