背景

        换电脑，新装了系统，此时新装的WSL系统中的ubuntu系统已经没有ubunntu18这个选项了，RK提供的环境配置方法不能直接跑通，只能一个一个的解决后使用。

配置过程

按照文档配置

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
sudo apt-get install gcc-arm-embedded scons clang-format astyle libncurses5-dev build-essential python-configparser

此时报错

oxlm@oxlm:~/workspace$ sudo apt-get install gcc-arm-embedded scons clang-format astyle libncurses5-dev build-essential python-configparser

E: Unable to locate package gcc-arm-embedded
E: Unable to locate package python-configparser

去掉libncurses-dev，gcc-arm-embedded，python-configparser继续安装，这部分功能安装完毕

libncurses-dev安装

      因为新的ubuntu中，这个库已经集成到libncurses5-dev库中，因此直接安装到那个库里面即可。

gcc-arm-embedded安装

      由于ppa:team-gcc-arm-embedded/ppa里面存储的交叉工具链只支持到ubuntu18.04，因此找不到这个工具，之后的版本，直接安装即可，安装命令如下：

wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/10.3-2021.10/gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
tar xvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2

      wget的下载链接可以到 https://developer.arm.com/downloads/-/gnu-rm 里找，默认工具链为gcc-arm-none-eabi-7-2018-q2-update-linux.tar.bz2，但这个包目前撤包了，无法弄，只能用最新的包。

把RTT_EXEC_PATH改为开机自动配置

nano ~/.bashrc

在弹出的界面的最后一行添加如下信息后保存退出：

export RTT_EXEC_PATH=/path/to/toolchain/gcc-arm-none-eabi-10.3-2021.10/bin

python-configparser安装

      ubuntu24默认的python已经升级到了python3，装不了python2，但是可以使用折中的方式实现对python2的支持，安装方法为：

oxlm@oxlm:~/workspace$ sudo apt-get install python-is-python3

编译验证

      由于github上rk开源的版本和rk内部提供的商用版对应的版本有较大差异，scons --menuconfig依赖的库有差异，在rtt官方版本使用scons --menuconfig会报错，因此就不用scons生成新配置并重新生成工程了，实际上在linux下也不需要再去生成工程，都是编译时直接通过SConscript决定编哪些文件。

      编译部分通过，但由于rk2108的烧录需要转化成img文件烧录，开源部分貌似没看到这些信息，因此暂时就没烧录进去验证了。仅仅在商业版的代码中编译烧录验证，确认无异常。
