Error building Python

I want to use python to prototype some UEFI applications, but the build
is not working on my environment, im trying to build in a linux(debian)
which have "gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516" installed, the
EDK2 is properly installed, i build other packages like OVMF and Mde*,
at the first time i tried to build Python just uncommenting
"AppPkg/Applications/Python/PythonCore.inf" the build stopped because
some compiler warnings which are stopping the building bcause the flag
-Werror, so i changed the file tools_def.txt to remove the -Werror flag,
the warnings dont stopped the build, i probably should fix the warnings
one by one, but when i tried to build again the build system stopped at
target
'/root/projeto_final/src/edk2/Build/AppPkg/DEBUG_GCC5/X64/AppPkg/Applications/Python/PythonCore/DEBUG/Python.dll',
i will leave the entire error message following this message, let me
know if i need to provide another/more information.

Re: [edk2-devel] Error building Python

[Brian Richardson]

Paulo:

A port of the MicroPython Interpreter for UEFI is available in edk2-staging: (MicroPythonPkg). This is a Python 3 compatible alternative for the Python 2.7 implementation in AppPkg.

Can you try this and provide feedback?

[Carsey, Jaben]

Paulo,

I would urge you to use the minpython instead of the AppPkg python.  The minpython is a python 3 implementation vs. this 2.7 implementation. New development should not start on a version of python that is about to go officially EOL.

That being said, I have not seed that error message before. Maybe Daryl has a better starting point.

Re: [edk2-devel] Error building Python

[phlamorim]

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
