I recently upgraded Erlang on my mac, via homebrew to R20. The first time I went to test an application using cuttlefish I received this error.<br class="">
<br class="">
Argument '-smp disable' not supported. Use "+S 1" instead.<br class="">

I wrote a trivial escript of my own and sure enough, with R19 it works fine, with R20 the above error.<br class="">
<br class="">
Here is the escript I am using for testing.<br class="">
<br class="">
#!/usr/local/Cellar/erlang@19/<a href="http://19.3.6.4//bin/escript" rel="noreferrer" target="_blank" class=""><wbr class="">19.3.6.4//bin/escript</a><br class="">

%%! -smp disable -sname demo -setcookie cookie<br class="">

-define(ME, filename:basename(escript:<wbr class="">script_name())).<br class="">
-include_lib("kernel/include/<wbr class="">file.hrl").<br class="">
<br class="">
main(Args) -><br class="">

halt(0).<br class="">
<br class="">
Cuttlefish uses {escript_emu_args, "%%! -escript main cuttlefish_escript -smp disable +A 0\n”}. in it’s the rebar.config.<br class="">
<br class="">
Thanks,<br class="">
