制作静态交叉工具链-优快云博客

本文链接：https://blog.youkuaiyun.com/valenteli/article/details/147062112
本文主要讲如何构建静态的交叉工具链，主要注意地方是 binutils构建 LDFLAGS参数是 "--static",注意是两个 -。编译 gcc的时候 LDFLAGS 参数使用 "-static"，注意是 1个 -。
#!/bin/bash

function init() {
  echo "Clean cross-tools and builddir"
  rm ${CROSS_TOOLS} -rf
  rm ${BUILDDIR} -rf
  install -d ${CROSS_TOOLS}

  mkdir -p ${BUILDDIR}
