i'll abort this commit locally  

i've reverted it
and  
i got a new bug

https://p.teknik.io/O286j

The first issue should be fixed after
https://chromium-review.googlesource.com/c/chromium/src/+/884423

But I cannot reproduce the second issue -- after that patch, "gn gen" works fine with the args in your link.

failed   with  the original commit

with your patch  https://p.teknik.io/wW1jV

my systemlibs
https://p.teknik.io/8GjH3

libwebp 0.6.1

NEW TEST

my  revert + your patch + google webp

WORKED


GOOGLE WEBP

i'll make a last test, 

google webp yes

your commit yes

revert "bad commit" no
    

I'm able to reproduce the issue when I unbundle libwebp

The libwebp unbundle should work after https://chromium-review.googlesource.com/c/chromium/src/+/884942
Please give it a try

https://chromium-review.googlesource.com/c/chromium/src/+/884942

It should work without reverting https://chromium.googlesource.com/chromium/src/+/cb4f92cc31ff0e1e598b8e023a40a0409a766a60

Could you try applying the 2 patches, deleting everything in your out dir, and building again?

rextract tarball
redownload clang

Could you attach the build log

https://p.teknik.io/Api27

Not sure why you don't have gtest-internal.h.  I see it when I extract the tarball:

Ok, another cl:
https://chromium-review.googlesource.com/c/chromium/src/+/885006

Could you apply this 3rd CL to verify it fixes the issue

worked
