See https://www.chromium.org/developers/how-tos/run-chromium-with-flags. In
short, run Chrome or Chromium with --js-flags="--trace". Prepare to see *a
lot* of output.

Re: [v8-users] Issues Building v8 from Source

The script is failing to run a command, have you tried running the command
on its own? Maybe you don't have pkg-config installed.

[v8-users] Issues Building v8 from Source

2017-09-19 Thread Benny Mei 
Hi all,

I am attempting to build v8 from source by following the directions here
.

However, I am receiving an error on step 4, "Generate the necessary build
files by executing the following in your terminal/shell:". When executing

`tools/dev/v8gen.py x64.release`

I receive an error saying that pkg_config.gni returned with some non-zero
exit code.

Complete error log is attached.

Has anyone encountered this error before / know how to resolve?

Thanks,
Benny
