trouble with including ImageMagick in Xcode 4.1

[phluxy]

Hi everyone !

I have some problem with the use of the libraries in Xcode.
I am not very good but I would like to try to use ImageMagick libraries with Xcode on Mac OSX lion (10.7). I have already installed ImageMagick (version : 6.7.4-0 Q16) thanks to MacPorts.
The compilation works but when I execute the program I have to kill it with some errors about bzip2 and I don't understand... why bzip2 ?

The code is very simple (only to understand how it works) :

Code: Select all

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <magick/api.h>
#include <magick/ImageMagick.h>

int main(int argc, const char * argv[]) 
{
    ExceptionInfo *exception;
    Image *image, *scaled_image;
    ImageInfo *image_info;
    
    /* Initialization of ImageMagick and useful structures */
    MagickCoreGenesis(*argv,MagickTrue);
    exception=AcquireExceptionInfo();
    image_info=CloneImageInfo((ImageInfo *)NULL);
    
    /* Reading an image */
    strcpy(image_info->filename,"image.bmp");
    image=ReadImage(image_info,exception);
    
    /* Reduces the size of an image */
    scaled_image=ResizeImage(image,320/4,240/4,LanczosFilter,1.0,exception);
    if (scaled_image != (Image*) NULL)
    {
        DestroyImage(image);
        image=scaled_image;
    }
    
    /* Saving the image in JPEG format and deallocation */
    strcpy(image->filename, "image.jpg");
    WriteImage(image_info,image);
    DestroyImage(image);
    
    /* Closing Imagemagick */
    MagickCoreTerminus();
    return(0);
    
}

the return of the program :

There is nothing in this folder "/opt/local/var/macports/build/"... but I have bzip2 installed on my system...

You need to check for exceptions. It looks like your program could not read image.bmp, only the exception will tell you why. Try this code:

Code: Select all

if (image == (Image *) NULL)
  CatchException(exception);

Now it works !
I have to put the whole path of the file even if the file is on the root of the project...

Thanks for your help !
