In OTP19: Error loading "erlang_js_drv": "undefined symbol: erl_exit"

[zhaoweiguo]

Is this project still can be use now?

os:

[root@db-01 erlang_js]# cat /etc/centos-release CentOS Linux release 7.4.1708 (Core)

erl:

[root@db-01 erlang_js]# erl Erlang/OTP 19 [erts-8.3.3] [source] [64-bit] [smp:32:32] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V8.3.3 (abort with ^G) 1>

I run:

git clone git://github.com/basho/erlang_js.git make all test

It result:

I tried #51 #53 #55 #58 It still not work for me

I checked the code, it position at erl_ddll:load(priv_dir(), ?DRIVER_NAME) The params is correct, so may be the issue is from the file erlang_js_drv.so？

Can still be used with Riak, and the erlang riak supports (r16b02_basho10). Not sure about use outside Riak. Riak is being (still, one day!) changed to support erlang 20+. BUT when that happens we will be dropping erlang_js.

@russelldb btw following issue #65 I've made a fork which is a rewrite from driver to NIF - @erlang-mozjs.

What do you think about it?

@zhaoweiguo please try this one ^^^ and tell me what's your experience. It requires mozjs52 though.

@lemenkov I think it would be great to get @martincox and bet365's opinion. I think (like webmachine and lager before it) erlang_js could well be given to the community and have it's own org on github and be maintained by the community, and not the "basho" org. Plus one from me.
