AcompleteC/C++developmentsystemneedthefollowingcomponents

（forwindows）

1.AtmelSAM-BAIn-systemProgrammer

2.GDBServer

安装GDBServer以驱动J-Link和GDB连接。

J-Link仿真器随机光盘，安装J-Link驱动即可包含GDBServer。

3.make（forwindows）

YAGARTOmakeTools

4.YAGARTOGNUARMtoolchain（forwindows）

yagartotools，仅包括make,sh,touch等工具。

Toolchain交叉编译，包括Binutils，GCC，GDB等工具。

5.YAGARTObyEclipse-theIntegratedDevelopmentEnvironment

●aJavaRuntimeEnvironment（JRE）bySun

Eclipse是由java语言开发，且基于javaruntime的，所以需先安装JRE。

通过在windowscommandprompt界面中运行命令java-version是否显示版本号来判定安装是否成功。

●EclipsePlatformRuntimeBinary

Eclipse的本身只是一个框架平台，但是众多插件的支持，使得Eclipse拥有较好的灵活性。

许多软件开发商以Eclipse为框架开发自己的IDE。

Eclipse使用插件来提供所有的附加功能，例如支持Java以外的其他语言。

已有的分离的插件已经能够支持C/C++（CDT）、PHP、Perl、Ruby，Python、telnet和数据库开发。

插件架构能够支持将任意的扩展加入到现有环境中，例如配置管理，而决不仅仅限于支持各种编程语言。

Eclipse的设计思想是：

一切皆插件。

Eclipse核心很小，其它所有功能都以插件的形式附加于Eclipse核心之上。

Eclipse只是一个框架，在此基础上可加入java、c等的工具链（插件）才构成真正的IDE。

●EclipseC/C++DevelopmentTooling–CDT

CDT是Eclipse用于扩展Eclipse支持C/C++开发的插件。

"Help->InstallNewSoftware..."详见后。

IDE整体结构框图

 注意：

GDBdebug也可以在目标板（运行OS，例如ARM-Linux）上运行，并且通过串口或网口和宿主机上的GDB进行交互，主要用于带系统的目标板上的应用程序开发。

对于bootcode和驱动开发一般使用在宿主机上运行JTAG调试代理通过JTAG或BDM协议和目标板上的处理器交互。
