My installation of Indigo has ‘Launch Group’ in the debug configuration window. My colleague’s does not. What do I have installed that he does not?
To see them, I click on the arrow next to the bug icon, I select ‘Debug Configurations…’, and I see a green arrow labelled ‘Launch Group’ in the list of top-level items on the left.
I understand now. Based on this page, it looks like it’s contributed by the CDT feature set (as of version 6.0). Check that your colleague has CDT installed.
