4 years ago I haven't used this code in quite a while, but I see no reason it shouldn't still work.
Try adding:
#include <stdint.h>
To the very top of evdi-vnc.c. If that fixes this then I'll update the repo.

4 years ago I didn't run as sudo, as I couldn't boot any more after I tried to compile
To the commands above I use, I also added, adb command to open bVNC on the tablet, still checking how to get right profile launched as well. If evdi-vnc would work, that would be great, because you are supposed to be able to add upto to 5 displays
` adb reverse tcp:5900 tcp:5900;
adb shell monkey -p com.iiordanov.freebVNC -c android.intent.category.LAUNCHER 1;
xrandr --addmode HDMI-A-0 1920x1080_60.00;
xrandr --output HDMI-A-0 --mode 1920x1080_60.00 --right-of DVI;
x11vnc -rfbauth ~/.vnc/passwd -clip 1920x1080+1920+0; ` this works but then the HDMI is blocked.

4 years ago systemctl start displaylink sudo modprobe evdi ahead of make, doesn't change anything

4 years ago If your code could get to work again and merged with this project, that would be awesome
https://github.com/kbumsik/VirtScreen
Virtscreen uses intel virtual screen which doesn't work with amd or nvdia. I try to get the adb commands added as well,
Hello, is this still active?
Just found it, tried to compile it. The instructions are unclear,
if you donwload the ZIP, it doesn't include the evdi folder. That need to be downloades separatly and put into the evdi folder.
compiling exit with failure:

Also adding adb command: adb reverse tcp:5900 tcp:5900
should increase the speed, as you can use USB connection.
and with the adb command "adb shell wm size"
theoretically mixing this should make possible to get ta plug an play solution.
ATM I use the following commands to get the screen extended to my android tablet.
adb reverse tcp:5900 tcp:5900 xrandr --newmode "1920x1080_60.00" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync xrandr --addmode HDMI-A-0 1920x1080_60.00 xrandr --output HDMI-A-0 --mode 1920x1080_60.00 --right-of DVI x11vnc -rfbauth ~/.vnc/passwd -clip 1920x1080+1920+0
But this takes away the monitor connection and I would extend the screen even more, I thought about evdi, can't get it running yet.
