Hi, trying to install or compile v4l2loopback.

 

I fail with missing header message. I have tried armbian-config and apt-get for the headers but all fails.

I have tried stable and dev.

 

Anyone know how to do this?

Buildning gives me this:

This is what I get when trying to install with apt-get:

I have tried stable and dev.

Switch to automated nightly builds and try default and next kernel, skip DEV. They all have matching headers and repeat the process.

Should I do that through armbian-config? Install headers just blink and change kernel only gives me one option that says failed, aborting. Maybe I should reinstall, might have messed up with my attempts.

Ok, so I have re flashed my card. Went with:

Armbian Stretch
mainline kernel 4.14.y

 

Enabled nightly builds and installed headers. So far so good. Updated.

 

orangepiplus2e:~/v4l2loopback$ make VERBOSE=1
Building v4l2-loopback driver...
make -C /lib/modules/`uname -r`/build M=/home/aaa/v4l2loopback modules

  MODPOST 1 modules

Makefile:42: recipe for target 'v4l2loopback.ko' failed
make: *** [v4l2loopback.ko] Error 2

 

So I wanted to try and switch default and next kernel as suggested.

 

However; the only option is to switch from next to dev?  This is in "Switch", should I use "Default, install desktop ..." instead?

Try:

cd /usr/src/linux-headers-4.17.5-sunxi

make scripts

 

and repeat building.

after:

sudo apt-get install bison libbison-dev flex libfl-dev

 

make scripts

Sucsess!

Thank you!!

Great!

 

One more thing. Since you switched to beta.armbian.com repository and since this kernel is getting daily updates ... freeze kernel updates. Possible in armbian-config menu ... or manually (apr-mark).

Yes, thanks!

 

Did I just mess up or are there no uninstallable headers for the stable version?
