meson setup fails with 'Dependency "glib-2.0" not found'

[geerlingguy]

Trying this on an Ubuntu 24.04 install on AmpereOne, I'm getting the following message when running the build script:

Run-time dependency glib-2.0 found: NO (tried pkgconfig)

../meson.build:926:10: ERROR: Dependency "glib-2.0" not found, tried pkgconfig

A full log can be found at /home/ubuntu/qemu-coremark/qemu-9.1.0/build/meson-logs/meson-log.txt

ERROR: meson setup failed

From that log...

What does grep ID_LIKE /etc/os-release show on your system?

[geerlingguy]

@bexcran

ubuntu@ubuntu:~$ grep ID_LIKE /etc/os-release
ID_LIKE=debian

[geerlingguy]

@bexcran - After manually installing libglib-2.0-dev, it seems like the build is progressing further.

Hmm... now the launch script is showing VM 0 failed to start:

Running QEMU VMs...............................................
Checking if VMs successfully started.
QEMU VM 0 failed to start. See /tmp/qemu0.log for details.

[geerlingguy]

If I try running the script with sudo it then shows me a bunch of permission denied warnings from subprocesses.

I'm only in the following groups:

ubuntu@ubuntu:~/qemu-coremark$ groups
ubuntu adm cdrom sudo dip plugdev lxd ollama

Do I need to ad myself to any more groups to make this work?

[bexcran]

Try adding yourself to the kvm group.
You can check if that's the correct group by doing ls -l /dev/kvm and looking at the group.

[geerlingguy]

Hooray!

sudo usermod -a -G kvm ubuntu

Then logout / login, and now ./launch_qemu.sh seems to be working.

@geerlingguy now try it on x86 😁
