Re: [edk2-devel] Error building Python

["Brian Richardson" <brian.richardson@intel.com>]

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?

Subject: [edk2-devel] 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.
