[Doxygen-users] Building doxygen from source in VS2017 fails with: "error C2280: attempting to reference a deleted function"

[Eric E. <eri...@hs...>]

Hello

I am trying to build doxygen from source on Windows using Visual Studio 2017.  The build fails with the following error message:

5>doxycfg.vcxproj -> C:\erik\projects\doxygen\build17\build\lib\Debug\doxycfg.lib
6>C:\ projects\doxygen\doxygen-1.9.5\src\docbookgen.cpp(632): error C2280: 'DocbookDocVisitor::DocbookDocVisitor(const DocbookDocVisitor &)': attempting to reference a deleted function

Any idea what I'm doing wrong?
