Erlang rr() returns missing_chunk -


newbie question on erlang using wings 3d shell (windows 7 pro, wings 3d 1.4.1). when write command read records definitons:

    rr(wings).

i error:

    {error,beam_lib,       {missing_chunk,'d:/temp/erlang/lib/wings/ebin/wings.beam',"abst"}}

what doing wrong?

rr/1 "reads record definitions module's beam file. if there no record definitions in beam file, source file located , read instead."

my guess abstract form hasn't been included in .beam file , in installation source files not available.

update: digging shell:read_file_records/2 function, i've found following:

read_file_records(file, opts) ->     case filename:extension(file) of         ".beam" ->             case beam_lib:chunks(file, [abstract_code,"cinf"]) of                 {ok,{_mod,[{abstract_code,{version,forms}},{"cinf",cb}]}} ->                     case record_attrs(forms) of                         [] when version =:= raw_abstract_v1 ->                             [];                         [] ->                              %% if version raw_x, test                             %% unnecessary.                             try_source(file, cb);                         records ->                              records                     end;                 {ok,{_mod,[{abstract_code,no_abstract_code},{"cinf",cb}]}} ->                     try_source(file, cb);                 error ->                     %% "abst" chunk missing (pre r6).                     error             end;         _ ->             parse_file(file, opts)     end.

it looks like, if "abst" chunk missing, doesn't try read source code. beam_lib:chunks(file, [abstract_code,"cinf"]) return you? erlang version running?
