riscv-gnu-toolchain下载安装

克隆riscv-gnu-toolchain源码

riscv-gnu-toolchain项目在github上，在国内的主机上clone会出现很慢的问题。幸好gitee帮我们想到了这一点，可以从gitee clone下来。

[tools_adm@computing-host-001 tmp]$ git clone https://gitee.com/mirrors/riscv-gnu-toolchain.git

然后，也需要将submodules也clone下来。但由于这个仓库是从github直接mirror过来的，submodule的配置文件也指向了github地址，直接clone的话也会遇到慢的问题。我们将它修改指向gitee mirror对应的地址。

[tools_adm@computing-host-001 tmp]$ cd riscv-gnu-toolchain/
[tools_adm@computing-host-001 riscv-gnu-toolchain]$ sed -i 's#https://github.com/riscv-collab/#https://gitee.com/mirrors/#g' .gitmodules
[tools_adm@computing-host-001 riscv-gnu-toolchain]$

后记

还有几个submodule是外网的，需要手动mirror一下，再指向mirror地址。
