I think recompilation is not needed .. You can pass --dfb:video-phys=0x83000000 and --dfb:video-length=691200 , but it is not causing problem that you have posted , I think its problem of installation path , just check your path in /usr/lib/directfb-1.4.3/system or similar to that , you should check one more thing libdevmem.so is present there or not .
