I have set up a cross compilation Windows -> Raspberry following the Hello world example.
I’m curious how can I use OpenCV with this setup ? Shall I first install it on the raspberry and then copy all files back to Windows machine (dev machine) ?
Yes, you should first install the library on the Raspberry Pi itself and then resynchronize the sysroot. You can resynchronize the sysroot on the Makefile settings page in VisualGDB Project Properties.
