Link problems when trying to build C++ samples on Windows: unresolved external symbol

Added by Martin Honnen 6 months ago

On Windows (using Windows 10) and the C/C++ developer tools installed by VS 2019 I am not able to build the various cppTests samples, always failing to link. Example for testXPath.cpp:

C:\Program Files\Saxonica\SaxonC EE 11.1\samples\cppTests>.\build-windows.bat

Why could that be? Does the cl command have to include more files, like

That seems to fix it.

I will attach the build file I fixed to be able to get the compiling and linking to work on Windows:

Is this being tracked or fixed in a bug issue for 11.2?
