Problems building grub2 bootloader for Zephyr

[jaslob]

I want to use Zephyr as a User VM in ACRN. Therefore I followed the tutorials in https://projectacrn.github.io/latest/tutorials/using_zephyr_as_uos.html
I followed the zephyr getting started guide on my Ubuntu and when I want to build the grub2 bootloader image in step 2 I get the following message:

jas@ubuntu:~/zephyrproject/zephyr$ ./boards/x86/common/scripts/build_grub.sh x86_64

I'd be thankful for help.

Do you have autoconf and automake installed? IIRC, in Ubuntu, the packages are of the same names.

[jaslob]

Thanks. It took some time but it did finally work.

Thanks. It took some time but it did finally work.

hey @jaslob can you still run grub on x86 with Zephyr? somehow it does not work for us, can you share how it works for you?

What were the error messages?
