[Octave-bug-tracker] [bug #39913] Unable to compile __magick_read__.cc after cset ba79ba4e83ab

[Carnë Draug]

Follow-up Comment #1, bug #39913 (project octave):

Going through the NEWS file of GraphicsMagick[1], I see that LZMA compression
was added in 1.3.13 (released on December 24, 2011). However, I don't see
mention of JPEG200 and JBIG in the NEWS. It could be that it was omitted from
the NEWS of because it has been there for a very long time but it's disabled
in your build of GraphicsMagick.

Can you please check with "gm version -verbose" if it's mentioned support for
the formats JBIG and JPEG-2000? Mine reports the following:


Feature Support:
  Thread Safe              yes
  Large Files (> 32 bit)   yes
  Large Memory (> 32 bit)  yes
  BZIP                     yes
  DPS                      no
  FlashPix                 no
  FreeType                 yes
  Ghostscript (Library)    no
  JBIG                     yes
  JPEG-2000                yes
  JPEG                     yes
  Little CMS               yes
  Loadable Modules         no
  OpenMP                   yes (201107)
  PNG                      yes
  TIFF                     yes
  TRIO                     no
  UMEM                     no
  WMF                      yes
  X11                      yes
  XML                      yes
  ZLIB                     yes


If the problem has to do with disabled features, then there will be a lot of
ifdefs in __magick_read__.cc
