Are there plans for a Linux kernel 4.x RealPort driver?

I’m running the following version of Ubuntu (“lsb_release -a” output):

Distributor ID: Ubuntu
Description: Ubuntu 15.10
Release: 15.10
Codename: wily

Which is running the following kernel version (“uname -r” output):


I would like to install and use the Linux RealPort driver to use a Digi PortServer TS 16 MEI. Following the directions here:

I attempted to install the driver (40002086_W.src.rpm) without success (compile time error). Moving backwards, I downloaded the source tarball ( 81000137_W.tgz ), extracted it, and then attempted to follow the instructions in release_notes.txt without success.

And yes, I am aware that THIS IS NOT SUPPORTED according to the release notes (release notes only promise support for the 3.x.x kernel).

In case you’re interested, the errors during build (“make all”) look similar to the following:

dgrp_net_ops.c:502:31: error: ‘TTY_CLOSING’ undeclared (first use in this function)

Is there a known workaround for this, or is there an expected time when the 4.x kernel will be supported for the RealPort driver?

Can you try the following release candidate and post your results?

I get further, but still no joy. Since there’s an 8K character max here, but the log is 37K in length, I can’t post a complete log. Here’s the beginning:

With the help of other responders, and after finally getting back to working on this, I have a solution for Ubuntu 14.04 LTS (clean install). I post this in case someone else has the same need. The normal disclaimers apply.
