I am trying to hook up OpenSSL to a dlang project I'm working 
on, but I have hit a problem when trying to link.

I currently get the following linking error:

undefined reference to `EVP_CIPHER_CTX_init'

I have made sure to include the module wrapping the c headers

import deimos.openssl.evp;

And I have made sure that I am linking to "libcrypto" and 
"libssl" in my "dub.json" file. I have even pointed the linker 
to my "/usr/lib" folder

And I made sure that those libraries are installed on my system 
in "/usr/lib"

libcrypto.o
libssl.o

Here is the code that I am trying to run:

import deimos.openssl.evp

void main()
{
   EVP_CIPHER_CTX *ctx;
   EVP_CIPHER_CTX_init(ctx);
}

Here is the full verbose output of dub:

Here is my full dub.json file: https://pastebin.com/raw/1Z3WGBET

Any help would be greatly appreciated! Thank you so much!

Hi Everyone, this is not an error in D, or the OpenSSL wrapper 
code it's just me not reading the OpenSSL man pages...

EVP_CIPHER_CTX_init is not longer the way to create the context 
in 1.1.0 - It has been replaced by:

EVP_CIPHER_CTX *ctx;
ctx = EVP_CIPHER_CTX_new()

RTFM...
