As for RogerS question, the plucker in Maemo behaves little bit strangely. I dont know whether this behavior is normal for other devices also, but on Nokia I have difficulties to delete soemthing from the library and I cannot change fonts. But once you get to reading it feels very nice. The arrow buttons are little bit tough to press, but otherwise not a single complain.
I had this problem when I was starting out. In the tutorial it says:
In order for Plucker Viewer to add a book to its library database, the .pdb file needs to be in the MyDocs folder (or a subfolder, such as eBooks)
In the development environment the path to this folder is:
Kanotix/scratchbox/users/knoppix/home/knoppix/MyDocs
The Kernel Concepts guys straightened me out on this, and when I created the right folder everything was smooth. What folder are you putting the books in?
I'm getting closer. I used Plucker desktop and the tutorial posted on the previous page to convert a text file to plucker pdb format. This added ok to the Plucker database but when I try to view it I just get a blank page.
I suggest using a pdb file that you know can be read by Plucker -- one of those from the Plucker site, or Alice in Wonderland, or one of the other examples from Kernel Concepts. At least you should rule out it being a problem with what you're trying to read or open.
During the installation of plucker you had an option to add "convert to plucker" to txt and html file popup menus. Write a simple text file (just a sentence in english) and try to convert it.
