You might not have up-to-date Pd sources (needed for multi-instance
to work) - for instance, here's the latest:</pre><pre style="font-family: courier, 'courier new', monospace; font-size: 14px; white-space: pre-wrap; word-wrap: break-word; margin-top: 0px; margin-bottom: 0px; line-height: 19.6px; widows: 1; background-color: rgb(255, 255, 255);" class="">void clock_unset(t_clock *x)
{
if (x->c_settime >= 0)
{
if (x == pd_this->pd_clock_setlist)
pd_this->pd_clock_setlist = x->c_next;
else
{
t_clock *x2 = pd_this->pd_clock_setlist;
while (x2->c_next != x) x2 = x2->c_next;
x2->c_next = x->c_next;
}
x->c_settime = -1;
}
}
(from either 0.46 or mater branches in git) - I don't know why you'd have an
old Pd as part of libpd but the line printout below doesn't look roght.
cheers
Miller
