Build error using windows sln file

error C2065: 'DUPLO_VERSION': undeclared identifier

I defined that macro and then got another error:

1>FileTypeFactory.obj : error LNK2019: unresolved external symbol "public: __thiscall FileType_Ada::FileType_Ada(bool,unsigned int)" (??0FileType_Ada@@QAE@_NI@Z) referenced in function "class std::shared_ptr __cdecl FileTypeFactory::CreateFileType(class std::basic_string<char,struct std::char_traits,class std::allocator > const &,bool,unsigned int)" (?CreateFileType@FileTypeFactory@@ya?AV?$shared_ptr@UIFileType@@@std@@abv?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@3@_NI@Z)

I am building from the sln file in the downloaded zip

I don't care about Ada support so I commented out lines 27 and 28 in FileTypeFactory.cpp and then it was able to build.

Yeah I don't keep the solution and vcxproj files updated. You can just add the missing file to the project file then it will compile (presumably, since there's nothing special about Ada support, see it's missing here).
If you do then you could add a PR for both fixes and become a contributor. Thanks!
