Subject: | clang appends an extra string to Grub2 making it not work with MBR systems |
Date: | Tue, 3 Jan 2023 01:15:46 +0000 |
Using Gentoo with clang on a MBR system I have come across an extra string the content /lib/ld-linux.so.2
is being added to /usr/lib/grub/i386-pc/diskboot.img
and /usr/lib/grub/i386-pc/boot.img
taking it over 512 bytes meaning it can't be used on a MBR system.
You can use truncate
to remove the extra string then it will install and boot correctly but I am highlighting this here in hopes of a better fix.
Steps to reproduce in Gentoo:
Error:
Installing for i386-pc platform.
grub-install: error: diskboot.img size must be 512 bytes.
Workaround:
1. truncate -s 512 /usr/lib/grub/i386-pc/diskboot.img 2. truncate -s 512 /usr/lib/grub/i386-pc/boot.img 3. grub-install /dev/sda
I'm not really sure what files I can attach to help debugging this one but if you can think of any please ask for them.
