Chromium for Ubuntu 20.04

[MauryG5]

Hi, I have already written in another post what happens to me trying to build Chromium and the same now I do in this new post by Chromium on Power. I am trying to build it for Ubuntu 20.04 and to do this I am using the Guide on Raptor's Wiki who now takes care of the support for our Power systems. Arriving at the part where the LLVM/Clang compiler must be used, as soon as I execute the command:
Export clang_svn_revision =, I should put the number he wants to see but when I go to look for in the link where the guide says to go, what I find is never corrected. I tried to do differently using:
$ git clone https://chromium.googlesource.com/external/github.com/llvm/llvm-project
$ Git Checkout LLVMORG-20-INART-9764-GB81D8E90
But going ahead I was unable to make it adequately work. I would like to understand what is now critical in the part of the guide who takes care of LLVM/Clang, without this correctly part of the correct part I will never be able to go on ... does anyone have information about it?
Thank you
