[Olsr-dev] ARM Telefon

[Sven-Ola Tücke]

Ah - sorry. Wrong list - wrong language.

Olsrd should run on an ARM CPU to my knowledge. So I have installed a typical 
build tool chain on my new Android Mobile. When I start make, there are lots 
of Warnings stating: "src/ipcalc.c:164: error: cast increases required 
alignment of target type". If I start olsrd, it shows "BUS error" after a 
short time. Well - those warnings are obviously serious.

OK - some pointer magic added to overcome the warnings. Does anybody know some 
background to this (I'm not an ARM freak). I think about something like this:
