After Creating a New Project, you can add source files, then build and run your completed project. Follow these steps to add a hello.c source file to the helloworld project.
From the Eclipse* File
menu, select New > File.
Enter hello.c in the File
name text box of the New File
dialog. Click Finish to add the
file to the helloworld project.
Your Eclipse Preference settings in Window
> Preferences > Workbench
let you specify Perform build automatically
on resource modification. If this preference is checked, Eclipse/CDT
will attempt a build when hello.c is created.
Since hello.c does not yet include code, errors
are indicated in the Tasks view
and C-Build view near the bottom
of the screen. This is expected behavior, not a true error. Select Window > Show
View > C/C++ Projects
to view the project files.
In the Editor
view, add your code for hello.c. If you close
hello.c in the Editor
view, you can open it by doulble-clicking on hello.c
in the Navigator view.
When your code is complete, save your file using File > Save, then proceed to Building a Project.
