you have to set:

pv_val.flags = PV_TYPE_INT;

-- hope is ok, since I tried to remember from memory. The errors shows 
that the type is considered to be string, in your case.

You can add the pv in any of the modules, does not have to be in "pv" 
module... then you can move it later. There are many modules exporting 
PVs ... htable, tmx, ...

Cheers,
Daniel
