We upgraded chicagoboss which has the dependency of 'bson'. When we compile the chicagoboss using ./rebar update-deps compile. While compiling the chicagoboss it throws syntax error.
But basically we pull it from 'HEAD'. I'm not sure if that is the good idea though.
Pulling bson from {git,"git://github.com/mongodb/bson-erlang","HEAD"}
Cloning into 'bson'...
Here is the compile error:
$./rebar update-deps compile

Can anyone suggest the solution?
Source of the problem is that mongodb-erlang ce9bf77902 from BossDB v0.8.15 (current ChickagoBoss) uses HEAD version of bson which is incompatible with Erlang/OTP < 17 now.
You can specify working version of bson in rebar.config before boss_db dependency. As I can see tag v0.2 is ok for R16B03-1.
