Affected versions: OTP-18.1, OTP-18.0, OTP-17.5, OTP-17.4, OTP-17.3
Component: crypto
Migrated from: https://bugs.erlang.org/browse/ERL-37

---

While OTPs >= 17.3 will build (through Homebrew) just fine on OS X Lion, running
{code:erlang}
crypto:start().
{code}
will not work.

The following exception and error report are produced:
{code:erlang}
** exception error: undefined function crypto:start/0

=ERROR REPORT==== 29-Oct-2015::05:46:30 ===
Unable to load crypto library. Failed with error:

Hi, I guess, you should to install openssl package with : $ sudo *brew install openssl*. Have a nice day. Regards, Gabor

It seems that openssl is already installed, brew gives me a warning to that effect. I believe it's installed as a dependency of Erlang actually.

Oops... Maybe ... some missing stuff (openssl headers) at a previous step. Did you have CLT (Xcode tools)  at the 'first' install? Could you try this:
*$ xcode-select --install*
*$ brew reinstall erlang*
Regards, Gabor

I did have the command-line tools for both installs.

Oh... Maybe... your issue is related with brew packages?! - You may ask someone from brew community. -  My N+1 tip is: You can compile Erlang from source with crypto module top on OS X, It is working fine. Regards, Gabor

Strange, it does in fact work when compiling from latest sources. Thanks so much!

Since this is an old version of OSX and the reporter seems to have succeded building we will close this issue.
