Hi, In message <CANFqjkLsqy_2z7TvZhap+8xBvx8VKBnmkNuq0KY6iJ8m3f+DPw@xxxxxxxxxxxxxx> on Sat, 8 Jul 2017 11:19:57 +0200, Raymi Coevan <raymi.coevan@xxxxxxxxx> said: ... raymi.coevan> I have dependencies on Poco and OpenSSL (1.1.0e is currently used on raymi.coevan> MacOSX and Linux), and when trying to compile using MSVC2015, I get raymi.coevan> and link error telling that libeaymt64.lib and ssleaymt64.lib are raymi.coevan> missing. I tried to find where these dependencies are defined (pragma raymi.coevan> or linkage definitions) but did not find. These libraries do not look raymi.coevan> to exist since I cannot find them on MacOSX and Linux either. Yes, the libraries have changed name for 1.1.0, with names that are more in line with the Linux / MacOS X names. raymi.coevan> I have installed OpenSSL environment and tried using precompiled libs raymi.coevan> and headers from http://slproweb.com/download/Win64OpenSSL-1_1_0f.exe I tried that one with standard installation location (c:/OpenSSL-Win64), and here's what I found (looking for *.lib) that's relevant: c:/OpenSSL-Win64/lib/VC/libcrypto64MDd.lib c:/OpenSSL-Win64/lib/VC/libssl64MDd.lib c:/OpenSSL-Win64/lib/VC/libcrypto64MD.lib c:/OpenSSL-Win64/lib/VC/libssl64MD.lib c:/OpenSSL-Win64/lib/VC/libcrypto64MTd.lib c:/OpenSSL-Win64/lib/VC/libcrypto64MT.lib c:/OpenSSL-Win64/lib/VC/libssl64MTd.lib c:/OpenSSL-Win64/lib/VC/libssl64MT.lib c:/OpenSSL-Win64/lib/VC/static/libcrypto64MDd.lib c:/OpenSSL-Win64/lib/VC/static/libssl64MDd.lib c:/OpenSSL-Win64/lib/VC/static/libcrypto64MD.lib c:/OpenSSL-Win64/lib/VC/static/libssl64MD.lib c:/OpenSSL-Win64/lib/VC/static/libcrypto64MTd.lib c:/OpenSSL-Win64/lib/VC/static/libcrypto64MT.lib c:/OpenSSL-Win64/lib/VC/static/libssl64MTd.lib c:/OpenSSL-Win64/lib/VC/static/libssl64MT.lib >From those, I guess you need to change your dependencies to be libcrypto64MT.lib instead of libeaymt64.lib, and libssl64MT.lib instead of ssleaymt64.lib.
