作業メモ
  • Install  git  , to conveniently download the OpenWrt source code, and  build tools  to do the cross-compilation process: 
    apt-get update
sudo apt-get install git-core build-essential libssl-dev libncurses5-dev unzip
    Some feeds might not available over git but only via  subversion  (short:  svn ) or  mercurial . If you want to obtain their source-code, you need to install svn and mercurial as well: 
    sudo apt-get install subversion mercurial
  • for information about the build tools see  make  and build-essential
  • for information about git see  git(7)
  • for information about the subversion tool see  svn  and subversion documentation (multiple languages)

  • Download the OpenWrt bleeding edge(trunk Version) with  git  (see Downloading Sources for more options!): 
    git clone https://git.openwrt.org/openwrt/openwrt.git
    this creates a directory 'openwrt', which is the OpenWrt Buildroot build-directory  the OpenWrt toolchain "OpenWrt Buildroot"is included
  • (optional) Download and install all available "feeds"(see OpenWrt Feeds for more options!): 
    cd openwrt && ./scripts/feeds update -a && ./scripts/feeds install -a
  • Make OpenWrt Buildroot check for missing packages on your build-system using one of the following commands: 
    make defconfig
make prereq
make menuconfig
    There you will need to select what you want to compile.
  • Proceed with build (i.e. cross-compile the downloaded sources to binaries) After the cross-compilation process the ''trunk''-directory contained 244,451 files with a total size of 3.2GiB!
