Type: Debugger

Describe the bug

• OS and Version:Ubuntu 18.04.4
• VS Code Version: 1.43.2
• C/C++ Extension Version: 0.27.0
• Other extensions you installed (and if the issue persists after disabling them): Python and LiveShare, issue persistts after disabling the extensions
• A clear and concise description of what the bug is.

Please include a code sample and launch.json configuration.
`
launch.json.txt

`
Steps to Reproduce:

1. Install C/C++ extension ms-vscode.cpptools
2. Start debugging
3. Select environment: C++(GDB/LLDB)
4. Select gcc run and debug active file

A launch.json file is created but no tasks.json. So it does not compile before starting the debugger. I tried to do it by hand by going to Menu -> Terminal -> Configure tasks -> Create tasks.json file from template I do not have such option for creating tasks.json for 'gcc build active file'

Additional context
If applicable, please include logging by adding "logging": { "engineLogging": true, "trace": true, "traceResponse": true } in your launch.json
Add any other context about the problem here including log or error messages in your Debug Console or Output windows.
