Subject: [2021-gsoc-llvm-gnumake]: proposal for building using llvm/gnumake
Date: Thu, 12 Aug 2021 01:51:56 +0000	[thread overview]
Message-ID: <YQXPR0101MB146215160084D99ED5F854DBCDF89@YQXPR0101MB1462.CANPRD01.PROD.OUTLOOK.COM> (raw)


[-- Attachment #1.1.1: Type: text/plain, Size: 493 bytes --]

Hi,

I want to push my change to my codes to edk2-staging, yet it seems like I don’t have permission to do so:
[cid:image002.png@01D78EF8.2F469F30]

My mentor and I have enabled edk2 building using llvm+make and gnumake+clang in windows command prompt. The attached patch indicates changes we made to make this happen.

I also attach the readme file to go through the steps to build Basetools.

Please review our codes and thank you very much for your time.

Best regards,
Yuqi
