Conflict between two static library (.a file)

Hello, Everyone:
( Ignore my English grammar :smiley: )
I got a problem between two static library. Its said that MD5.h( and more others) included by each static library and make a conflict, Actually It’s problem with Encryption Algorithm. They both are third-party charges libraries.
How can solve the problem?
Thank you, Firstly.

There are some solutions:

  1. Ask the developers of the both libraries for a solution.
  2. Remove one lib.
  3. Search a third lib which do the same as the both others libs are doing.
  4. Is the source of the libs available make an ‘adapted’ lib
