Hi, i tried my proposal on Jessie. After
./configure --enable-hdri i see Options used to compile and link: ... CPPFLAGS = -DMAGICKCORE_HDRI_ENABLE=1 -DMAGICKCORE_QUANTUM_DEPTH=16 while "make" it reports lines like CC magick/magick_libMagickCore_6_Q16HDRI_la-histogram.lo I then run (without "make install"): ./utilities/identify | fgrep Features and get Features: Cipher DPC HDRI OpenMP ------------------------------------------------- What do you get from the not yet installed binary ? ImageMagick-6.9.3-4/utilities/identify Have a nice day :) Thomas
