c++ - Error building openCV - dumpOpenCLDevice() method error -


i have been trying build opencv on week using instructions @

http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html , http://miloq.blogspot.com/2012/12/install-opencv-ubuntu-linux.html every time 'make' step, error:

the process works while , stops @ 79% above error. thought problem might caused fact did not have opencl library installed. installed shown @ www.amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/07/amd_app_sdk_installation_notes.pdf , still no luck. running ubuntu 12.04 , opencv 2.4.9. installed version of amd app sdk 2.8.1.0. please help. @ wits end here.

i experienced same problem , solved me compiling opencv without modules needing gpu functionality using following cmake command in release folder:

cmake -d cmake_build_type=release -d cmake_install_prefix=/usr/local -d with_opencl=off -d with_cuda=off -d build_opencv_gpu=off -d build_opencv_nonfree=off -d build_opencv_stitching=off -d build_opencv_superres=off ..

the following modules deactivated: gpu, nonfree, stitching, superres

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
