Subject: [PATCH] grub module explicitly keeps symbole .module_license
|
|
While using oe-core toolchain to strip grub module 'all_video.mod',
|
it stripped symbol table:
|
|
---------------
|
root@localhost:~# objdump -t all_video.mod
|
|
all_video.mod: file format elf64-x86-64
|
|
SYMBOL TABLE:
|
no symbols
|
--------------
|
|
It caused grub to load module all_video failed.
|
--------------
|
grub> insmod all_video
|
error: no symbol table.
|
--------------
|
|
Tweak strip option to keep symbol .module_license could workaround
|
the issue.
|
--------------
|
root@localhost:~# objdump -t all_video.mod
|
|
all_video.mod: file format elf64-x86-64
|
|
