v4l2loopback installation problem

Recommended Posts

I have read other thread regarding v4l2loopback kernel module installation.

I got same problem like this message below

=========================================


------------------------------
Deleting module version: 0.10.0
completely from the DKMS tree.
------------------------------
Done.
Unpacking v4l2loopback-dkms (0.10.0-1) over (0.10.0-1) ...

dpkg: warning: version '3.4.113-sun8i
4.19.25' has bad syntax: invalid character in revision number
Building for 4.19.20-sunxi64
Module build for kernel 4.19.20-sunxi64 was skipped since the
kernel headers for this kernel does not seem to be installed.
 

===================================

I am usng Nano PI neo2 with armbian 4.19.20.

When I install the kernel-headers using armbian-config, the version of kernel-headers installed is 4.19.25.

Either the kernel source I have installed using armbian-config is 4.19.25.

 

I just guess the version mistach doesn't make me succeed build of v4l2loopback.

But I can't figure out what to do with this error.

 

Please give me some comment.

I have installed correct headers.

And tried to build v4l2loopback again and get below message failed.

What's wrong with me ?
