How to install and use Eclipse CDT for CC programming. Eclipse is an open source Integrated Development Environment IDE supported by IBM. The mother site is www. Eclipse is popular for Java project development. It also supports CC, PHP, Python, Perl, and other web project developments via extensible plug ins. Eclipse is cross platform and runs under Windows, Linux and Mac OS. How to Install Eclipse CC Development Tool CDT 8. Eclipse 4. 2. 2 JunoStep 0 Install Min. GW GCC or Cygwin GCCTo use Eclipse for CC programming, you need a CC compiler. On Windows, you could install either Min. E 40 History Function Music. GW GCC or Cygwin GCC. Choose Min. GW if you are not sure, because Min. GW is lighter and easier to install, but having less features. Min. GW GCC Read How to Install Min. GW. Cygwin GCC Read How to Install Cygwin. Make sure that you select gcc, g, gdb, and make packages under the Devel Development category these packages are not part of the default installation. Step 1 Install Eclipse CC Development Tool CDTTwo ways to install CDT, depending on whether you have previously installed an Eclipse If you have already installed Eclipse for Java Developers or other Eclipse packages, you could install the CDT plug in as follows Launch Eclipse Help Install New Software In Work with field, pull down the drop down menu and select Kepler http download. Eclipse 4. 2 or helios for Eclipse 3. In Name box, expand Programming Language node Check CC Development Tools Next. Finish. If you have not install any Eclipse package, you could download Eclipse IDE for CC Developers from http www. Step 2 Configuration. You do NOT need to do any configuration, as long as the Cygwin or Min. GW binaries are included in the PATH environment variable. CDT searches the PATH to discover the CC compilers. Building and Installing ACE and Its Auxiliary Libraries and Services Synopsis The file explains how to build and install ACE, its Network Services, test suite and. How to Install Cygwin. Cygwin pronounced as SIGwin GNU Cygnus Windows. The mother site for Cygwin is www. According to the developers, Cygwin is. Are there any user friendly tools out there to crosscompile from Windows to LinuxWriting your First CC Program in Eclipse. C Program. Step 0 Launch Eclipse. Start Eclipse by running eclipse. Eclipse installed directory. Choose an appropriate directory for your workspace i. If the welcome screen shows up, close it by clicking the close button. Step 1 Create a new C Project. For each C application, you need to create a project to keep all the source codes, object files, executable files, and relevant resources. To create a new C project Choose File menu New Project. CC C project. The C Project dialog pops up. In Project name field, enter First. Project. In Project Types box, select Executable Empty Project. In Toolchains box, choose your compiler, e. Cygwin GCC or Min. GW GCC Next. The Select Configurations dialog appears. Select both Debug and Release Finish. Step 2 Write a Hello world C Program. In the Project Explorer leftmost panel Right click on First. Project or use the File menu New Source File. The New Source File dialog pops up. In Source file field, enter Hello. Click Finish. The source file Hello. Enter the following codes. Hello, world lt lt endl. If Unresolved Inclusion ErrorIf error unresolved inclusion appears next to include statement, the include paths for headers are not set properly. Select Project menu Properties CC General Paths and Symbols In Includes tab For Cygwin GCC Add the following directories to GNU C, where CYGWINHOME is your Cygwin installed directory. CYGWINHOMElibgcci. CYGWINHOMElibgcci. CYGWINHOMEusrincludeCYGWINHOMEusrincludew. Add the following directories to GNU C, where CYGWINHOME is your Cygwin installed directory. CYGWINHOMElibgcci. CYGWINHOMElibgcci. CYGWINHOMElibgcci. CYGWINHOMElibgcci. CYGWINHOMElibgcci. CYGWINHOMEusrincludeCYGWINHOMEusrincludew. For Min. GW GCC Add the following directories to GNU C, where MINGWHOME is your Min. GW installed directory. MINGWHOMElibgccmingw. MINGWHOMEincludeMINGWHOMElibgccmingw. Add the following directories to GNU C, where MINGWHOME is your Cygwin installed directory. MINGWHOMElibgccmingw. MINGWHOMElibgccmingw. MINGWHOMElibgccmingw. MINGWHOMElibgccmingw. MINGWHOMEincludeMINGWHOMElibgccmingw. NOTE To find the header paths, you can do a search on headers such as stdio. C and iostream for C under the Cygwin or Min. GW installed directory. Step 3 CompileBuild. Right click on the First. Project or use the Project menu choose Build Project to compile and link the program. Step 4 Run. To run the program, right click on the First. Project or anywhere on the source test. Run menu Run As Local CC Application If ask, choose Cygwins gdb debugger The output Hello, world appears on the Console panel. NOTE You need to create a new C project for EACH of your programming problems. This is messy for writing toy programsC Program. Follow the same steps as above. Create a C Project instead of C Project. Try the following Hello world program called Hello. Hello, worldn. C Program with Makefile. In the previous examples, we use so called managed make where Eclipse automatically generated a makefile to build the program. We can also choose to write our own makefile for complete control of the building process. Step 1 Create a C Makefile Project. From File menu New Project. CC C project In Project name, enter Hello. Cpp. Makefile In Project type, choose Makefile Project, Empty Project In Toolchains, choose Cygwin GCC or Min. GW GCC. Ignore the warning message. Step 2 Write a C Program. Right click on the project New Source File In Source file, enter Hello. Enter the following source codes. Hello, world lt lt endl. Step 3 Write a Makefile. Right click on the project New File In File name, enter makefile Enter the following codes. Take note that you need to use a Tab NOT Spaces for the indent. Hello. o Hello. exe. Hello. exe Hello. Hello. exe Hello. Hello. o Hello. cpp. Hello. cpp. Step 4 Build the Project. Right click on the project Build Project. Step 5 Run the Program. Right click on the project Run As Local CC Application. TODO Write a makefile to compile toy programs under one project. Read the Documentation. At a minimum, you SHOULD browse through Eclipses Workbench User Guide and CC Development User Guide accessible via the Eclipses Welcome page or Help menu. This will save you many agonizing hours trying to figure out how to do some things later. Debugging CC Programs in Eclipse CDTAble to use a graphics debugger to debug program is crucial in programming. It could save you countless of hours guessing on what went wrong. Step 0 Write a C Program. The following program computes and prints the factorial of n 12. The program, however, has a logical error and produce a wrong answer for n2. The Factorial of 2. The Factorial of lt lt n lt lt is lt lt factorial lt lt endl. The Factorial of 2. Let us use the graphic debugger to debug the program. Step 1 Set an Initial Breakpoint A breakpoint suspends program execution for you to examine the internal states e. Before starting the debugger, you need to set at least one breakpoint to suspend the execution inside the program. Set a breakpoint at main function by double clicking on the left margin of the line containing main. A blue circle appears in the left margin indicating a breakpoint is set at that line.
