title: Installed OpenSSL, no openssl.h file
body: <p>I have found an answer to a question on this site, which I have tried to implement from <a href="https://stackoverflow.com/questions/918676/generate-sha-hash-in-openssl">here</a>.</p>
  
  <p>I downloaded and installed openssl from <a href="http://www.openssl.org/source/" rel="nofollow noreferrer">here</a>. I performed each step mentioned within the install text inside the extracted file. </p>
  
  <p>$ ./config
    $ make
    $ make test
    $ make install</p>
  
  <p>These all finished without error. Then when I tried to compile the code on how to generate an SHA hash using the example code from the answered question, I am given the following error:</p>
  
  <p>fatal error: openssl.h: No such file or directory</p>
  
  <p>Do I have to do something more to create the openssl header file, as I thought after installing openssl without any problems it would be automatically created? This is the first time I am adding a library to C, so please excuse any naiveties on my part.</p>
  
  <p>Thanks for reading. </p>
