[erlang-questions] Failed to run make..

[Pavanan M S]

Hi all,

           While trying to run make in a project I encountered this message
first;-

               ===> Plugin rebar_gdb_plugin not available. It will not be
used.

           Then it crashed showing this message;-

           ===> Compiling
/home/pavanan/pine/_build/default/lib/pine/src/pine_tools.erl failed
/home/pavanan/pine/_build/default/lib/pine/src/pine_tools.erl:339: illegal
guard expression

          Looking at the code I found that the guard expression consists of
a function
*is_map(). *
          That function didn't work in my erl console (returns function not
found.).

          1. Are these errors related? and
          2. How can I make this work.
