问题
I have a Visual Studio 2015 C++ project which I wanted to upgrade to VS 2017. I had already denied the automatic prompts to upgrade my project when I first opened my project in VS 2017 (wasn't sure I wanted to upgrade at the time) so I couldn't update my project that way. Instead, I just went to my project's:
Properties->Configuration Properties->General
And in there I updated the 'Platform Toolset' option to 'Visual Studio 2017 (v141)' and also changed the 'Window SDK Version' to 10.0.16299.0 from windows 8.1. After performing this manual upgrade I now get the warning when building:
Unknown compiler version - please run the configure tests and report the results
Why am I getting this warning? I thought by changing the 'Platform Toolset' to VS2017 I would be using the VC2017 compiler. How do I fix this warning?
回答1:
This line is from boost/config/compiler/visualc.hpp so the solution would be to upgrade to the boost 1.65.1 which properly acknowledges new version of Visual C++ compiler.
