Custom coders don't compile on Linux.

[epi]

MagickCoderKit and any other custom coder based on it don't compile on Linux because of missing header files (at least).
./configure passes without problems, but make does not:

Code: Select all

(ImageMagick 6.6.9-5 Q16)

Copying all headers from IM sources into /usr/local/include/ImageMagick/magick/ solve the problem, but still I think all headers needed to build custom coders should be copied there during installation (as it used to be or as it is still in Windows).

The MagickCoderKit is a low-level kit that requires a number of non-installed private header files only found in the ImageMagick source distribution. The simplest solution is to add a -I/path/to/IM-source to the compile command line.
