Anbox, cannot access '/dev/binder'

[aliquo93]

Hi, I have the same problem described in this thread on Super User:

https://superuser.com/questions/159...dev-binder-no-such-file-or-directory-in-anbox

Anyway, when I run INSTALL.sh as suggested by Yadu, I get the following:

Kernel preparation unnecessary for this kernel.  Skipping...
    
    Building module:
    cleaning build area...
    make -j4 KERNELRELEASE=5.8.0-38-generic all KERNEL_SRC=/lib/modules/5.8.0-38-generic/build....(bad exit status: 2)

Any help? I hope that here I can find someone who can help, because on Super User no one cared about my problem. I'm on Kubuntu 20.10.

I would do as it says: "Consult /var/lib/dkms/anbox-binder/1/build/make.log for more information." And it seems it can't find the binary package anbox-binder, I would start by looking at those.

Hi, thanks for your reply. Here's the content of '/var/lib/dkms/anbox-binder/1/build/make.log':

What distribution are you running?

Kubuntu 20.10

I was able to build it without any problems. What happens when you run these commands from the command-line seperately from that anbox-modules git directory, can you share the output?

sudo dkms install anbox-ashmem/1
sudo dkms install anbox-binder/1

Looks like it's a bug with kernel 5.8.x:

Can you share the output of the following:

That means the modules you install are already loaded so you should be good to go according to what is mentioned in the github issue, if not you will have to wait until they fix the bug.
