| 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 |
| |
| SYMBOL TABLE: |
| 0000000000000000 l d .text 0000000000000000 .text |
| 0000000000000000 l d .data 0000000000000000 .data |
