Using Imagemagick lib

Hi,

I've been trying to get Imagemagick working in my Qt project. Because I'm using MinGW compiler, I had to build the Imagemagic lib myself. I followed these instructions: http://imagemagick.sourceforge.net/h...w/install.html

My .pro file looks like this:

Code:

INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/magick"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/Magick++"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/wand"
LIBS += -Lc:/MinGW/lib -llibMagickWand-6.Q16 -llibMagickCore-6.Q16

I have added headers to .cpp and it seems to work:

Code:

#include <Magick++.h>

Then I have tried to copy the related 'dll' and 'a' files under mingw/lib and the application directory.

Problem is that it gives following errors when building the project:

Code:

Any idea what is causing the errors? By googling I found some comments that some other libs should also be added, but at least these did not make any change:

Code:

LIBS += c:/MinGW/lib/libkernel32.a
LIBS += c:/MinGW/lib/libgdi32.a

On the other hand, if I do not put the -Lc:/MinGW/lib to the .pro file (only the two libraries), it seems that the added libraries are not found:

.pro:

Code:

INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/magick"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/Magick++"
INCLUDEPATH += "C:/ImageMagick-6.8.8-Q8/include/wand"
LIBS += c:/MinGW/lib/libMagickCore-6-Q16.a
LIBS += c:/MinGW/lib/libMagickWand-6-Q16.a

Then trying to use the libraries in source:

Code:

Magick::Image magick;

build error:

Code:

Don't know anymore what to try. Any help is higly appreciated! Thanks!
