[erlang-questions] Remote module compilation

[Alin Popa]

Ok, I found the solution:

(thanks to http://www.trapexit.org/Remote_Code_Load)

On the 1st node:

*1> {Mod, Bin, File} = code:get_object_code(tes).

2> {Replies, _} = rpc:call('node@REDACTED',erlang,load_module, [Mod, Bin]).
{module,area_server1}
*
and now, simply run:

*Pid = spawn('node@REDACTED', test, test_fun, []).*
*<5476.55.0>*
