====== Advanced build options ====== ===== Build faster ===== Build using several cores ''make -j(n+1) where n=#CPUs'', For example: make -j4 ===== Manual build ===== If you are rebuilding OpenWrt often, or don't want to use build.sh script, you can build manually. First time building or when you want your feeds updated, run: ./scripts/feeds update -a ./scripts/feeds install -a To set config to defaults: git checkout .config Then finally build: make IGNORE_ERRORS=m ===== Customize your build ===== Run this after you updated your feeds: make menuconfig to configure OpenWrt according your needs. You should see configuration window like this: {{:rambutan:gettingstarted:rambutan_menuconfig.png?nolink&|}} ===== Build custom image without compiling ===== If you need firmware image that contains packages that are not in default image, but available in [[http://pkg.8devices.com|pkg.8devices.com]] repository - use Image Builder. No cross-compiling is required so build process is fast. This example uses v2.9 release, use latest available when building. wget "http://pkg.8devices.com/rambutan/v2.9/OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64.tar.bz2" tar -xjvf OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64.tar.bz2 cd OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64/ This adds ''luci tmux kmod-fs-ntfs'' packages, contents of ''files/'' directory to image and removes ''ppp ppp-mod-pppoe kmod-pppoe kmod-pppox'' packages that are in default image: make image PROFILE=RAMBUTAN PACKAGES="luci tmux kmod-fs-ntfs -ppp -ppp-mod-pppoe -kmod-pppoe -kmod-pppox" FILES=files/ Image will be available in ''bin/ar71xx'' folder.
