Well, I also found this zexy git https://git.iem.at/pd/zexy/ 

not sure how it compiles to objects like ==~ - coz i couldn't compile. But my colleague, Flavio, checked it out, and seems to have realized about the trick to compile an object as "==~". We did it and I compiled it for Mac Os and it is working.

By the code from the git above as a model, we changed the original code from:

void equals_tilde_setup(void)
{ 
equals_class = class_new(gensym("equals~"),
(t_newmethod)equals_new, 0,
sizeof(t_equals), 0, A_GIMME, 0);
sic_setup(equals_class, equals_dsp, SIC_FLOATTOSIGNAL);
}

To:

void setup_0x3d0x3d0x7e(void)
{
equals_class = class_new(gensym("==~"),
(t_newmethod)equals_new, 0,
sizeof(t_equals), 0, A_GIMME, 0);
sic_setup(equals_class, equals_dsp, SIC_FLOATTOSIGNAL);
}

void setup(void){
setup_0x3d0x3d0x7e();
}

Then the compiled object can be named as ==~ and it loads fine here. Should I expect that it loads just fine in any other OS as well?

cheers
