i typed "make osmocon" and "make layer23" and got some output.but i did not get the firmware binaries in src/target/firmware/board/compal_e88 and in src/host/osmocon/osmocon, in src/host/layer23/src/misc and layer23/src/mobile.

instead i got files like *.o,*.c etc..

Go read http://bb.osmocom.org/trac/wiki/PreliminaryRequirements

and come back when you've completed what's asked on that page.

Cheers,

Sylvain
