[yocto] How to avoid stripping libthread_db to enable gdb thread debugging?

[Hui Liu]

Hi,

I add gdb to my recipe, and found gdb can't enable thread debugging.

The warning from gdb is:

warning: Unable to find libthread_db matching inferior's thread library,
thread debugging will not be available

After some investigation, I found it is due to libthread_db is stripped:

nm lib/libthread_db.so.1
nm: lib/libthread_db.so.1: no symbols

Could you let me know how to avoid this?

Thanks,
Hui
