build system">build system

openwrt build system 包含了Makefile及patch ，讓使用者基於cross copmile方便建立toolchain及root filesystem

  • toolchain is the set of tools used to compile code for your system

    • gcc
    • binary utils like assembler and linker (binutils)
    • C Standard library (uClibc)

  • 以在PC(X86)產生TI ARM 板子toolchain而言

    • 由toolchan source在x86上面跑，產生x86 arm-gcc (此為corss-compile toolchain，用來compile ti arm板子上面的程式)

如何build openwrt

參考來源：OpenWrt 建置 – 使用方法
