The question is, which PR goes first :)

[teeminus]

Did someone else has trouble building? I get the following gn error:

C:\ucw\build\src>"out\Default\gn.exe" "gen" "out\Default" "--fail-on-unused-args"
ERROR This tool specifies runtime_outputs.
This is only valid for linker tools (rust_staticlib doesn't count).

  win_toolchains("x86") {

At first I thought it was due to the DEPS PR (which I tested and which did not fail), but I get the error now even when I try to recompile 127.0.6533.72 without the DEPS PR changes - which just compiled successfully in the CI. I have not yet tried compiling using the tarball but I would guess that this will work.

UPDATE: Building from tarball does indeed work.

Were you using the clone script for the builds that failed? If so were you using --keep-contingent-paths? Maybe there's something it's not downloading that should be.

[teeminus]

I do use the clone script but I also tried to compile the previous release without the DEPS changes and it failed as well.

[Ahrotahn]

One idea you could test is to skip the windows-specific pruning. Maybe that list is removing something needed for the build.

[teeminus]

We need the pruning, otherwise the additional downloads can't be extracted as some target files are (already) present.

I am currently comparing the tarball with the clone script, hoping that this will show what's wrong.

[Ahrotahn]

third_party/instrumented_libs and third_party/rust-toolchain were two of the biggest differences I can recall. The first one we had in .72 so maybe there's something needed in the rust-toolchain path. You could try removing the line for that path in the pruning script to see if there's any difference.

[teeminus]

It just fixed itself... While tinkering around I restarted compiling from scratch multiple times and now it's working without me changing anything...

[teeminus]

Turns out I need an older version of GN to build successfully when using the clone script. I need to further investigate that problem later...
