Hi Vojtech, Thanks for your answer. I downloaded the image of the SO and started to play a bit with it. I would like to do do suggestion number 2: porting libpng to HelenOS. Since I'm new at porting code I have a couple of questions: The idea would be 'rewrite' the code in order for it to use the subset of C supported by HelenSO right? that would mean for example replacing POSIX instructions with a suited equivalent. Is that correct? In that case I have another doubt, the library contains some files which easily exceed the 3K lines. This kind of task is generally done by inspecting line by line or some kind of automation can be achieved?
Thanks again!
