CDT projects

Before you can work in the CDT, you must create a project to store your source code, makefiles, binaries, and related files. C/C++ projects are displayed in the C/C++ Projects view.

Tip: Nested projects are not supported. Each project must be organized as a discrete entity. Project dependencies are supported by allowing a project to reference other projects that reside in your workspace. For more information, see Selecting referenced projects.

For more information about projects and where they are stored, see:

• Workbench User Guide > Tasks > Resources
• Workbench User Guide > Tasks > Running Eclipse

Project types

You can create a standard make C or C++ project or a managed make C or C++ project.

Standard make C or C++ project

You need to create a makefile in order to build your project or use an existing makefile.

Managed make C or C++ project

A managed make project generates the makefiles for you automatically. These files are required for your managed make projects to build successfully.

Project conversion

You can convert projects from C to C++ (or from C++ to C). If, for example, your requirements change and you must convert an existing C project to C++, you can do this without recreating the project. The CDT converts your project files and resolves any source control issues.

A few notes about projects

• When you create a file within a project, a record (local history) of every change is created. For more information about local history, see Workbench User Guide > Reference > User interface information > Development environment > Local history.
• Spaces in projects and filenames can cause problems with some tools, such as the make utility or the compiler.
• Be careful when you use only case to distinguish files and projects. UNIX-based operating system file names are case sensitive, but Windows filenames are not. Therefore, Hello.c and hello.c are separate files in UNIX but overwrite each other in Windows.

For more information about projects, see Workbench User Guide > Concepts > Workbench > Resources.
