RE: Developping C application on maemo without scratchbox
Hi, >Hello, > >I'm trying to run a simple program on my device nokia N800, >without scratchbox and it doesn't work!! First of all what are you trying to do? Are you trying to set up compilation environment on the device in order to be able to compile programs without scratchbox? This is very complicated thing to do. The reason is simply that the development libraries, gcc etc. takes a lots of space and you may be in trouble in trying to fit that on the internal flash. This would be pretty cool thing to have if there was plenty of resources on the device to allow that, but with the restrictions the device sets, it is going to be hard and I am not sure if you was going to attempt this. Or maybe you trying to do something else like execute your hello.c on your device. If the case is the latter, it sounds like you don't have your compilation environment, in other words, Scratchbox, correctly setted up on your PC and you are trying something else which will not work. > It tells me >Permission Denied when I use ./, after doing chmod +x, and I >can't use gcc to run it !! I guess you know gcc is not used to run c-programs but to compile them to machine language. The C is compiled language and is not an interpreted language where you could run something with gcc. I hope you are not meaning chmod +x hello.c and then attempt ./hello.c which will of course never work. > I already install a gcc package >gcc3.4.4, but I don't have the possibility to use it! Where did you install it? On the device or on your computer? >Please could someone help me!! >Thank you very much for reply!! If you want to do a simple C application for N800, you have to: 1. install scratchbox according to the instructions on the Meamo site 2. install rootstraps according to the instructions on the Maemo site 3. _Inside_ the scratchbox on arm-target, compile your program, for example: gcc hello.c -o hello 4. Copy your compiled executable to the device by e.g. copying to the memory card. 5. Go to x-terminal and cd e.g. /media/mmc2/ (depending on which memory card you did put your file, is it in the internal slot or on the external slot) 6. Then you can execute your hello by typing ./hello And surely it works and it doesn't say "Permission Denied". It can say this if you haven't compiled your binary properly, e.g. if you have compiled in on the PC without the cross compilation environment, namely Scratchbox.

Well the scratchbox is not used to run applications in the device, it's used to develop applications outside the device. > It > tells me Permission Denied when I use ./, after doing > chmod +x, and I can't use gcc to run it !!
