When trying to load an image in octave using the imread command (which is part of the port octave-forge-image) dynamic link errors messages occur: octave-3.0.2:1> X = imread('test.jpg'); error: /usr/local/libexec/octave/packages/image-1.0.8/amd64-portbld-freebsd7.0-api-v32/__magick_read__.oct: Undefined symbol "_ZTIN6Magick9ExceptionE" error: `__magick_read__' undefined near line 73 column 33 error: evaluating if command near line 72, column 5 error: called from `imread' in file `/usr/local/share/octave/packages/image-1.0.8/imread.m' error: evaluating assignment expression near line 1, column 3 Fix: The problem is that __magick_read__.oct isn't linked against libMagick++.so Compiling as follows fixes the problem: mkoctfile __magick_read__.cc `Magick++-config --cppflags` `Magick++-config --ldflags --libs` In other words the --libs is necessary for successful dynamic linkage. How-To-Repeat: 1) Install port octave-forge-image 2) Try loading an image using the imread command.

The attached patch seems to accomplish what he intended, and I approve of it.
Responsible Changed From-To: freebsd-ports-bugs->amdmi3 I'll take it.
State Changed From-To: feedback->open Feedback with a patch received from maintainer.

This is because it seems that imread and imwrite are part of octave-3.2.x. But in the FreeBSD ports, not even octave-devel goes that high in development number! Really, this message is just a point of information, just so you expect it if or when it happens.
