Hi, I need to use udoo with a desktop enabled, so i decide tro try udoobuntu 2 beta 2. It work very well, i can program Arduino Due without any problem, but unfortunately it has not the iptables module installed. So, i've try to compile just the iptables module like this: I've install the linux header for the kernel in udoobuntu2 apt-get install linux-headers-3.14.28-udooqdl I've download linux kernel 3.14.28 and move it to /usr/src, and then try to compile the entire network folder: make -C /lib/modules/3.14.28-udooqdl-04126-g356e4b8/build M=/usr/src/net/ modules Unfortunately i've received this error: root@udoo:~# make -C /lib/modules/3.14.28-udooqdl-04126-g356e4b8/build M=/usr/src/net/ modules make: Entering directory `/usr/src/linux-headers-3.14.28-udooqdl' CC [M] /usr/src/net/802/p8022.o scripts/genksyms/genksyms: 1: scripts/genksyms/genksyms: Syntax error: "(" unexpected make[2]: *** [/usr/src/net/802/p8022.o] Error 2 make[1]: *** [/usr/src/net/802] Error 2 make: *** [_module_/usr/src/net] Error 2 make: Leaving directory `/usr/src/linux-headers-3.14.28-udooqdl' So i've try to edit the Makefile in /usr/src/net leaving just netilter and iptables: Code: obj-y := nonet.o obj-$(CONFIG_NET) := socket.o core/ tmp-$(CONFIG_COMPAT) := compat.o obj-$(CONFIG_NET) += $(tmp-y) # LLC has to be linked before the files in net/802/ obj-$(CONFIG_LLC) += llc/ obj-$(CONFIG_NETFILTER) += netfilter/ obj-$(CONFIG_INET) += ipv4/ But problem still remain... root@udoo:/usr/src/net# make -C /lib/modules/3.14.28-udooqdl-04126-g356e4b8/build M=/usr/src/net/ modules make: Entering directory `/usr/src/linux-headers-3.14.28-udooqdl' CC [M] /usr/src/net/ipv4/ip_tunnel.o scripts/genksyms/genksyms: 1: scripts/genksyms/genksyms: Syntax error: "(" unexpected make[2]: *** [/usr/src/net/ipv4/ip_tunnel.o] Error 2 make[1]: *** [/usr/src/net/ipv4] Error 2 make: *** [_module_/usr/src/net] Error 2 make: Leaving directory `/usr/src/linux-headers-3.14.28-udooqdl' How can i resolve this problem? Can someone help me to compile just iptables module? Thanks
