Follow Analog Devices' What is libiio? wiki page, in order to build libiio for Debian-flavoured GNU/Linux distributions.

For CentOs you're able to get the required dependencies with the command:

$ sudo yum install libxml2 libxml2-devel libaio-devel libusbx-devel avahi-devel

then you can fetch the source, build and install

$ git clone https://github.com/analogdevicesinc/libiio.git
$ cd libiio
$ cmake ./
$ make all
$ sudo make install

libad9361-iio

Just fetch the source, build and install

$ git clone https://github.com/analogdevicesinc/libad9361-iio.git
$ cd libad9361-iio
$ cmake ./
$ make all
$ sudo make install

Troubleshooting

• if during cmaking libiio, you got: Check size of struct usb_functionfs_descs_head_v2 - failed, use the following commands to fix it, being able to support usb backend.

$ wget https://raw.githubusercontent.com/torvalds/linux/master/include/uapi/linux/usb/functionfs.h
$ sudo mv functionfs.h /usr/include/linux/usb/functionfs.h

• if having a library linking error when executing the device, adding these lines to the ~/.bashrc file might do the trick:

if [[ $LD_LIBRARY_PATH != *"/usr/lib64"* ]]; then
	LD_LIBRARY_PATH=/usr/lib64:${LD_LIBRARY_PATH}
fi
if [[ $LD_LIBRARY_PATH != *"/usr/local/lib"* ]]; then
	LD_LIBRARY_PATH=/usr/local/lib:${LD_LIBRARY_PATH}
fi
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}
