Question

I am using eclipse CDT for creating the projects. I am creating a workspace and have to create projects in sub directories

   + workspace
   |
   +--+ level 1 (folder)
   |  | 
   |  +-- project 1
   |  |
   |  +-- project 2
   |
   +--+ level 2 (folder )
   |  |
   |  +--+ level 3 (folder inside level 2)
   |     |
   |     +--- project 3

As per above diagram I have to create project 1 and 2 inside the folder called level1, similarly project 3 inside the folder level 3 ( level 3 folder is inside the folder level2 )

If i try to create the project it says “overlaps the location of another project”

Kindly give suggestions.

Answer 1

First of all, I have no experience with CDT, but met similar situation with JDT (Java Development Tooling), so my answer may help. In the following, the term <workspace> denotes the root directory of your workspace.

• Eclipse projects want to be created all the time directly in the workspace on top level.
• However, there is an option to select a different location for the project. It should be done like that:
  1. In the project creation dialog, enter the project name.
  2. Deselect the check box “Use default location”, and enter manually the directory <workspace>/level_1/project_1.
  3. Finish your dialog.
  4. Repeat that process with the following inputs:
     • <workspace>/level_1/project_2
     • <workspace>/level_2/level_3/project_3
  5. You should now have 3 projects in Eclipse.
  6. When you look at the file system (outside eclipse), you should see the directory structure you wanted to get.
• What is not possible to have projects inside other projects. So level_1, level_2 and level_3 are only directories, no projects. And they are not visible in eclipse. There are exceptions to that rule (e.g. the m2e plugin for Maven integration into Eclipse), but it has to be implemented by the plugins. I am not aware of a solution for CTS, but I don’t know CDT well.

Detailed instructions

The following was done in an Indigo installation (Eclipse 3.7) where CDT was added as feature (version 8.0.0).

1. Go to the “C/C++” perspective.
2. Select in the “Project Explorer” New > C-Project (should work for C++ as well).
3. Deselect the check box “Use default location”.
4. Paste in the Location text box: <workspace>/level_1/project_1.
5. Enter into the “Project name”: project_1.
6. Finish the dialog.
7. As a result, you have a directory structure <workspace>/level_1/project_1 and in the project explorer a project name project_1.
8. Repeat the step 2 to 5 with the directory <workspace>/level_1/project_2 and the project name project_2.

At the end, you have 2 projects named project_1 and project_2, which lay in the common directory level_1. I hope this is now sufficient to recreate it for you.
