Hello Andrew, Thanks for replying early, If I build as root permissions, I'm facing the issue attached below. [cid:649a0851-79c1-4d1b-9a51-f29d04c4a83d] Thanks Babu P ________________________________ From: devel@edk2.groups.io on behalf of Andrew Fish via groups.io Sent: Sunday, April 4, 2021 9:10 PM To: edk2-devel-groups-io ; Pullannagari Babu Subject: Re: [edk2-devel] uefi building for fu-540 Babu, The `Build` directory is created by the build for the build output. Looks like your problem is you don’t have privilege to add a directory in `/work/git/tianocore` Did you have to use `sudo` to add the directory? Seem like you need to fix the permissions of the tiancore directory.
