The DLL's are not saved on the PPC.
When you developp on the PPC you must load the needed DLL's from the desktop into the folder where the source code is.
On the desktop the DLL's are in
C:\Program Files\Anywhere Software\Basic4ppc Desktop\Libraries
The best way is to beginn your coding on the desktop, in a common folder as described in the link above, save the source code in this folder, load the different DLL's you need, they are automatically saved in the same folder.
After synchronization you have all you need on the PPC.
