Package: libssl-dev:amd64
Version: 1.1.0c-2

Hello,

When trying to compile synergy from source
(https://github.com/symless/synergy) I get the following error:

/srv/src/synergy/src/lib/net/SecureSocket.cpp: In member function
‘void SecureSocket::showSecureCipherInfo()’:
/srv/src/synergy/src/lib/net/SecureSocket.cpp:810:46: error: invalid

  STACK_OF(SSL_CIPHER) * cStack = m_ssl->m_ssl->session->ciphers;
                                              ^~

I am using an up-to-date debian testing (stretch) distribution with
the latest kernel "linux-image-amd64 4.8+76" and libc "libc6:amd64
2.24-5"

Sincerely,
