I reference Edison Board Support Package User Guide (331188-001)
1. at 3.1 chapter, edison-image.bb file add:
IMAGE_INSTALL += "libpng"
flashing edison and run, but can not found /lib/libpng.*
2. at 3.3 chapter, add istall opencv, run "bitbake edison-image" can not download and compile opencv.
first question is no problem
second question is i add IMAGE_INSTALL += "opencv" to build/conf/local.conf, change to edison-image.bb file is ok!
