I tried building gRPC v1.4.0 with Visual Studio 2017 and I encountered the
following error, any ideas? I am using a slightly modified version of the
following script to perform the build (the slight modifications were to
target vs 2017). This build procedure worked fine for grpc v1.0.0. The
problem is only a warning but the build project is set to stop on warnings.
I'll temporarily change the compiler settings for both the grpc++ and
grpc++_unsecure projects (the generic_stub.cc is present in both projects)
to not treat warnings as errors (/WX-), however it would be preferable to
fix the underlying problem.
