The -ansi flag is used for C dialect selection and it is equivalent to -std=c90. Because it goes right before -std=gnu99 it is ignored as for conflicting flags GCC always uses the last one. |

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.
