How do I add my own opcode to the makefile now?
I used to know how to do it with the old Scons, but haven't tried it
with cmake yet.
I figure there is something I should do in cmake-gui perhaps?
Assume I have the c file in /Opcodes

Note that a plugin does not need to link with anything (unless it has dependencies of its own). So

gcc -shared myfile.c  -o myplug.  -I -DUSE_DOUBLE

should do the job on linux or windows-mingw

on OSX use -dynamiclib instead of -shared

Excellent, thanks.
Now, can I find any guidelines as to what is different when writing
opcodes for csound6, compared to writing for csound5?
I've poked around a bit and can guess some things, but I would feel
more confident with some kind of instructions.
all best

The information was in the release notes for 6.00

An extract....

The template for arate perf-pass opcodes is:

     int perf_myopcode(CSOUND *csound, MYOPCODE *p)
     {
         uint32_t offset = p->h.insdshead->ksmps_offset;
         uint32_t early  = p->h.insdshead->ksmps_no_end;
         uint32_t nsmps = CS_KSMPS;
         ...
         if (UNLIKELY(offset)) memset(p->res, '\0', offset*sizeof(MYFLT));
         if (UNLIKELY(early))  {
           nsmps -= early;
           memset(&p->res[nsmps], '\0', early*sizeof(MYFLT));
         }
         for (n=offset; nres[n] = ....
         }
         return OK;
     }


Or do you need more?

Just brainstorming, we had discussed a little bit about updating the
plugin SDK.  This made me think of a couple of things that might be
nice for the SDK:

* by default, install into the same default locations for OPCODE6DIR64
as the main build does

* have test CSD's that are pre-configured to run the plugin from the
build dir with --sample-accurate, without it, maybe other
configurations
