Cannot get the ImageMagick Magick++ library to link properly
-
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
