This project is based on original rt-n56u with latest mtk 4.4.198 kernel, which is fetch from D-LINK GPL code.

Enhancements in this repo

• commits has beed rewritten on top of hanwckf/rt-n56u repo for better history tracking
• Optimized Makefiles and build scripts, added a toplevel Makefile
• Added ccache support, may save up to 50%+ build time
• Upgraded the toolchain and libc:
  • gcc 13.2.0
  • musl 1.2.4
• OpenWrt style package Makefile
• Enabled kernel cgroups support
• Fixed K2P led label names
• Replaced udpxy with msd_lite
• Replaced Web Console with ttyd
• Upgraded libs and user packages
• And a lot of package related fixes
• ...

Compilation steps

• Install dependencies

  # Debian/Ubuntu
  sudo apt install unzip libtool-bin ccache curl cmake gperf gawk flex bison nano xxd \
      fakeroot kmod cpio bc zip git python3-docutils gettext automake autopoint \
      texinfo build-essential help2man pkg-config zlib1g-dev libgmp3-dev \
      libmpc-dev libmpfr-dev libncurses5-dev libltdl-dev wget libc-dev-bin

  Optional:
  • install golang for building go programs

    sudo rm -rf /usr/local/go
    curl -fsSL https://go.dev/dl/go1.20.10.linux-amd64.tar.gz | sudo tar -C /usr/local -xz
    echo "export PATH=\$PATH:/usr/local/go/bin" | sudo tee /etc/profile.d/go.sh
    source /etc/profile.d/go.sh
    go version

  • install nodejs for building AdGuardHome

    sudo apt update
    sudo apt install -y ca-certificates curl gnupg
    sudo mkdir -p /etc/apt/keyrings
    curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
    echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_18.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
    sudo apt update
    sudo apt install -y nodejs
    node -v

• Clone source code

  git clone https://github.com/tsl0922/padavan.git

• Modify template file and start compiling

  # (Optional) Modify template file
  # vi trunk/configs/templates/K2P.config
  
  # Start compiling with: make PRODUCT_NAME
  make K2P
  
  # To build firmware for other devices, clean the tree after previous build
  make clean

Package Development

• Makefile examples
  • Makefile project
  • CMake project
• Compiling a single package (cd to trunk first)
  • build: make libs/libpcre_only
  • clean: make libs/libpcre_clean
  • romfs: make libs/libpcre_romfs
