[wbolster]

Hi,

I also tried to install the driver with the 4.7 kernel :

And in the make.log, I found the following traces :

Also fails in Gentoo on 4.7.0 with DRM library function errors. I'll second that the DRM libraries changed in 4.7.0

[rainerklier]

i fixed it myself by changing the code from the archive evdi-1.1.62-src.tar.gz.
i unpacked it, and changed it the following way:
in evdi_main.c change drm_connector_unplug_all() to drm_connector_unregister_all().
in evdi_fb.c, evdi_cursor.c and evdi_gem.c change all calls of drm_gem_object_lookup(dev, file, cmd->handles[0]) to drm_gem_object_lookup(file, cmd->handles[0]).
then i recreated the archive evdi-1.1.62-src.tar.gz with the changed files and ran the install script.

sorry that i have no patch file which automatically does all the above.

[displaylink-mlukaszek]

The module code have been adjusted to kernels up to 4.7 - closing.

[philippe-levan]

Thanks a lot !

[fdbozzo]

Hi, I've downloaded the Ubuntu script from http://www.displaylink.com/downloads/ubuntu and does not work with 4.7 kernel. (I'm using Ubuntu 16.04)
I can see that this is fixed now in development, but I don't know what to do with this c++ code. I've tryied with sudo make all, but throws errors (file libdrm/drm.h not found) and I don't know what to do now.
Can somebody help me with this?

Thanks, and sorry for posting it here, but I don't know where to ask, and the README does not explain how to compile or the pre-requisites

Edit:
As mentioned here (#6) I've installed libdrm-devel and now I can compile with sudo make all and sudo make clean without errors.
So now what I need to do with use it? I have the DELL D3100 Dock Station. Thanks.-

Edit 2:
Ok, found it, I did this:

1. copy "modules" contents into /usr/src/evdi-1.1.66 (invented "future" version)
2. compile with sudo dkms install -m evdi/1.1.66 --kernelsourcedir /usr/src/linux-headers-4.7.1-040701-generic
3. Reboot
4. sudo modprobe evdi
5. Confirmed loaded module with lsmod | grep evdi

Now I'm looking how to configure the HDMI attached monitor, which shows nothing
