Hello,

I tried to compile the library using QT 5.12.0 with Mingw32 compiler I followed this steps

1 - I open the qtpdfium.pro in release mode and I downloaded the PDFIUM third-party library and add it's content to the folder

2 - I compiled and I got this error so what the problem I did to not compile so I can fix it?

I have the same bug.

It seems that part of the code that isn't supposed to be compiled is being compiled. There's a define FXM_PLATFORM which by default has QT value, it happens to govern if file containing CFX_WindowsDevice definition is included. However this only happens if FXM_PLATFORM equal to FXM_PLATFORM_WINDOWS which is not the case by default.

Question to author? What should be the value of FXM_PLATFORM on WIndows 10?????
