<direct.h> not found from /Qt/5.9.1/mingw53_32/mkspecs/win32-g++/qplatformdefs.h

I am trying to compile this library, which worked perfectly on linux (Qt5.7) but when doing so under windows (Qt5.9.1), I get a strange error that the included 'direct.h' in /Qt/5.9.1/mingw53_32/mkspecs/win32-g++/qplatformdefs.h cannot be found. Any suggestions?

So far, thw windows installed Qt5.9.1 has always worked for all my other projects...

hi @ModelTech,

the library has not been updated since 3 years, so it's likely that it won't compile with newer Qt's.

have you seen the (still open) pull request? it contains build fixes for Qt 5.8, maybe they help you.

regards

I fixed the bug as they suggested there, which enables to compile it on Linux, but the windows compilation seems to get stuck on a qt problem as the <direct.h> is included in a windows-specific qt platform file qplatformdefs.h. So, I would guess this is not necessarily directly related to the library being outdated but I could be wrong :?

Well, I have solved this one problem by adding extra version numbers to the QtOfficeOpenXml.version.in file that is somewhere in the package, but now I run into linking issues:
