I am using ctypesgen to create Python bindings to PDFium, pypdfium2.
While ctypesgen runs perfectly well on my Linux devices, I don't manage to make it work on Windows.
After installing mingw and running my bindings generation script, the resulting file only contains the library loader classes, but no actual bindings. This is the console output:

INFO: Status: Preprocessing D:\tmp\tmpjhnl1dkc.h
INFO: Status: gcc -E -U __GNUC__ -dD "-Dinline=" "-D__inline__=" "-D__extension__=" "-D__const=const" "-D__asm__(x)=" "-D__asm(x)=" "-DCTYPESGEN=1" "D:\tmp\tmpjhnl1dkc.h"

This is how ctypesgen is invoked:

ctypesgen --library pdfium --strip-build-path "D:\Users\Mara\Downloads\pypdfium2\data\windows_x64" -L .

cd pypdfium2

Just to be sure, what version of ctypesgen are you using?

Not sure whether this is of any relevance, but I get the following error messages whilst running ctypesgen on Windows:
(The output file looks correct and my test suite passes, so this seems to be harmless, but maybe it's interesting for developpers)
