evdi: DKMS build fails to build evdi module with kernel 5.4.0-42 Ubuntu 18.04

Initially please make sure the problem hasn’t been already addressed:

Are you using the latest driver? (https://www.displaylink.com/downloads/ubuntu)
Are you using the latest EVDI version? (https://github.com/DisplayLink/evdi/releases)
If you are using a DisplayLink device, have you checked ‘troubleshooting’ on DisplayLink’s website? (https://support.displaylink.com/knowledgebase/topics/103927-troubleshooting-ubuntu)
Is this issue related to evdi/kernel? (if it is rather connected to DisplayLinkManager please take a look at support https://support.displaylink.com or forum https://www.displaylink.org/forum/)

Some information for baseline would help a lot:

Linux distribution and its version : Ubuntu 18.04 x86_64
Linux kernel version : 5.4.0-42
Xorg version (if used) : xserver-xorg-core-hwe-18.04 2:1.20.8-2ubuntu2.2~18.04.1
Desktop environment in use : Gnome

I was successfully using displaylink with kernel 5.3.0-62. At some point, my kernel got updated to 5.4.0-42 and the multiple displays connected to a Targus adapter stopped working.

It seems dkms fails to build the evdi module for the kernel 5.4.0-42 as given in the /var/lib/dkms/evdi/5.2.14/build/make.log file. At the very start, my distro was missing flex and bison which I installed; Then it complained about a missing /usr/src/linux-headers-5.4.0-42-generic/tools/build/Build.include . I applied the Makefile modification in here but that did not fix the issue, dkms build was still complaining about a missing Build.include. Then I simply “touch /usr/src/linux-headers-5.4.0-42-generic/tools/build/Build.include”. Then the compilation stopped with :

make[4]: *** No rule to make target '../../scripts/utilities.mak'.  Stop.
Makefile:54: recipe for target '/usr/src/linux-headers-5.4.0-42-generic/tools/objtool/libsubcmd.a' failed
make[3]: *** [/usr/src/linux-headers-5.4.0-42-generic/tools/objtool/libsubcmd.a] Error 2

For now, I enforce grub to start with kernel 5.3.0-62 with which evdi is working. The full make.log file is given below :

I had the same problem with the 5.4.0-80-generic kernel.

My solution was:

Download and extract the displaylink driver from https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu
sudo displaylink-installer uninstall
Reboot in a tty without any X-server running
sudo dkms remove evdi/5.2.14 --all -q
sudo apt install --reinstall linux-headers-$(uname -r)
sudo displaylink-driver-5.4.0-55.153.run
reboot and login

I resolve with this: https://github.com/AdnanHodzic/displaylink-debian

Not sure if I know more about dkm than anyone here 😉

DisplayLinkManager is shipped now with evdi sources snapshot. module is build with dkms install ${PATH_TO_EVDI}/module and library with just a make. (just for some clarity maybe how it’s working)

So, after a while (sorry, been on late holidays 😉 )

Have everyone somehow resolved the problem or do we see still some instance of this issue?

Hi, I tried this morning on 5.4.0-47 with a fresh git clone and it worked successfully (see below).

Can it be related to the way dkms is building the module ? Interestingly, the relocs_32 error raised by @cement-head reminds me a kernel module compilation error I got recently (see here that I solved by replacing the compilation of the module from “sudo make” into “sudo su; make”

Successfull compilation from the git repo on a 5.4.0-47

@cement-head /bin/sh: 1: flex: not found flex is missing. Is it installed? sudo apt install flex on Ubuntu. But this seems to be something different than @bbros-dev sees.
