Tinkering OpenWRT (5) : Build OpenWRT Source Code

Step 1: Inslall softwares

sudo apt-get install subversion g++ zlib1g-dev build-essential git python rsync man-db 

sudo apt-get install libncurses5-dev gawk gettext unzip file libssl-dev wget

Step 2: download source

git clone https://git.lede-project.org/source.git lede 

cd lede 

Step 3:

./scripts/feeds update -a 

./scripts/feeds install -a 

Step 4:

make menuconfig # Maximum the terminal when doing this.

More research needs to be done here to fit different systems. Here we compile for VirtualBox as an example.

      “Target System” ⇒ “x86”

      “Target Images” ⇒ “Build VirtualBox image files(VDI)”

Save and Exit.

Step 5: Compile
