[edk2-devel] edk2/basetools python package build is failing.

[Jain, Vikas]

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)

Regards,
Vikas

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?

  1.  Run pip install -e . (you might need do this from an admin prompt in windows)
