Synergy-core: Compilation problem on linux
I'd assume you guys are already aware of this, but couldn't find it.
Compiling on linux (4.5.0-2-amd64 #1 SMP Debian 4.5.3-2 (2016-05-08) x86_64 GNU/Linux) as of ver ade4b7f, following problem occurs:

This bugreport was filed for openssl, but apparently their api was changed, thus not their issue. Could it be on synergy side?

There's a comment above the line of that error that mentions this.
// m_ssl->m_ssl->session->ciphers is not forward compatable, In future release
// of OpenSSL, it's not visible, need to use SSL_get_client_ciphers() instead
In the short term while a version check and fix isn't merged the following replacement might work
STACK_OF(SSL_CIPHER) * cStack = SSL_get_client_ciphers(m_ssl->m_ssl);

Which version of OpenSSL are you trying to compile against?

@XinyuHou It's a version of OpenSSL 1.1 in Debian stetch (testing) and Debian sid (unstable)

I don't mean to intrude but is there a work around or fix for this? I'm running into the same issue, OpenSSL 1.1.0c
4.8.0-amd64 #1 SMP Debian 4.8.15-1 (2016-12-23) x86_64 GNU/Linux
