>From your e-mail I gather that you built everything by hand, right? If so, make sure you ./configure ngspice like this: ./configure --with-xspice --prefix=/wherever --with-readline=yes make su -c "make install" The important flag is --with-xspice. Then, in principle, this should install ngspice properly configured to read POLY. If POLY still causes complaints, look at the file ${geda_install_dir}/share/ngspice/scripts/spinit (or somewhere close to there). Edit your spinit (SPICE init) file to uncomment the lines specifiying where to find the codemodels. HTH, Stuart
