Any suggestions? Thanks again.
Hi. I was trying to compile elixir_v8
that depends on your erlang_v8
and it fails with the log below.
After I changed make v8
to make
in elixir_v8/deps/erlang_v8/rebar.confg
, it works fine. I'm new to erlang/elixir and not sure, but it seems some of make targets is missing/wrongly specified in your Makefile. How is it?
[pig@localhost elixir_v8]$ mix test
(...)
===> Compiling erlang_v8
make: *** No rule to make target 'v8'. Stop.
===> Hook for compile failed!
** (Mix) Could not compile dependency :erlang_v8, "/home/pig/.mix/rebar3 bare compile --paths "/home/pig/git/elixir_v8/_build/test/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile erlang_v8", update it with "mix deps.update erlang_v8" or clean it with "mix deps.clean erlang_v8"
Sweet project!
Any particular reason to avoid a NIF in the first place, I did not benchmark but I think the ser/deser + packet_proc_loop will have a much higher overhead then a NIF call.
Also now you have rogue threads fighting for OS cores. In the NIF case, a process on an erlang scheduler would proc a V8 instance when appropriate.
Also managing the v8 contexts I assume is possible from erlang (and procing the js eventloop from erlang)? The google engineers did not make some ridiculous JS implementation that demands an event thread be given to solely it?
since http://gyp.googlecode.com/svn/trunk is broken.

finishes without error. But when I put meaningless lines in test/js/variables.js
to make its size larger, the test was failed with the following log.
