But I'm still stuck, after I followed the suggestions and added the paths via Visual Studio: Additional Include Directories: C:\local\boost_1_58_0 Additional Library Directories: C:\local\boost_1_58_0\libs When I built QuantLib in VS, I can see my C:\local\boost_1_58_0 is among the included paths. I also can see the config.cpp file in C:\local\boost_1_58_0\boost. Nevertheless I still got the C1083 error. Have been stuck for 2+ days, I'm puzzled how to get around this. Could you help? Thanks much in advance!" Support Requests closed To Be Determined None Boost 1.58.0 Showstopper invalid
