Re: GDB + SIM broken with macOS sierra

I also tried to use lldb for a few days, and decided that gdb setup is still 
worth the
trouble.

I have this running. But it’s not great.

You need gdb 7.12.1 (you can get that with brew).
Codesign your gdb; https://sourceware.org/gdb/wiki/BuildingOnDarwin 

And then I also had to make gdb owned by root with SUID bit set (Peter didn’t
need to, so your YMMV).
Add the following to your .gdbinit:
  set startup-with-shell off

And that should do it. It is not without it’s it’s woes. Every process I run
under gdb ends up being a zombie. It’s like the walking dead season 1
on my laptop. However, I can do ‘newt run’ with my targets.

Hope this helps,
M

GDB + SIM broken with macOS sierra

[Sterling Hughes]

I’m wondering if anyone else has seen this / worked around it?

I can run SIM directly from command line, or under LLDB, but GBD seems 
to be broken?
