Hi,

Please make sure all VirtFS dependencies(libattr1-dev and libcap-dev) installed in your environment.
You can install them by
sudo apt-get install libattr1-dev libcap-dev

And have a try again. Thanks a lot!

I follow the command and appear this

libattr1-dev is already the newest version.
libcap-dev is already the newest version.

But i got the same problem.
Have any suggestion? Thanks.

Hi @allenlaitw ,

Can you check if there is '#define CONFIG_VIRTFS 1" in the generated vp/libs/qbox.build/config-host.h? If not, then it means that the virtfs is not built with QEMU.

The QEMU build flow is supposed to check if cap and attr is available and enable this option. If you are sure they are all available, can you try remove the vp/libs/qbox.build and re-build the simulator. You can also use our docker image which includes the development environment and a prebuilt binary.
