Shiny new Mac Studio. Installed Erlang using `kerl` as usual. Noted crypto module (as well as unixodbc and the usual wx) failed. I could probably have coped with those omissions in the short term except that rebar3 requires the crypto module. So, has anyone else trodden this path and have a recipe to follow to get OpenSSL built for darwin-arm64 and hence Erlang/OTP to build the crypto module? ---

There is a lot of discussion about what to do in the kerl issue [Can't install Erlang-24 due to openssl issues · Issue #371 · kerl/kerl · GitHub](https://github.com/kerl/kerl/issues/371) ---

Turns out all the work has been done by the OTP and kerl teams, all that is left is the OpenSSL install. I used the following runes: ```erlang git clone git://git.openssl.org/openssl.git cd openssl export MACOSX_DEPLOYMENT_TARGET=12 ./Configure enable-rc5 zlib darwin64-arm64-cc no-asm make make test sudo make install ``` Then installed Erlang & rebar3: ```erlang ~/bin/kerl build 25.0-rc2 25.0-rc2 ~/bin/kerl install 25.0-rc2 ~/kerl/25.0-rc2 . ~/kerl/25.0-rc2/activate rebar3 local install ~/.cache/rebar3/bin/rebar3 shell ``` Success! ```erlang ===> Verifying dependencies...

I am getting an error building erlang 24.3.3 using `kerl` I followed the above steps to compile and install `openssl` and then used `kerl` to install erlang. ```erlang kerl build 24.3.3 24.3.3 -n Extracting source code -n Building Erlang/OTP 24.3.3 (24.3.3), please wait...

Just an update. I set the KERL\_CONFIGURE\_OPTIONS as `export KERL_CONFIGURE_OPTIONS="--without-wx --without-javac"` Used `asdf install erlang 24.2.2` and it installed erlang successfully. Was so happy to see that as I have spent most of the day yesterday and today trying various different options. ---

For some reason I always have trouble with kerl or asdf 🤷 I just built OTP-25-rc3 sans kerl or asdf and it just worked ™ I’m just adding this comment for the record. Also, jealous of your M1 studio 😛 ---

wxWidgets 3.1.6 contains changes that broke Erlang’s wx binding. The issue was reported [here](https://github.com/erlang/otp/issues/5893) and fixed [here](https://github.com/erlang/otp/pull/5912). So if you want wx you either need to apply that fix, or rollback your wxWidget version (or wait for a release that fixes the problem).
