I'm building an external (my very first one) and it's working as expected, only the arguments I type when I create it are not passed and the variables set to get values from these arguments are set to zero.
The new instance routine prototype is this:
void *tabPowSine_new(t_symbol *s, short argc, t_atom argv)
and in this routine I type the following two lines:
if(argc >= 1) { x->x_frequency = atom_getfloatarg(0, argc, argv); }
if(argc >= 2) { x->x_power = atom_getfloatarg(1, argc, argv); }
but if I create an object like this [tabPowSine~ 220 0.5], the variables x_frequency and x_power (declared in the object structure) won't get these values. As soon as I send a signal or float to the respective inlet, everything works fine.
Also, I get a warning when I type "make" in the terminal, to make the Pd object, which is:
tabPowSine~.c:60:32: warning: unused parameter 's' [-Wunused-parameter]
