米尔瑞萨RZ/G2L开发板 安装交叉编译器

安装SDK

下载sdk并上传到虚拟机，解压后执行：

在这对话框中输入想要保存的目录：

在下面的对话框中输入Y:

然后稍等安装完毕：

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.
 $ . /opt/yg2lx/environment-setup-aarch64-poky-linux
 $ . /opt/yg2lx/environment-setup-armv7vet2hf-neon-vfpv4-pokymllib32-linux-gnueabi

测试SDK

安装完成后，使用以下命令设置环境变量，测试 SDK 是否完成：

lugl@lugl-virtual-machine:~/MYD/sdk$ source /opt/yg2lx/environment-setup-aarch64-poky-linux

lugl@lugl-virtual-machine:~/MYD/sdk$ $CC -v

到此，SDK就安装成功了。

测试

用vim编写一个hello.c:

保存后编译：$CC hello.c -o hello

编译后查看hello文件类型：

lugl@lugl-virtual-machine:~/MYD/sdk$ file hello
hello: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-aarch64.so.1, for GNU/Linux 3.14.0, BuildID[sha1]=5aa9a4ba2a1ff9ca3ef36c5d5508eb448b8f85f1, with debug_info, not stripped

上传到开发板，修改权限后执行：

成功的输出了hello world，说明SDK安装成功！
