一、TI xDC工具入门简介 转载来自于TI XDC工具入门简介
1.XDC(Express DSP Component)是TI提供的一个命令行工具,它可以生成并使用实时软件组件包,它包括一系列工具，这些工具可以允许你将你的C语言代码组织成类似于java的包管理方式，具有面向对象的特性，因为它还有一个名字，叫做eXpanDed C.
2.以上两图说明了XDC的工作方式：通过相关文件设定操作指令，读入源码、库文件以及已经存在的组件包最终生成可执行文件。
3.Package------XDC工作的基本单元。包括有：源码、库文件以及元数据；元数据这包含有该包的版本信息和依赖信息，以及模块（Module）信息。
4.XDC使用方法：
5.XDC需要的文件：config.bld package.bld package.xdc
Package.xdc
-------------描述该包的名称，版本信息，依赖文件，模块信息等
Config.bld
--------------描述XDC要使用的编译工具的相关信息，如不同CPU所使用的编译工具目录，每种编译工具的编译选项，连接选项等基本信息；
Package.bld
-------------------描述对于该包需要生成的平台，profile（debug，release）。通过Javascript脚本添加源码到生成执行文件的信息中。
Package.mak-------------------由XDC生成的文件，用于最终编译可执行文件。
6.XDC工作流程：
7.使用XDC所需的文件：源码、package.bld、package.xdc、config.bld。同时需要通过shell脚本将DVEVM的安装位置导出为环境变量。
各代码如下：
Config.bld样本代码:
1 + expand sourceview plaincopy to clipboardprint? 2 var MVArm9 = xdc.useModule("gnu.targets.MVArm9"); 3 MVArm9.rootDir = "/opt/DVS357/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le"; 4 MVArm9.lnkOpts.suffix = "-lpthread " + MVArm9.lnkOpts.suffix; 5 var Linux86=xdc.useModule("gnu.targets.Linux86"); 6 Linux86.rootDir = "/usr"; 7 Linux86.lnkOpts.suffix = "-lpthread " + Linux86.lnkOpts.suffix; 8 Build.targets = [ Linux86,MVArm9,]; 9 var MVArm9 = xdc.useModule("gnu.targets.MVArm9"); 10 MVArm9.rootDir = "/opt/DVS357/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le"; 11 MVArm9.lnkOpts.suffix = "-lpthread " + MVArm9.lnkOpts.suffix; 12 var Linux86=xdc.useModule("gnu.targets.Linux86"); 13 Linux86.rootDir = "/usr"; 14 Linux86.lnkOpts.suffix = "-lpthread " + Linux86.lnkOpts.suffix; 15 Build.targets = [ Linux86,MVArm9,];
Runxdc.sh样本代码:
1 view plaincopy to clipboardprint? 2 #! /bin/sh 3 # import install paths 4 # putting the first period before the shell invokation keeps the changes 5 # to environment variables set here. Otherwise, changes to environment 6 # are only within the context of the executed script 7 8 ./setpaths.sh 9 # Define search paths for included packages 10 export XDCPATH="$CE_INSTALL_DIR/packages" 11 # Define options for execution 12 export XDCBUILDCFG=$(pwd)"/config.bld 13 # Execute xdc command to make all packages 14 15 /opt/DVS357/dvevm_1_20/xdc_2_94/xdc $@ -P * 16 #! /bin/sh 17 # import install paths 18 # putting the first period before the shell invokation keeps the changes 19 # to environment variables set here.
