I have ubuntu. I have installed scratchbox and that is all i have. Please point me to the links or tutorial to crank out an install button from scratch, say the "Hello world" program? How much linux I have, not much, limited to cp/ls and navigate around the file systems. Why dont you read up by yourself? I tried, not very successful, need help and pointers to jump start. Thanks alot, If you really really want to take a blind person thru, can we start with writing a .ded/install button to put "Hello world" on the screen N800/N810? TIA, bun
