Compile error related to a pdfium header

[Ashfaaq18]

I tried compiling this project with my own makefile and got most of the cpps compiled except for one, This cpp produces the following errors

//------------------------------------ERRORS------------------------------------------// g++ -g -Wall -I"C:\DevLibs\wxWidgets\include\wx-3.1" -I"C:\DevLibs\wxWidgets\lib\wx\include\msw-unicode-static-3.1" -I"Include" -I"C:\DevLibs\pdfium-windows-x64-v8\include" -c -o obj/PDFViewImpl.o src/PDFViewImpl.cpp In file included from C:\DevLibs\pdfium-windows-x64-v8\include/fpdf_dataavail.h:13, from Include/private/PDFViewImpl.h:20, from src/PDFViewImpl.cpp:10: C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:803:32: error: variable or field 'FPDF_RenderPage' declared void 803 | FPDF_EXPORT void FPDF_CALLCONV FPDF_RenderPage(HDC dc, | ^~~~~~~~~~~~~~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:803:48: error: 'HDC' was not declared in this scope 803 | FPDF_EXPORT void FPDF_CALLCONV FPDF_RenderPage(HDC dc, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:804:58: error: expected primary-expression before 'page' 804 | FPDF_PAGE page, | ^~~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:805:48: error: expected primary-expression before 'int' 805 | int start_x, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:806:48: error: expected primary-expression before 'int' 806 | int start_y, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:807:48: error: expected primary-expression before 'int' 807 | int size_x, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:808:48: error: expected primary-expression before 'int' 808 | int size_y, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:809:48: error: expected primary-expression before 'int' 809 | int rotate, | ^~~ C:\DevLibs\pdfium-windows-x64-v8\include/fpdfview.h:810:48: error: expected primary-expression before 'int' 810 | int flags); | ^~~ mingw32-make: *** [Makefile:48: obj/PDFViewImpl.o] Error 1 //------------------------------------ERRORS------------------------------------------//

The errors are under the pdfium header fpdfview.h. The pdfium binaries I used are the chromium/4194 version from the pdfium binaries you've linked. Any idea on what to do? happy to give more info on request
