---------------------------------------------------
Build Date: 2021-May-21 1607 EDT
Ghidra Version: 10.0-BETA
Java Home: C:\Program Files\AdoptOpenJDK\jdk-11.0.9.101-hotspot
JVM Version: AdoptOpenJDK 11.0.9.1
OS: Windows 10 10.0 amd64
Workstation: Gabe-R-Laptop

To Reproduce
Steps to reproduce the behavior:

  1. Load binary file into Ghidra for Analysis
  2. Use CodeBrowser to Analyze File
  3. Open Analyzed file in Debugger
  4. Add debugger target using the Create a new connection to an debugging agent button
  5. Set debugger to 'IN-VM GNU gdb local debugger`
  6. Set GDB launch command to arm-none-eabi-gdb.exe (assuming this on on PATH)
  7. Press Connect

Expected behavior
Debugger is launched successfully.

Environment (please complete the following information):

  • OS: Windows 10 21H2
  • Java Version: 11.0.9.1
  • Ghidra Version: 10.0BETA
  • Ghidra Origin: ghidra-sre.org

Additional context

The stack trace mentions Linux at some points. Perhaps the Linux code instead of Windows code is being called?

I was following the instructions on https://wrongbaud.github.io/posts/ghidra-debugger/

@marsfan We're aware of this issue, and, if you're interested, maybe scan the Discussion under"GNU gdb local agent via GADP/TCP". The issue basically comes down to the lack of a Pty equivalent on Windows. @DrChat suggested using ConPTY - we haven't had a chance to look into that. The current viable solution is to use the SSH client rather than the "local" clients. Requires installing SSH on your box, and again details in that Discussion (a ways down).
