Linux 系统移植（三）- 发现一个更快捷的开发环境配置

这里需要注意，对于Ubuntu16，Samba这样搞完运行会出错



解决办法就是添加如下命令



最后还有一个警告

这个可以不用管它

对于编译器的安装，目前来说，可以选择最新版的GNU ARM GCC
请参考网址：https://launchpad.net/gcc-arm-embedded

This PPA is an alternative to toolchain released at https://launchpad.net/gcc-arm-embedded. The source codes for both are same. Currently supports Ubuntu 10.04/12.04/14.04/14.10 32 and 64 bit.

Detailed explanations to Launchpad PPA can be found at https://help.launchpad.net/Packaging/. That website explains how a PPA is set up and how to add existing PPA and install software from it.

Here are quick steps to install toolchain from this PPA on Ubuntu before 14.04:

Step1: Inside Ubuntu, open a terminal and input
       "sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa"

Step2: Continue to input
       "sudo apt-get update"

Step3: Continue to input to install toolchain
       "sudo apt-get install gcc-arm-embedded"

To remove installed toolchain, just input "sudo apt-get remove gnu-arm-embedded".
To update the toolchain, just repeat above step2 and step3.

If it reports error message of conflict to gcc-arm-none-eabi, which is likely if upgrading from 4.x to 5+, please uninstall it first with:
       "sudo apt-get remove gcc-arm-none-eabi"

Questions should be asked at https://answers.launchpad.net/gcc-arm-embedded

Bug can be filed at https://bugs.launchpad.net/gcc-arm-embedded/+filebug. It is highly encouraged to ask question first before filing a bug.
