Hallo!
I've been trying to get _pix_2pdp_ loaded for a while now, along with _gem2pdp_ etc... and end up with the following error=>
/usr/lib/pd/extra/pix_2pdp.pd_linux: /usr/lib/pd/extra/pix_2pdp.pd_linux: undefined symbol: _ZN9CPPExtern10m_holdnameE pix_2pdp: can't load library
I also just got the same undefined symbol - anyway, I also have to compile it again and will look into it this evening ...
LG Georg
