Hi all,


I want to cross compile OpenCV library on an imx6 board using meta toolchain (Yocto)

Here's the steps I've done:

- building the meta toolchian

bitbake meta-toolchain

- building OpenCV image

bitbake opencv

-adding opencv to the image (adding opencv recipe) by changing the local config file

       opencv \

- building the toolchain again

bitbake meta-toolchain

- install the toolchain

sudo sh \ 

- setup the toolchain environment

source \ 



No I'm having a hard time cross compiling a sample openCV code.

I can see opencv libraries and include files on the Yocto directory (build directory) but I don't see them on /opt/poky/<version/ (which I guess is the directory for cross compilation)

( simple c code is compiled perfectly but there's no opencv libraries and include files to compile opencv)


is there a step I missed to build the toolchain to create openCV files?


any suggestions would be great
