Re: imread(): libGraphicsMagick++.so.3: cannot open shared object file: No such file or directory

The "imread()" problem was solved with defining:
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/.../graphics_magick-1.3.21_g++_5.1/lib/pkgconfig
and rebuilding octave from source.

thanks,

Following the bug #45569 report, I was asked to email in the help mailing list about the problem for running "imread".

I have installed octave-4.0.0 (with g++5.1) from source with the distros "GraphicsMagick" (from binary rpm based on g++4.4.7).
Then built image-2.4.0 (with g++5.1). After the octave build, because of the " D_GLIBCXX_USE_CXX11_ABI" issue, I installed "GraphicsMagick" from source with g++5.1 (added the path in LD_LIBRARY_PATH) and removed the distro "GraphicsMagick". Then the "imread" call gives the error:

a=imread(fname)

error: default_formats: /usr/.../octave-4.0.0_g++_5.1/lib/octave/4.0.0/oct/i686-pc-linux-gnu/__magick_read__.oct: failed to load: libGraphicsMagick++.so.3: cannot open shared object file: No such file or directory

with the following information:

ldd /usr/.../lib/octave/4.0.0/oct/i686-pc-linux-gnu/__magick_read__.oct| grep -i magick
libGraphicsMagick++.so.3 => not found
libGraphicsMagick.so.3 => /usr/.../graphics_magick-1.3.21_g++_5.1/lib/libGraphicsMagick.so.3 (0x001b3000)

The folder "/usr/.../graphics_magick-1.3.21_g++_5.1/lib" contains the following libs:

libGraphicsMagick++.so.11.0.0
libGraphicsMagick++.la
libGraphicsMagick.la
libGraphicsMagick.so -> libGraphicsMagick.so.3.13.0
libGraphicsMagick++.so.11 -> libGraphicsMagick++.so.11.0.0
libGraphicsMagickWand.so.2 -> libGraphicsMagickWand.so.2.7.1
libGraphicsMagickWand.so -> libGraphicsMagickWand.so.2.7.1

libGraphicsMagick++.so -> libGraphicsMagick++.so.11.0.0
libGraphicsMagickWand.so.2.7.1
libGraphicsMagickWand.la
libGraphicsMagick.so.3.13.0

If I add a link into the folder "/usr/.../graphics_magick-1.3.21_g++_5.1/lib":
libGraphicsMagick++.so.3 -> libGraphicsMagick++.so (pointing to: libGraphicsMagick++.so.11.0.0)

octave gives the error:
