compile error for MIPS

Hello Mike,

thanks for your reply. For better understanding: I try to realize this 
idea: I use for internet & phone the router Fritzbox 7312. A dect-phone 
(Gigaset) is connected to this router. There is an alternative firmware, 
called 'Freetz' ( I want to use the freetz-package 
'Callmonitor' (, which has 
included an internet-reverse-search for the names for incoming calls. I 
try to transfer that name to the dect-phone.

I'm not a programmer, only a 'standard' user. My idea is to trace the 
communication between the two involved processes 'telefon' and 
'dect_manager' ( via 
an unix-domain-socket file. Is the string '\32\0`\200\0\0\20\fKein Bier 
vor 4\0\0\0' the protocol, that I could use in an own application (send 
own text to 'dect_manager')? Unfortunately, the router's vendor doesn't 
provide any information about telephony.

Best regards,
