error: ‘SSL_R_SHORT_READ’ was not declared in this scope
On Debian 9 64bit I installed Boost using
# apt-get install boost-all-dev
I ran cmake as follows
$ cmake -DBOOST_INCLUDEDIR=/usr/include/boost -DBOOST_LIBRARYDIR=/usr/lib/x86_64-linux-gnu -DBOOST_VER:STRING=1.62 ./
and then ran
$ make install

I made the following changes around line 310 of ./lib/websocketpp/websocketpp/transport/asio/security/tls.hpp
#if BOOST_VERSION >= 106200
if (ec.value() == boost::asio::ssl::error::stream_truncated) {
#else // older Boost supports only OpenSSL 1.0, so 1.0-only macros are appropriate
if (ERR_GET_REASON(ec.value()) == SSL_R_SHORT_READ) {
#endif
and cmake passed.
This is of course an issue in websocketpp (which many have been "fixed" already), but for those of you lowly hardware engineers like myself, I offer this as a quick and dirty fix.
Encountered the same issue today so little bump to this so others can quickly find a fix to the issue. Other solution for the less adventurous of us would be to stick with libssl1.0-dev.
I was bitten by this bug trying to compile on ubuntu18.04. Since this library doesn't seem to be maintained, I suggest looking into boost.beast.
