Re: [edk2-devel] Error building Python

[phlamorim@riseup.net]

Im sending the feeback through this thread only, regards we have another
at https://edk2.groups.io/g/devel/message/39787 i believe we should keep
just this one, i read about MicroPython and the first thing i noticed is
GCC toolchain is not listed on support toolchain at the moment, but i
tried to compile anyway with the following command:
    # build -p MicroPythonPkg/MicroPythonPkg.dsc -a X64 -t GCC5

The build  finished with success, then i moved 'MicroPythonDxe.efi' and
'micropython.efi' to a fat partition to make a test using OVMF and QEMU,
the Python interpreter initialized with success too, and i just tested
basic operations like assign and basic arithmetics.

The first problem appears when i tried to use import, like in the
example of README, i tried to load 'VirtualConsoleDxe.efi' manually and
then execute 'micropython.efi' the VirtualConsoleDxe is loaded and
interpreter initialized too, but when i tried to do a "import
Lib.Uefi.uefi as uefi" the interpreter hangs and the virtual machine
rebooted.

The sockets module is not supported at the moment on MicroPython as said
on README, the application i want to make a prototype relies on network,
so i probably should build the StdLib package and try to make a
prototype with C, but its worth to notice the MicroPython is finishing
the build in current state, i want to know if sockets module will be
possible provided in a future release.

Thanks,
Paulo Amorim
