I'm trying to build IIO-Oscilloscope from the iio-oscilloscope main branch on Ubuntu 20.04 LTS from the instructions provided here. I was having an issue with the gtk version while using cmake. But I solved that using the answers provided here. I have also built libiio from the libiio github main branch. Now while trying to run the Makefile for IIO-Oscilloscope I am getting the following error
Can someone take a look into this issue?
