Hi All,

Did any one faced same issue earlier?

Can you please suggest a way to build python package for edk2 basetolls. I am working a small application which I can use to read the capsule file data using python package.

Below is the sample code which I want to use:

import efilib

import struct

def dump_hii_knobs(capsule_path):

    with open(capsule_path, 'rb') as f:

        data = f.read()

    image = efilib.FirmwareVolume(data)

    hii_handles = []

    for section in image.get_sections():

        if section.type == efilib.SECTION_GUID_DEFINED:

            if section.guid == efilib.HII_DATABASE_GUID:

                hii_handles.append(struct.unpack("<Q", section.body[:8])[0])

    for handle in hii_handles:

        hii_db = efilib.HIIDatabase(image, handle)

        print(f"Knobs for handle 0x{handle:x}:")

        for knob in hii_db.get_knobs():

            print(f"\t{knob.guid}, {knob.name}, {knob.type}, {knob.default}, {knob.current}")

if __name__ == '__main__':

    capsule_path = '/path/to/capsule.cap'

    dump_hii_knobs(capsule_path)

Subject: edk2/basetools python package build is failing.

Hi All,

I am trying to build edk2/basetools python package but it is failing with the below error, looks like there is some problem with environment setup.

Can some one please suggest a way to build it?

Repo Link: https://github.com/tianocore/edk2-basetools

Steps to build:

1. Run pip install -e . (you might need do this from an admin prompt in windows)
2. Run edk2_build to make sure it works
