I am trying to implement openssl code I found into my project but I get these linker errors that aren’t going away. I checked that the frameworks are properly linked and even included the library and header search paths manually using ../lib and ../include. Despite this the error goes away when I get rid of the Openssl function or any function calls such as EVP_OpenUpdate or EVP_OpenInit. This only if I create and then call the function from my ViewController.h file for some reason.
Here is the log of the error:

Please let me know what I should do in regards to this error.
Thanks in advance.
I had to rebuild the entire project from scratch in order to get it to work. I don’t know why I had to do such a thing though.
