fmode.c should only be included for builds targetting 'pure' windows, i.e. msvc or mingw builds but not when using msys or cygwin's gcc (see #2298). Just checking if the OS is windows and UNAME doesn't have msys stil leaves the gate open for builds with cygwin's gcc since UNAME there is e.g. CYGWIN_NT-6.1-WOW. Fix this by checking for 'mingw' explicitly in the compiler version; both gcc and clang have the -dumpmachine flag so the check should be ok for all platforms.
MicroPython cross compiler
This directory contains the MicroPython cross compiler, which runs under any Unix-like system and compiles .py scripts into .mpy files.
Build it as usual:
$ make
The compiler is called mpy-cross. Invoke it as:
$ ./mpy-cross foo.py
This will create a file foo.mpy which can then be copied to a place accessible
by the target MicroPython runtime (eg onto a pyboard's filesystem), and then
imported like any other Python module using import foo.
Different target runtimes may require a different format of the compiled bytecode, and such options can be passed to the cross compiler. For example, the unix port of MicroPython requires the following:
$ ./mpy-cross -mcache-lookup-bc foo.py
Run ./mpy-cross -h to get a full list of options.
