Question

我尝试在anjuta中的http://www.imagemagick.org/script/magick-wand.php中编译ImageMagic c代码。我成功下载并编译了ImageMagic 然后从project-＆gt; Add Library ...

将库添加到anjuta

然后我尝试运行以下链接

中的代码

#include <stdio.h>
#include <stdlib.h>
#include <wand/MagickWand.h>

int main(int argc,char **argv)
{
#define ThrowWandException(wand) \
{ \
  char \
    *description; \
 \
  ExceptionType \
    severity; \
 \
  description=MagickGetException(wand,&severity); \
  (void) fprintf(stderr,"%s %s %lu %s\n",GetMagickModule(),description); \
  description=(char *) MagickRelinquishMemory(description); \
  exit(-1); \
}

MagickBooleanType
  status;

MagickWand
  *magick_wand;

if (argc != 3)
  {
    (void) fprintf(stdout,"Usage: %s image thumbnail\n",argv[0]);
    exit(0);
  }
/*
  Read an image.
*/
MagickWandGenesis();
magick_wand=NewMagickWand();  
status=MagickReadImage(magick_wand,argv[1]);
if (status == MagickFalse)
  ThrowWandException(magick_wand);
/*
  Turn the images into a thumbnail sequence.
*/
MagickResetIterator(magick_wand);
while (MagickNextImage(magick_wand) != MagickFalse)
  MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
/*
  Write the image then destroy it.
*/
status=MagickWriteImages(magick_wand,argv[2],MagickTrue);
if (status == MagickFalse)
  ThrowWandException(magick_wand);
magick_wand=DestroyMagickWand(magick_wand);
MagickWandTerminus();
return(0);
}

但我得到了这个错误。

main.c'.35: undefined reference to ‘MagickWandGenesis'

请帮我解决这个问题

我想我找到了解决方案，安装libmagickwand-dev程序后正常使用，sudo apt-get install libmagickwand-dev命令我将MagicWand添加到项目中的库 - ＆gt;将库添加到anjuta -

将Imagemagick C库与anjuta一起使用
