Hi Csounders!

I want to build an opcode designed with faust, using the faust2csound
script, but the resulting .so doesn't work. It's possibly related to a
post in the csound-user archives:

I'm on fedora 31.  Checked both with current git master and stable
package of csound and faust/faust-tools.

Using the simple .dsp attached to test, csound says the .so gets loaded:

        Loading command-line libraries:
           ./testonepole.so

but further down:

   ...
   new alloc for instr 1:
   null opadr[m
   [mEarly return from csoundPerform().
   inactive allocs returned to freespace
   end of score.		   overall amps:  0.00000


Thanks for any pointers.

Here are the .dsp plus .csd, plus the intermediate .cpp, and a log from
trying to compile with csound:

That error suggests that the OENTRY line for your opcode is wrong.  I do not read c++ but my guess is that the number after the name is asking for a performance or initialisation that is not provided.

Looking again you have a threads of 7 but the 2 field is null.  In the entry change 7 to 5
