Erlang: Solving undef Error
http://www.richvigorito.com/code/erlang-solving-undef-error
Sometimes you'll get this error:
Error in process <0.37.0> with exit value: {undef,[{file,some_function,[]}]}
From erlang site we get this def:
"undef: The function cannot be found when evaluating a function call."
Things to check out:
1) obviously is it defined, perhaps misspelled correctly?
2) are you exporting it correctly?
ie -export([some_function/0]).
Other thing you might want to check out that aren't always as straight forward
1) if this is from an included package are you including correctly and/or is the pathing correct?
2) if this is a function you created does you're file compile correctly?
