Build
If your toolchain is installed in different place than "/sde-wgt-toolchain/...", (see Prev) please set $CROSS_PATH to your toolchain location:
$ # /sde-wgt-toolchain/... is the default toolchain location (SO YOU DO _NOT_ NEED TO SET $CROSS_PATH!) $ #export CROSS_PATH=/sde-wgt-toolchain/openwgt-dev/buildroot/build_mipsel/staging_dir/bin/ $ sh build.sh # or "sh build.sh -j4" for SMP machines
Click kernel patch
If this process led to a positive result, you can try to patch your kernel source tree with the click linux kernel patch:
$ cd .. $ cvs -d :pserver:anoncvs@cvs.pdos.csail.mit.edu:/cvs co -d click-cvs click/release/one $ # now obsolete by fixed "linux-2.6.16.13-patch" $ #svn co $BRN_SVN_REPOS/BerlinRoofNet/trunk/click/patches click-patches $ #cd click-cvs $ #patch -p1 -i ../click-patches/click-linux-2.6.16.13-patch.patch # fix some broken stuff $ cd linux-2.6.16.13 $ patch -p1 -i ../click-cvs/etc/linux-2.6.16.13-patch
If patch was successfully applied, build the modified parts again:
$ sh build.sh # or "sh build.sh -j4" for SMP machines
Now you should have a linux kernel (vmlinux), which is able to load the click router as a linux kernel module, also called linuxmodule later.
Do not delete your System.map file! You will need later for building click kernel module.
Install Kernel Modules
Prepare to create the rootfs of your later used Linux system, by copying linux kernel modules to the "right" location:
$ make modules_install INSTALL_MOD_PATH=$(pwd)/../root $ cd ..
