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

Question

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):

4.2.0-25-generic

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

http://knowledge.digi.com/articles/Knowledge_Base_Article/HOW-TO-Install-the-RealPort-Driver-in-Ubuntu-Linux

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?

Answer 1

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:

Your log shows the file was written in the rpmbuild path:

Try:

sudo alien -d --scripts /home/myusername/rpmbuild/RPMS/x86_64/dgrp-1.9-36.x86_64.rpm

Answer 2

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.

[Make temp directory and change directory to it]
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install openssh-server
wget ftp://ftp1.digi.com/support/beta/linux/dgrp/40002086_X6P.src.rpm
sudo sh
apt-get update && apt-get install -y rpm libncurses-dev alien
script
rpmbuild --rebuild 40002086_X6P.src.rpm
cd ~/rpmbuild/RPMS/x86_64
alien -d --scripts dgrp-1.9-36.x86_64.rpm
dpkg -i dgrp_1.9-37_amd64.deb
sudo update-rc.d dgrp_daemon defaults
dgrp_cfg_node init g 10.31.69.58 32 [replace IP address with your IP address and 32 with the number of ports you need]
reboot
