Thanks for your reply. I have already installed OpenSSL but when I install Erlang, I find that crypto is missing. And it gives me an error that OpenSSL might not be installed. Can you help me here?

Dear Thomas,

I tried different parameters and have found out that the error occurs only when the option "shared" is used in the command. It works fine for all others. Can you please explain to me what is the purpose of the shared parameter? And is it okay if I configure openssl without it?

Try removing the --openssldir=/usr/local/ssl flag. I think it is not needed.

sudo ./config --prefix=/usr/local/ssl shared zlib

Hi,

I have no familiarization with OpenSSL. I am installing it as a dependency for installing Erlang. I am using this guide:

https://www.howtoforge.com/tutorial/how-to-install-openssl-from-source-on-linux/

Version installing is openssl-1.0.2l

I am facing the following error on make [3] while configuring OpenSSL. Can someone please guide me through it:

make[3]: Entering directory '/media/erlang/openssl-1.0.2l'
make[4]: Entering directory '/media/erlang/openssl-1.0.2l'

I used the following command to configure:

sudo ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
