How to build an OpenCV project using ARM compiler 6

I am trying to build a C++ OpenCV project with ARM compiler 6 in ARM development studio ide. I already, downloaded version 3.2.0 from the GitHub repository of OpenCV and built it for the MinGW compiler using CMake GUI in windows. When I configure my project to use MinGW, I can cross-compile my code an generate the axf file without any problem. However, when I use ARM compiler 6 I'm getting the build report attached below., my questions are, what can I do to resolve the reported errors ? Do I need to re-build the OpenCV library for ARM compiler 6? If so which generator and platform should I choose in CMake GUI?

Hi, It looks like you have exception support disabled using the -fno-exceptions, but you're compiling code that throws exceptions. You can find the latest AC6 reference guide here: https://developer...
