I built the mongo-c-driver 1.23.3 using VS2013. Then I built the mongo-cxx-driver 3.7.1 using the following cmake commands, all on a Windows 11 system:
cmake … -G “Visual Studio 16 2019” -A x64 -DBOOST_ROOT=C:\local\boost_1_82_0 -DCMAKE_PREFIX_PATH=C:\mongo-c-driver -DCMAKE_INSTALL_PREFIX=C:\mongo-cxx-driver
cmake --build .
cmake --build . --target install
Now when I try to build the code from the tutorial I get link errors. I haven’t found anything to tell me what I may have done wrong or how to resolve this problem. I added the include folders C:\mongo-cxx-driver\include\bsoncxx\v_noabi and C:\mongo-cxx-driver\include\mongocxx\v_noabi. I added the link folder C:\mongo-cxx-driver\lib as well.
Any help would be appreciated.
