[PD] Is it possible to specify relative path inside pd~ object for -pddir argument ?

[Jean-Yves Gratius]

Hi,

I'm trying to specify a relative path as argument in the pd~ object 
(using -pddir flag), in order to start a specific copy of pd 
application, located in a relative path, but without success.

Did I miss any particular syntax ?

PS : I want to write a camomile VST3 plugin that launches a pd 
subprocess via pd~, and I would like to include the pure data 
distribution inside my plugin folder structure.


Thanks
