After you get past the installation issue using Georg's suggestion to uncheck the 'group items' box, here is the recommended procedure for migrating your cdt5 projects in your Ganymede workspace to your new Helios cdt7 workspace.
- Start your new Eclipse/cdt7 instance.
- Use File > Import to start the process.
- In the UI that opens, select General > Existing Projects into Workspace and click Next.
- In the Select root directory box, browse to your Eclipse/cdt5 Ganymede workspace directory where yourcurrent projects reside. Then select the projects you want to import. Also, check the box for 'Copy projects into workspace'. Click Finish.
You should see the new copy of the projects with your 11.1 configurations in your new workspace now. If you have the -V option enabled in your projects, you should see they still build with the 11.1 compiler from the output in the Console view.
To create new configurations that build with the 12.1 compiler, use our 'Update Projects' tool from the Intel Tools menu (also accessible from the context menu).
- Use Intel Tools > Update Project > Update to the Latest Intel C++ Compiler.
This will open a UI that shows you the configurations that can be updated. In the UI, you can select which configurations you want to update, choose to keep or delete the current configuration, and change the name of the new configuration if you don't like the default name. By default, the tool does not delete the original configuration. The tool also copies your options settings to the new configurations for options that are available in both versions of the compiler. If it cannot keep an option in the new config, it will be reported in a log file so you can review it.
As an example, suppose you had a project XYZ that has a Debug and Release configuration, each of which builds with the 11.1 tool chain. After you use the project update tool, with all it's defaults, you would have the current Debug and Release configs which still build with 11.1, plus two new configs named Debug_i12.1 and Release_i12.1 both of which build with 12.1.
Note, if it is of interest to you, you can also use the Update Project tool to create configs that build with GCC.
There is some step-by-step help on using the update tool. Visit Help > Cheat Sheets > Intel C++ Integration > Updating Projects.
The user manual also has information on the tool. Visit Help > Help Contents > Intel C++ Compiler XE 12.1 User and Reference Guide > Getting Started > Using Eclipse > Updating a Project.
Hope this is helpful to you...Bill
