Cross compiling how it works with dependencies Arm9 cpu
 

I'm a newbie when it comes to embedded linux / cross compiling. Never had to have anything to do with it b4 I bought my NAS. The Nas only has a 500MHZ ARM9 so compiling anything is painfully slow. Also only has 128MB ram. I managed to cross compile the kernel but am not sure how would you cross compile something like HPLIP for example. It has dependencies. How are you able to satisfy them?

I am not sure what HPILP means but as far as cross compiling is concerned it can be a tricky business. You would have to have a perfectly working toolchain in the first place. You can try out http://www.codesourcery.com/ for ARM related tool chains.
About dependencies AFAIK each of them will have to resolved in its own way, either include the required modules or tweak the .config file.
