Installing libad9361 from source

Can you delete teh build folder and try again ?

What are the commands that you are running ?

Hello, I am facing the same problem as well. I have installed libiio according to the document https://wiki.analog.com/resources/tools-software/linux-software/libiio

When I try to install libad9361 from the source, I am geeting the following error. I have tried building several times but struck with the same error

It looks like libiio was not installed correctly. I need all the commands used to build libiio and libad9361 including cd, mkdir, make, etc ..

I think there is a problem on out part .. libiio main branch is not compatible with libad9361. Remove libiio build folder and the files that were installed by the previous libiio installation

sudo rm -rf /usr/lib/x86_64-linux-gnu/pkgconfig/libiio.pc /usr/lib/x86_64-linux-gnu/libiio.so.1.0 /usr/lib/x86_64-linux-gnu/libiio.so.1 /usr/lib/x86_64-linux-gnu/libiio.so  /usr/include/iio/

Careful when running the rm -rf command as mistyping can cause problems :) 

Then try installing libiio like this:

git clone https://github.com/analogdevicesinc/libiio

cd libiio

git checkout v0.25

mkdir build && cd build && cmake ../ && make && sudo make install

and continue installing libad9361

Hello！I found that this problem is not linked to the header file of the libiio library. It can be solved by referring to the following link.

github.com/.../108

Or ,you can use Ubuntu22.04, install it with "sudo apt install libad9361-dev"
