error on installing

[betNull]

I'm running ejabberd 18.09. On install I get an error:

/opt/ejabberd-18.09/bin/ejabberdctl module_install mod_read_markers /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/hg_read_markers.erl:6: Warning: export_all flag enabled - all functions will be exported /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers.erl:12: can't find include file "ejabberd.hrl" /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers.erl:177: undefined macro 'TDICT' /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers.erl:3: Warning: undefined callback function mod_options/1 (behaviour 'gen_mod') /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers_sql.erl:8: can't find include file "ejabberd.hrl" /opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers_sql.erl:3: Warning: behaviour mod_read_markers undefined Error: {compilation_failed,"/opt/ejabberd/.ejabberd-modules/sources/ejabberd-contrib/mod_read_markers/src/mod_read_markers.erl"}

Comment the include:

%%-include("ejabberd.hrl").

Change the TDICT to dict :

-spec affiliations_to_jid_list(dict) -> map().
affiliations_to_jid_list(dict) ->
  lists:foldl(fun({{User, Host, Resource}, _Aff}, Map) ->
                Jid = jid:make(User, Host, Resource),
                maps:put(bare_jid(Jid), Jid, Map)
              end, #{}, dict:to_list(dict)).

I hope this will help
