Hi,
I was able to remove opencv and successfully build by doing the following:
Edit ./meta-clanton-distro/recipes-core/images/image-full.bb and remove opencv and python-opencv from IMAGE_INSTALL
Delete ./meta-clanton-distro/recipes-support/opencv/opencv_2.4.3.bbappend
Delete ./meta-oe/meta-oe/recipes-support/opencv/opencv_2.4.3.bb
Delete ./meta-oe/meta-oe/recipes-support/opencv/opencv-samples_2.4.3.bb
I'll be using the malinov recommendations and building the larger build today, but maybe tomorrow I'll look at building 2.4.9. Let me know if you are successful.
Bill
