Bots seem fine, but a clean ToT build is failing with thousands of these:

Anyone know what's up? I don't see any recent changes there or with clang which should have triggered this. My GYP_DEFINES:

dalecurtis@xorax /d/code/chrome/src $ echo $GYP_DEFINES

component=shared_library clang=1

dalecurtis@xorax /d/code/chrome/src $ cat ~/.gyp/include.gypi

'dcheck_always_on': 1,

}

It doesn't look like Vector.h or Alignment.h includes Compiler.h. Is it possible your include path is getting you a different config.h in HTTPParsers.cpp, so you don't indirectly include wtf/Compiler.h?

Thanks for the tip. Running clang with -v showed the include paths, searching through those revealed it was pulling config.h from another third party component I'd run ./configure for :|

Hi. What was the fix?:) I have no idea how to make it NOT pull config.h from another component.

I'm currently getting the "same" error:

From your other thread, I'm guessing that the fix for you will be `rm third_party/ffmpeg/config.h`.

Wow, you're good! That did it: just deleting that config.h file, compilation continues past the error(s) - still compiling currently.

I actually remember doing a ` ./configure ` then `make` in that ffmpeg folder at some point(in the hopes it would generate that ffmpeg_stubs.h file from the other thread, but it didn't of course), and likely that is why that config.h got generated, and although I deleted what I've seen as new with git status in ffmpeg folder, some files were in .gitignore such as: /config.* so I didn't realize to they existed to clean them (well actually, I didn't think it would affect anything even if they did exist); but I should probably remove the entire ffmpeg folder and `gclient sync` to bring it back again to be sure... I'll do this if I get any more errors after this.
