I grew impatient with the lack of an SDK for my 903. I'm sure quite a few of you have noticed that the new models - 602, 603, 902 and 903 - do not accept programs built for earlier models. The root cause appears to be a change of ABIs; the 15.1 SDK expects a /lib/ld-linux.so.2 loader but the one in the 903 is .so.3. That's probably because of a switch to EABI. So I installed an EABI system in a qemu emulator, shoved in some headers from the old SDK and libraries from the 903, tweaked a makefile.. and managed to build a program! You'll find poterm runnable for the 903 at my machine
, as well as the emulator system image in which it was built - probably usable to build other things as well. Don't forget poterm.ini if you try poterm out!
