Openwrt SDK是一個(gè)可再定位的，預(yù)編譯好的OpenWrt工具鏈，適用于在不從頭開始編譯整個(gè)系統(tǒng)的前提下，針對一個(gè)特定平臺交叉編譯單個(gè)用戶空間包。
使用SDK的原因：
為了保證二進(jìn)制和特性兼容性，針對特定的發(fā)行版編譯自定義軟件
編譯更新版本的指定包文件
使用自定義的補(bǔ)丁或者不同特性來重新編譯已經(jīng)存在的包
#-----官方文檔如下
This is the OpenWrt SDK. It contains a stripped-down version of the buildroot. You can use it to test/develop packages without having to compile your own toolchain or any of the libraries included with OpenWrt.
To use it, just put your buildroot-compatible package directory in the subdir 'package/' and run 'make' from this directory.
