MongoDB C Driver Windows unresolved external symbol

Hey guys I hope this is not a duplicate, but searched already and didn't find a similar question.

I'm trying to build MongoDB C Driver on windows 7 64bit using visual studio as described in http://mongoc.org/libmongoc/1.1.5/installing.html

cd mongo-c-driver-1.1.5\src\libbson
cmake -G "Visual Studio 10 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver"
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

cd mongo-c-driver-1.1.5
cmake -G "Visual Studio 2010 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

I did absolutely the same but on building ALL_BUILD.vcxproj for libmongoc I got unresolved external symbols, tried a lot of stuff but still reaching this deadend.

define MONGOC_STATIC in your program

By default mongoc will compile against OpenSSL if available. In this case, the reported OpenSSL version seems to be broken somehow as the code in questions only runs when it detects OpenSSL 1.0.2 and later: https://github.com/mongodb/mongo-c-driver/blob/1.5.5/src/mongoc/mongoc-stream-tls-openssl.c#L641-L656 I'm curious which OpenSSL version you have available?

mongoc also support other TLS libraries, such as the native Windows Secure Channel.

In mongoc 2.0 (when we can change the ABI/API) we intend to change the defaults from OpenSSL to the platform native implementations (Windows Secure Channel, macOS Secure Transport) rather then defaulting to OpenSSL. LibreSSL (libtls) is also supported and will be used when found.

Configuring which TLS library to use is done as the comment above mentions, passing -DENABLE_SSL=WINDOWS to cmake (or DARWIN for macOS Secure Transport).

Fixed it, used

cmake -G "Visual Studio 14 2015 Win64" "-DENABLE_SSL=WINDOWS" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"

instead of

cmake -G "Visual Studio 2010 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" "-DBSON_ROOT_DIR=C:\mongo-c-driver"
