Not all the symbols from the pcb library are available from gschem. Only the ones linked to from /usr/X11/lib/X11/pcb/m4/common.m4 You might have to modify that file to add the parts you want. If you can't get that to work, or don't want to learn m4, you can add the symbol manually in pcb, give them the same name as your netlist (command "n") then load the netlist. Generate the netlist with gnetlist -g PCB file.sch -o file.net Bonne chance, Chris. Jacques-Charles Lafoucriere <jc.lafoucriere@cea.fr> said:Hi all, I have made a simple schema with gschem (a 68HC11 and a 32K SRAM) and I am trying to generate a netlist for pcb. I have the following issues with gschem2pcb : 1) the footprints "PLCC 52 socket" and "W-DIL 28" from the generic pcb library are not found "62256" from the memory library is not found 2) the footprints "PLCC 52 socket" is replaced by "PLCC 52" (I see a SMT footprint instead of a socket) All the footprints I have used can be used from pcb Someone can help me ?
