lsquic: handshake: handshake: error:00000001:invalid library (0):OPENSSL_internal:unknown library

Hi, I know this is so dummy question and I am sure it’s my fault but I can’t manage to solve it. I am trying to write simple client and server. Client will send message and server will print it out. My problem is that I cannot perform handshake and I can’t get why.

The client log output is

What I am worried about is handshake: handshake: error:00000001:invalid library (0):OPENSSL_internal:unknown library. I am not sure if I am linking library in a proper way. I have also tried to init ssl library with CRYPTO_library_init or OPENSSL_library_init or something similar but it doesn’t help. Also AFAIK this is not needed or at least it should be needed in my case.

Logs from server are:

It looks like it doesn’t event receive anything.

My code is available here https://github.com/qssh-mt/lsquic-demo

I know it isn’t complete but I just wanted to test handshake. After this I will try to implement the rest.

I would be so grateful if you could look at it.
