Following the tutorial on http://www.waitingforthefuture.org/2009/12/25/compiling-tcpdump-for-tomato-firmware/, I tried to compile tcpdump. I did the compilation on an Intel Pentium 4 2.26Ghz computer running Ubuntu 10.04.
My router uses a BCM3302 V2.9 CPU. However, when I run tcpdump on it, it says "Illegal instruction".
Why does this happen? What other configuration must I do before compilation?
