Error building Python

Error building Python

[phlamorim]

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?

Thanks ... br
