Hi.
Please help me.
My problem:

Hi Michael.
I went through all the steps on the instructions but error still here

root@server:/opt/v8# tools/dev/v8gen.py x64.release

Hint: You can raise verbosity (-vv) to see the output of failed commands.

Do you have a thought ?

Hmm, can you please create a bug report at https://bugs.chromium.org/p/v8/issues/entry and include the following information:

1.) Commit hash that you are trying to build
2.) Platform
3.) Exact steps you used until you reached "tools/dev/v8gen.py x64.release"

Cheers,
Michael
