Chicagoboss make error for lager

Question

I am porting my web application developed in Chicagoboss from my mac to ubuntu. But when I run make on ubuntu I get the following error:

ERROR: pre_compile failed while processing /home/myname/myapp_priv: {'EXIT',{undef,[{lager,start,[],[]}, {boss_rebar,compile,4, [{file,"../ChicagoBoss-0.8.12/priv/rebar/boss_rebar.erl"}, {line,97}]}, {boss_plugin,pre_compile,2, [{file,"priv/rebar/boss_plugin.erl"},{line,105}]}, {rebar_core,run_modules,4,[]}, {rebar_core,execute,5,[]}, {rebar_core,process_dir1,6,[]}, {rebar_core,process_commands,2,[]}, {rebar,main,1,[]}]}} make: *** [all] Error 1

Am I missing something? Thanking all in advance.

This error indicates, that lager parse transforms are not present while compiling. Lager does not define functions like lager:info or lager:error directly. During compilation, it changes those calls adding line number and other useful things.

Your problem can be usually solved by moving lager before any other dependency in ./deps/boss/rebar.config or adding it as a dependency directly to your application in ./rebar.config.
