Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
Take a look at config.log to determine what ImageMagick did not like about your c++ compiler or c++ headers. Fix the problem and rerun the configure script until Magick++ is validated. If you don't need the C++ API you could always install without building Magick++.
