i'd like to use gre tunnel

but it seems that a gre package is not included in opkg.

i tried to configure gre tunnel :

->ip tunnel add gretun1 mode gre remote [ip] local [ip]

->ioctl : No such device

how do i install and configure the gre tunneling?

Ok, I checked the latest Processor SDK Linux and it seems it is not enabled. I am not sure if you use an official TI SDK, however try checking if the needed CONFIGS are enabled in tisdk_omapl138-lcdk_defconfig. To see which sources you need to include in the defconfig check net/ipv4/Kconfig (search for GRE in the file).

actually, i don't know kernel level well. i only use SD card offered for SGI EVM. it is Linux kernel demo v2.0.
however, i checked that i need several kernel modules such as ip_gre.ko, and brctl. I don't know how to make the modules , but I'll try to get the modules.
thank you.

Yes, as I said, you need to check your defconfig file. It should be located in arch/arm/configs/ then add:
CONFIG_NET_IPGRE=y
CONFIG_NET_IPGRE_DEMUX=y

and so on (check which modules you need in the Kconfig file). Then recompile the kernel and the modules will be built in the kernel image.
