DS220j 安装gcc

背景：

近来学习了一下ARM64的neon编程，想找个硬件实际测试一下。发现我的群晖DS220j就是基于ARM64的，原本是用android-ndk-r25c\toolchains\llvm\prebuilt\windows-x86_64交叉编译的，结果发现编出来的a.out 无法运行，显示“-sh: ./a.out: No such file or directory” 。所以就想着直接在DS220j上装个gcc。

过程：

参考了这篇文章 

群晖ds216j 安装gcc | FelixBlog

首先当然是通过ssh登录DS220j了，此处略过。

后面步骤

1. 切换到root账号

sudo -i

2. 切换到临时目录，下载一个脚本 buildroot-armeabihf-bootstrap.sh，并添加可执行权限

cd /volume1/@tmp
wget http://ipkg.nslu2-linux.org/optware-ng/bootstrap/buildroot-armeabihf-bootstrap.sh .
chmod +x buildroot-armeabihf-bootstrap.sh

3. 执行脚本

./buildroot-armeabihf-bootstrap.sh

这步sh执行特别特别慢，因为下载速度实在太慢了。我没有弄代理，所以下载了一夜。大家做好心理准备。

执行结果

root@DS220j:/volume1/@tmp# ./buildroot-armeabihf-bootstrap.sh
