Cannot get the ImageMagick Magick++ library to link properly

gergnnud

This is driving me nuts.

I have tried for many weeks it seems to get QT to recognise the Magick++ library properly without success.

I have tried various ImageMagick installs to no avail.

Extract from my .pro file

win32 {
   RC_FILE = tlcm.rc
}

mac {
    ICON =
    QMAKE_INFO_PLIST = Info_mac.plist
    TARGET = My-App

    # No 64-bit Flash on Mac, so build the browser 32-bit
    contains(QT_CONFIG, x86) {
        CONFIG -= x86_64
        CONFIG += x86
    }
    contains(QT_CONFIG, ppc) {
        CONFIG -= ppc64
        CONFIG += ppc
    }
}

SUBDIRS += \
    imageviewer.pro

#Libraries
LIBS += -L$$PWD/../../../../../opt/local/lib/ -lgphoto2

INCLUDEPATH += $$PWD/../../../../../opt/local/include/gphoto2
DEPENDPATH += $$PWD/../../../../../opt/local/include/gphoto2

LIBS += -L$$PWD/../../../../../opt/local/lib/ -lMagick++-6

INCLUDEPATH += $$PWD/../../../../../opt/local/include/ImageMagick-6
DEPENDPATH += $$PWD/../../../../../opt/local/include/ImageMagick-6

So gphoto2 is recognised and working but Magick++-6 is not. The error on compile of course is;
library not found for -lMagick++-6
linker command failed with exit code 1 (use -v to see invocation)

The symlink is definitely there in /opt/local/lib/ as libMagick++-6.Q16.dylib

I tried re-installing from macports today and relinking via ‘Add Library’ but still no success. The reason for a re-install of ImageMagick was because I had previously got QT to recognise this library but then I was confronted with a huge list of errors about quantum depth etc. - errors in the library files so that can’t be right. Now doesn't even link using the same method.

Running on a Mac of course (Yosemite, QT 5.3.1). Any thoughts?

Hi,

LIBS += -lMagick++-6.Q16

should to the trick
