Hi, CVS now contains the new compilation files that make use of Overflow's overflow-config script. About the running problems: > 2.95.2 > Standard compiler for Debian potato (stable) system. Should I get a new gcc? I use gcc 2.95.3 with is the latest, and it has the same problem with Oveflow. > PL: error in loading shared libraries: libflow-0.5.so: cannot open shared Overflow isn't installed correctly, you should get libflow listed in a ldconfig -p dump. When it isn't there , the system (linux) can not find the library, and so cant any application. That's why 2 of the 4 layers of Piper wont run for you, and you'll have the other 2 not working too ;) Jarl
