libzrtpcpp 2.3.4 make error

I tried to make libzrtpcpp2.3.4, but getting this error
while configure is succeeding.

Code:../src/libzrtpcpp/crypto/openssl/ZrtpDH.cpp: In constructor 'ZrtpDH::ZrtpDH(const char*)':
../src/libzrtpcpp/crypto/openssl/ZrtpDH.cpp:226:15: error: invalid use of incomplete type 'DH' {aka 'struct dh_st'}
