Re: [cdt-dev] 'Failed to execute MI command: -exec-run' error when tryin

[Evan Aad <oddeveneven@xxxxxxxxx>]

I've now managed to debug the Emacs source code with gdb using Emacs itself as the IDE. However, I prefer to use Eclipse, and would appreciate help to get it done.

Additionally, I've managed to solve the error message I reported about above, however now I'm getting another one:

---

'Launching emacs-26.0.50.1' has encountered a problem.

Error in final launch sequence

Failed to execute MI command:
source /Users/evanaad/emacs/src/.gdbinit
Error message from debugger back end:
/Users/evanaad/emacs/src/.gdbinit:19: Error in sourced command file:\nNo symbol table is loaded.  Use the "file" command.
/Users/evanaad/emacs/src/.gdbinit:19: Error in sourced command file:\nNo symbol table is loaded.  Use the "file" command.

I initially got a similar message with Emacs as the IDE. The way I was able to resolve it there was to set gdb's current directory using

(gdb) cd ~/evanaad/emacs/src

And also to set gdb's executable file to 'bootstrap-emacs' thus:

(gdb) file bootstrap-emacs

No, I can't debug even a simple Hello World application. How aggravating!

Thanks for answering.

Hi,

Does debugging a simple Hello World application work for you?

If not, I suspect it is because GDB 7.12 does not work on MacOS
Sierra. I don't have access to such a machine, but have a look at
https://stackoverflow.com/a/40123809/2796832 as a starting point
perhaps?
