Based on Eclipse Embedded Development Platform Integration Solution BalanceSli writes' Eclipse embedded development integration scheme Author: balancesli email: balancesli@thizlinux.com.cn Objective: To provide an efficient development platform for the development of embedded Linux products. Users who are ultimately provided by the product provide the greatest support on the "Development Support Platform". Difficulties: Host end operating system selection Linux, Windows, Cygwin development platform, 2.1 Whether to support CVS version control 2.2 Whether the interface interaction is friendly (graphical editing interface) 2.3 Development Kit can support multiple target machine systems (x86 , MIPS, POWERPC, ARM, STRONGARM, XSCAL, etc.) 2.4 Whether the platform provides (C / C ), compiled, debugging, cross-compiled debugging environment, the size of the target code generation and its implementation efficiency. 2.5. Development platform Unrelated support solution: (Solve technology route and specific scheme) is determined by the above Eclipse open work platform. Due to the openness of the Eclipse IDE platform and its friendly interface, it can be rooted in plug-ins. The Eclipse is used as the software development platform. Take advantage of Eclipse's CVS version control interface provides CVS-based version control and resource allocation management. Program management development. (CDT itself as an Eclipse platform plugin, it provides a very efficient editing environment, can be used as a RAD tool for embedded development, greatly improves development efficiency) NOTE: CDT development environment is best to use Linux System Platform 4. CDT Depending on Three GNU Tools Chains: GCC, GDB, and Make or related tools that support cross-compilation. CDT supports automatically generating makefile and standard Makefile Note: Analysis of the CDT source code, whether you can complete some specific needs through its internal transformation. Difficulty is the familiarity and analysis of Java code. Final CDT solution model: UI (user interface) Makefile Generator (Makefile Builder) It generates the corresponding Makefile CDT ELF PARSER (Binary Resolver) Tool Integrator (GNU Tool Chain Integrator) Tool Chain Configuration Management Model (BUILD Model Schema) Managed Build Model Schema Through the above model, you can customize the integration of the 7-type PDA development platform. Note that after installing the CDT plug-in, Welcome.xml already has a significant elaboration The CDT Project Provides A Set of Plugins That Implement A C / C IDE. It adds a C / C Perspective to the Eclipse Workbench that supports C / C development with a number of views, wizards, a powerful editor, and a debugger. The CDT is designed to provide an extensible architecture, that will provide support For Integration Of Tools Provided by Independnt Software Vendors. A very flexible system. .
Build Model Grammar Elements Relation Schema: ManagedBuildInfo: ManagedBuildInfo: By the above model: It can fully infer the design idea of the CDT Toolchain management. Design IDEA is very important! Guess these toolchain configuration management information in the CDT is finally handed over to MakefileGenerator Generate the corresponding Makefile file, then compile it by the Make tool. Here we can transition to org.eclipse.cdt.make.core org.eclipse.cdt.make.ui These two packages are like and manipulating the Make tool The class model in Source and its corresponding class is as follows: Class TARGET CLASS CONFIGURE CLASS TOOL Class Toolreference Class Option Class OptionCategory >>>>>>>>>> Code Source Code: Class Definition in C (Class ) Inner method.

} Most of the interactive interfaces that are configured with Toolchain management are calling SWT, JFACE to implement the build model of specific Toolchain to CDT, which can customize the DOM node model of the PLUGIN.XML configuration file. There is a very picture of whether the overall design model in each plugin can be launched by the PLUGIN.XML configuration file corresponding to the package in the process of reading the source code? Package analysis: ??? Class MakefileCodescanner makefile code scanner After Read Source, a Makefile file contains some rules, macro definition, and then comment they are all collectively referred to as an indicator (Directive).
