Hello,

This is what I get:

./rtbkit/js/bidding_agent_js.cc: In static member function ‘static v8::Handlev8::Value Datacratic::JS::BiddingAgentJS::start(const v8::Arguments&)’:
./rtbkit/js/bidding_agent_js.cc:242:20: error: too few arguments to function ‘void ev_ref(ev_loop_)’
/home/recoset/local/include/node/uv-private/ev.h:632:6: note: declared here
./rtbkit/js/bidding_agent_js.cc: In lambda function:
./rtbkit/js/bidding_agent_js.cc:248:26: error: too few arguments to function ‘void ev_unref(ev_loop_)’
/home/recoset/local/include/node/uv-private/ev.h:633:6: note: declared here

I had to add the 'loop' parameter e.g.

struct ev_loop * loop = ev_default_loop(0);
ev_ref(loop);
...

But otherwise, it seems to work. You're probably using a newer version of node.
Can you update your code please and I'll be able to merge.

Thanks!

Éric
