Error running #62

Hello.

I installed all in ubuntu 18.04 and confirmed that VC4C is working. However, while creating a cl::Buffer I get this error message:

[VC4CL] test_cl.o: ioctl_set_msg failed: -1
[VC4CL] Error in mbox_propertie: Inappropriate ioctl for device

Any idea what this may be? Thanks in advance.

Did you install Raspbian or a "vanilla" Ubuntu?

OSes other than Raspbian do not provide the mailbox driver and the accompanying character device to communicate with the firmware.

I installed Ubuntu because I need to work on it...

Is it possible to install those things in Ubuntu?

You will need to provide the Raspberry PI userland and firmware and also probably the correct kernel module, see here and here.
