cppdbg attach issues #5287
Description
- OS and Version: Linux Mint 19.3 x64
- VS Code Version: 1.44.0
- C/C++ Extension Version: 0.27.0
Issue 1:
When attaching to a program using cppdbg with processId as ${command:pickProcess}, the command pick does not wait for the preLaunchTask initialization/finalization, processId command pick should start just after the preLaunchTask finalization.
Issue 2:
Not able to pass environment variables values to cppdbg when attaching to a program, but is possible when launching. Why? Let's say I have a PID stored inside an environment variable and I would like to use this variable for the attach processId property, how I would do that?
