Hi,
I encountered this myself just last week. If it's the same cause as for
myself, and it's quite likely that it will be, check if you have
multiple copies of the Xerces-C++ and Xalan-C++ libraries and headers on
your search paths. The cause is that you're using the headers from one
version, and the libraries from the other, and that these are not
compatible. Remove the old libraries and it will likely solve the problem.
I note that the function signatures all contain wchar_t. It might be
that one version of the Xerces-C++ library is using wchar_t while the
other is using char16_t as the XMLCh type.
Kind regards,
Roger

I am trying to migrate my application from VS 2010 to VS2017. My 3rd party
library includes Xalan 1.11 and Xerces 3.2.2 . While compiling one of the
projects ,I was facing the below error. While building the Xerces library I
have treated "XmlCh type as wchar_t" . It will be highly appreciated if
anyone could figure out the possible reason for the same.
