[FFmpeg-user] How to compile FFMPEG with OpenCL

[gllier]

Hello Guys:
I am using ffmpeg on keystone-II platform, need compile it with TI-OpenCL But when I add configure option --enable-opencl
It always prompts that： Error: opencl not found, this is my configure command:


./configure --prefix=/share/rootfs --enable-shared --cross-prefix=/ti/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin/arm-linux-gnueabihf- --arch=armv7  --target-os=linux --enable-gpl --extra-cflags=-I/share/rootfs/usr/include --extra-ldflags=-L/share/rootfs/usr/lib --enable-opencl 


I check config.log file, and find some information

I checked that missed library are in my configure directory,  DO NOT KNOW how to resolve it, Could you give some suggestion?
Thank you very much, and best wishes.
