本文介绍了XDC工具集中的关键组件，包括用于执行XDC脚本程序的xs命令、生成配置文件的xdc.tools.configuro工具、配置脚本infile.cfg等。此外还详细解释了这些工具如何帮助整合实时系统组件(RTSC)到应用程序中。
1、xs 与 XDCsript
The xs command is used to execute XDCscript programs. XDCscript is a general-purpose programming language based upon the ECMA-262 Edition 3 standard – popularly known as JavaScript 1.5.
2、xdc.tools.configuro
The xdc.tools.configuro tool processes configuration files and generates several files that must be integrated into the build of applications that use RTSC components.
Running the configuro command generates a subdirectory with the same name as your CFG file (for example, mycfg for the mycfg.cfg file). This subdirectory is in fact a RTSC package. The configuro command allows you to import RTSC content, in the form of reusable modules built using XDCtools, into your application.
3、infile.cfg
A user-supplied configuration script that names a set of XDC modules, and optionally changes their configuration settings.
4、compiler.opt
A file containing C compiler command-line flags. These flags must included on the compiler command line for any C source file that directly accesses the XDC content. The flags define the header file include paths, and machine-mode compiler flags to ensure object code compatibility between all included content.
5、linker.cmd
A file containing linker command-line flags. These flags must be included on the linker command line for the final link of the application. The flags list needed libraries and object files, and on some platforms define the embedded system memory map.
6、config.bld
The build model "startup" script; this script, located along the import path ".;$(XDCPATH);xdcroot;xdcroot/etc", configures the build model's modules so that common settings can be shared among multiple package build scripts. It is possible to override this behavior using the XDCBUILDCFG environment variable.
7、package.bld
The package's build script; this script, located in the package's working directory, specifies all of the physical files (libraries, executables, etc.) that are part of the package.
8、.xdcenv.mak
This file is a generated file that captures the environment setting that can affect the contents of the generated makefile; changes to this file trigger a re-build of the makefile.
9、XDCspec 与 XDCscript
XDCspec - Elements of the RTSC specification language
XDCscript - Elements of the RTSC meta-language
The xs command is used to execute XDCscript programs. XDCscript is a general-purpose programming language based upon the ECMA-262 Edition 3 standard – popularly known as JavaScript 1.5.
