porting Opencv_2.4.10 to IMX6q board

[lifrank]

Hi All:

         I'm trying to port opencv_2.4.10 to imx6q board. I's using the toolchain:arm-fsl-linux-gnueabi.  Also I'm using CMake to generate the makefiles. But when I trying to make ,here is the error messages.

frank@ubuntu:~/Project/opencv-2.4.10/cross-build$ make

Hi frank,

Looks like you dependency issues, such as > python 2.7, please check your requirements and dependencies packages that you need to install for OpenCV 4.0.

Cross compilation for ARM based Linux systems — OpenCV 2.4.11.0 documentation

Hi Bio:

   I have build the same OPENCV_2.4.10 version right by not using the cross-compiler. It works fine. But when I tried to usetoolchain:arm-fsl-linux-gnueabi to port the opencv to my imx6q board,  it failed. I'm not sure its the problem of dependency issuse.
