I am trying to learn more about operating system and am following this tutorial: https://youtu.be/ZiHtuBnVrx4?list=PLHh55M_Kq4OApWScZyPl5HhgsTJS9MZ6M. Everything was going smoothly until the point where I had to use grub-mkresuce to create an iso image to use with a virtual box. I am getting an error saying "your xorriso doesnt support '--grub2-boot-info'. Some features are disabled. Please use xorriso 1.2.9 or later.."
I am left confused and without an iso image. I have looked online for a solution but failed to find any. Any help will be greatly appreciated.
if your operating system does not offer a package "xorriso" or "libisoburn", or if they are older than version 1.2.9 (1.3.0 was released in 2013), then download and compile GNU xorriso. (MS-Windows users may need Cygwin to get the necessary compiler and linker tools.)
cd ...some.work.directory...
wget https://www.gnu.org/software/xorriso/xorriso-1.5.0.tar.gz
tar xzf xorriso-1.5.0.tar.gz
cd xorriso-1.5.0
./configure && make
Check whether the result is willing to work:
xorriso/xorriso
which should say
GNU xorriso 1.5.0 : RockRidge filesystem manipulator, libburnia project.
usage : xorriso/xorriso [commands]
More is told by command -help
You do not need to install it. Rather obtain its absolute address:
ls $(pwd)/xorriso/xorriso
and use it with the grub-mkrescue option "--xorriso=":
grub-mkrescue --xorriso=...absolute.address.of.xorriso...
Have a nice day :)
