[flext] undefined symbol

Sun Sep 26 23:04:29 CEST 2010

yes it works !!!!
there is an error in the tutorial.
to compil an external linked to flext, it"s better to follow the flext
documentation ( and not to use make ).

bash ../flext/build.sh pd gcc in the fluid directory
bash ../flext/build.sh pd gcc install

thanks a lot
Luc
