Hi Christian,
thanks, so I compiled the pso from cvs. Everything went fine till starting pd. There I get the erro message while loading pso.pd_linux
undefined symbol: _ZN17flext_root_singlenwEj
it seems that the pso make files aren't really up to date with flext. Please try to uncomment FLEXT_SHARED=1 in config-pd-linux.txt. This works for me.
best greetings, Thomas
