Is it still possible to build locally with Docker?

[michaelforged]

Hi,

Thanks for all the latest work on this project, it's very much appreciated!

I'm wondering if the local Docker build still works. I tried to run it on my fork and while it does seem like it uses the depot_tools to build v8, which I assume is the new workflow, it fails here:

/usr/bin/python -u tools/mb/mb.py gen -f infra/mb/mb_config.pyl -m developer_default -b arm64.release out.gn/arm64.release

  Writing """\
  is_debug = false
  target_cpu = "x64"
  v8_target_cpu = "arm64"
  """ to /v8build/v8/out.gn/arm64.release/args.gn.

  /v8build/v8/buildtools/linux64/gn gen out.gn/arm64.release --check
    -> returned 1

Hi @michaeltheory,

The docker build was working a few days ago but unfortunately, it's broken now because of the upstream version of depot_tools.

I'll investigate and fix it.

You can build the J2V8 (without build V8) if you do the following steps:

$ cd /path/to/j2v8
$ curl -O https://download.eclipsesource.com/j2v8/v8/libv8_7.4.288_monolith.zip
$ mkdir -p v8.out
$ unzip libv8_7.4.288_monolith.zip -d v8.out
$ python build -t linux -a x64 --docker j2v8cmake j2v8jni j2v8cpp j2v8optimize j2v8java j2v8test

I prepared a prebuild V8 static libraries to speed up the build process.

This worked great, thanks!

It's been awhile, but I tried building again and now I get /usr/local/opt/python@2/bin/python2.7: can't find '__main__' module in 'build' when I run python build -t linux -a x64 --docker j2v8cmake j2v8jni j2v8cpp j2v8optimize j2v8java j2v8test

The following command executes successfully for me.

$ python2 build.py -t linux -a x64 --docker j2v8cmake j2v8jni j2v8cpp j2v8optimize j2v8java j2v8test

I'm using the master branch.
