g++ error, several undefined reference to `xrt::

[EnzoRafinesque]

Hi,
I'm trying to follow the Vitis Getting Started tutorial and I encounter an issue in the part 4 : Build and Run the Data Center application,

I'm working on Ubuntu 20.04 and I've installed xrt for Vitis 2022.1 / Alveo U200 board following this : https://www.xilinx.com/products/boards-and-kits/alveo/u200.html#gettingStarted

The issue is on the command : g++ -Wall -g -std=c++17 ../../src/host.cpp -o app.exe -I${XILINX_XRT}/include/ -L${XILINX_XRT}/lib/ -lOpenCL -lpthread -lrt -lstdc++

and it return the following error :

I've searched on issues and other forums but I didn't found anything about that issue, if someone have an idea that will be helpful, thank you.

Best Regards,

Enzo.

From 2020.2 release XRT provides a new XRT API set in C, C++, and Python flavor.

To use the native XRT APIs, the host application must link with the xrt_coreutil library. Compiling host code with XRT native C++ API requires C++ standard with -std=c++17 (or newer).

add -lxrt_coreutil in the command to fix :

g++ -Wall -g -std=c++17 ../../src/host.cpp -o app.exe -I${XILINX_XRT}/include/ -L${XILINX_XRT}/lib/ -lOpenCL -lpthread -lrt -lstdc++ -lxrt_coreutil
