| Subject: docs/scripts/gdb: add necessary make scripts_gdb step |
| |
| From: Jakob Koschel <jkl820.git@gmail.com> |
| |
| [ Upstream commit 6b219431037bf98c9efd49716aea9b68440477a3 ] |
| |
| In order to debug the kernel successfully with gdb you need to run |
| 'make scripts_gdb' nowadays. |
| |
| This was changed with the following commit: |
| |
| Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb |
| constants.py") |
| |
| In order to have a complete guide for beginners this remark |
| should be added to the offial documentation. |
