Function "dynamic_compile:from_string" failed when start with rebar

Question

I'm using dynamic_compile to dynamic create logger. It told error when start through rebar, but correct when start normally. Please help to have a look. Here is my little demo project on github.

Following is my steps:

Step report error:

~/rebar_test > rebar compile generate
~/rebar_test > ./rel/server/bin/server console

then get error:

Answer 1

This caught my eyes:

"Error compiling logger (~p): ~p~n",
