Thanks Ben. The motivation of installing ovs on Andriod is to easily control multiple interfaces (e.g, wifi and 3G). So far we have found out that wifi can appear as an eth0 interface, and 3G can appear as a ppp-based interface, for example in Nexus One Phone, the name of the interface is rmnet0. Do you think ovs can handle these two interfaces?
BTW, i have cross compiled the openvswitch_mod.ko module for Android by a little trick: run configure without cross_compile, and then modify the Makefile in datapath/linux-2.6 to add cross compile variables, and then run make in that directory, and then i can get the cross compiled kernel module and it can be installed on android. It seems ok, and this is a snapshot on my phone: <3>[105110.598785] init: sys_prop: permission denied uid:2000 name:adb.connected <4>[105178.558044] Open vSwitch 1.0.3, built Jan 24 2011 19:24:35 # lsmod openvswitch_mod 62905 0 - Live 0xbf211000 tiwlan_drv 660205 0 - Live 0xbf14f000 stp 1266 0 - Live 0xbf135000 llc 3143 1 stp, Live 0xbf12e000 # So i wonder how can test the module with the minimal cost? 2011/1/26 Ben Pfaff <b...@nicira.com> > On Wed, Jan 26, 2011 at 11:31:59AM -0800, Yongqiang Liu wrote: > > checking whether the C compiler works... no > > configure: error: in `/home/leo/android/kernel/openvswitch': > > configure: error: C compiler cannot create executables > > See `config.log' for more details. > > > > Attached please find my config.log. > > > > Does anyone has ideas to solve the problem ? > > Your compiler doesn't work.
