Unable to compile OpenCV with OpenCL support (Yocto Zeus IMX8MPlus)

Good day everyone,

I am using the lastest version of meta-openembedded for zeus  with I.MX 8M Plus as target. 

MACHINE ??= 'imx8mp-vpb'
DISTRO ?= 'vpb-imx-xwayland'

 

For my program, I need to implement an OpenCL kernel to perform a per-element operation on a OpenCV UMat. As I understand, I must first compile OpenCV with the option WITH_OPENCL.

This is the whole opencv recipe:

This a snippet of the CMakeLists.txt of OpenCV (CV_DISABLE_OPTIMIZATION is turned off):

OCV_OPTION(WITH_OPENCL "Include OpenCL Runtime support" (NOT ANDROID AND NOT CV_DISABLE_OPTIMIZATION)
  VISIBLE_IF NOT IOS AND NOT WINRT
  VERIFY HAVE_OPENCL)

 

Nevertheless, when I compile it, this is the output I get:

Where there's no mention at all of OpenCL. Also, the generated cvconfig.h includes:

/* OpenCL Support */
/* #undef HAVE_OPENCL */
/* #undef HAVE_OPENCL_STATIC */
/* #undef HAVE_OPENCL_SVM */

which if I understand correctly, means OpenCL is not used.

 

If I try to run my program using OpenCL in the target, I get errors related with OpenCV not being compiled with OpenCL.

 

Maybe you could help me with this? Is this some misconfiguration of my Yocto environment, or am i missing something?

 

Thank you in advance,

Carlos Durán

Please try to use the latest version of the i.MX8MP BSP.

 

You could build the Yocto BSP by following the i.MX Yocto Project User’s Guide​.

(FYI. More details of the Linux Yocto BSP from here: https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...)

 

The i.MX Graphics User’s Guide include the GPU support information of i.MX8MP.

The i.MX Linux Reference Manual​ Chapter 5 include the GPU drivers and library files information.

Thank you for your reply. Unfortunately, upgrading the Yocto version is not an option as of now due to current work load.
