OpenCL in IMX8MQEVK

pachedo — Tue, 30 Apr 2019 10:32:04 GMT

I'am having trouble following Diego Dorto tutorials.

https://diegodorta.com.br/yocto/Setting-Up-Yocto.html

https://diegodorta.com.br/gpu/OpenCL-Overview.html

In second when I try to do

$ $CC hello.cpp -o hello -Wl,--library-path=<PATH_TO_LIB>,\  -rpath-link=<PATH_TO_LIB> -lm -lOpenCL

I get the following output

hello.cpp:1:19: fatal error: CL/cl.h: No such file or directory

So I added

$ $CC hello.cpp -o hello -Wl,--library-path=<PATH_TO_LIB>,\  -rpath-link=<PATH_TO_LIB> -I/usr/include -lm -lOpenCL

and I get the following output

/opt/fsl-imx-xwayland/4.9.51-mx8-ga/sysroots/x86_64-pokysdk-linux/usr/libexec/aarch64-poky-linux/gcc/aarch64-poky-linux/6.2.0/real-ld: cannot find -lOpenCL

I think that I didn't built an image and respective sdk with OpenCL

My local.conf:

MACHINE ??= 'imx8mqevk'
DISTRO ?= 'fsl-imx-xwayland'
PACKAGE_CLASSES ?= "package_rpm"
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"

Hi Luis,

I can not enter the link you showed up, but in general try the L4.14 it includes support for OpenCL.
