I think this is more properly a question for the openssl list, you can search the archives at http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html
(does this help?: http://openssl.6102.n7.nabble.com/version-script-td63374.html )

And failing that ask the question on the list.

Maybe it needs OpenSSL 1.0.0 anyway, even if a new version is available?
I'm using TLS sockets, so I will have to go with OpenSSL. Moreover I have to ship OpenSSL together with the application, because there is no way Android can handle this dependency otherwise.
I still don't know why this error message only pops up if Asio is integrated in my app...

Best regards
Sandra

Hi Sandra.

I think you can use any version of OpenSSL with Asio, I'm using OpenSSL 1.0.2f by the way (Standalone Asio though).
You just need to install OpenSSL libraries and link them when you compile your program.
Asio doesn't need OpenSSL at all if you don't use ssl socket.

Manh.
