I'm trying to compile MicroPython 1.11 in Windows by typing make at a command prompt and I get the errors below. I tried compiling in both Cygwin 64 and in native Windows and I get the same error in both. What am I doing wrong?

Errors:

../../py/obj.h:85:17: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
{ return ((((mp_int_t)(o)) & 1) != 0); }

Hi forum admin I'm facing same issue please help us

I tried compiling in both Cygwin 64 and in native Windows and I get the same error in both

Can you explain what 'Cygwin 64' is, and 'native Windows'? I.e. which compiler version etc? And which port are you trying to build (the unix one or the windows one)?

In any case: the only thing which is completely supported and working on Windows is the windows port built with Mingw-w64 (well, and the msvc port). I.e. you need Cygwin or MSys2 with make and Mingw-w64 installed.

Other things like using Mingw or building the unix port with Cygwin's gcc aren't supported, though might build with a little bit of work.
