Below is the complete command used by the IDE. Please allow me to remind you that this program is a direct conversion to C from the sample, so no g++ is used. gcc.exe -c WicViewerD2D.c -o WicViewerD2D.o -I"C:/msys64/mingw64/include" -I"C:/msys64/mingw64/x86_64-w64-mingw32/include" -I"C:/msys64/mingw64/lib/gcc/x86_64-w64-mingw32/9.2.0/include" windres.exe -i WicViewer_private.rc --input-format=rc -o WicViewer_private.res -O coff gcc.exe WicViewerD2D.o WicViewer_private.res -o WicViewer.exe -L"C:/msys64/mingw64/lib" -L"C:/msys64/mingw64/x86_64-w64-mingw32/lib" -static-libgcc -mwindows -lole32 -ld2d1 Thank you. _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
