安装交叉编译工具链
执行安装
=====> Input:
linyn@linyn-VirtualBox:~$ mkdir ~/riscv64-gcc
linyn@linyn-VirtualBox:~$ chmod +x oecore-x86_64-riscv64-toolchain-nodistro.0.sh
linyn@linyn-VirtualBox:~$ ./oecore-x86_64-riscv64-toolchain-nodistro.0.sh
=====> Output:（安装路径我这边设置为/home/linyn/riscv64-gcc，可以自定义路径）
OpenEmbedded SDK installer version nodistro.0
=============================================
Enter target directory for SDK (default: /usr/local/oecore-x86_64): /home/linyn/riscv64-gcc/
You are about to install the SDK to "/home/linyn/riscv64-gcc". Proceed [Y/n]? y
Extracting SDK.......................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /home/linyn/riscv64-gcc/environment-setup-riscv64-oe-linux
设置交叉编译工具
=====> Input
linyn@linyn-VirtualBox:~$ source /home/linyn/riscv64-gcc/environment-setup-riscv64-oe-linux
验证交叉编译工具是否设置成功
=====> Input:
linyn@linyn-VirtualBox:~$ $CC -v
=====> Output:
Using built-in specs.
