Compiling problem with Magick++ on Ubuntu 12.04.2 LTS 64bit

Post by Caffeinomane » 2013-02-05T02:04:29-07:00

Hello, I am using a Ubuntu 12.04.2 LTS 64bit and I am trying to compile this simple program that I found somewhere on this forum:

Code: Select all

#include "Magick++.h"

using namespace std;
using namespace Magick;

void testbild()
{
  Image  image;
  image.read( "logo:");
  Geometry newSize = Geometry(720, 480);
  image.scale(newSize);
  image.write( "logo.png");
}

int main(int argc, char **argv)
{
   InitializeMagick(*argv);
   testbild(); // OK
   return 0;
}
But g++ refuses to compile it:

Code: Select all

$ g++ `Magick++-config --cppflags --cxxflags --ldflags --libs` -o prova prova.cpp
/tmp/cc2BtIjx.o: In function `testbild()':
prova.cpp:8: undefined reference to `Magick::Image::Image()'

Yes I have installed the development package of this library

I tried every combination of g++ options that I could find but nothig succeded. Does someone has any suggestion before I give up and use another library?

Seems we are having the same issue, just posted a similar message in the board, but using ubuntu 12.10 and i686 (also tested with x86_64).

Could you fix this?

Here is the proper build command for a Magick++ module:
  • g++ `Magick++-config --cxxflags --cppflags` -O2 -Wall -o magick++ magick++.cpp `Magick++-config --ldflags --libs`
Post the output of that command if it fails.

How would this apply to code divided in multiple files? i've tried to adapt this to the makefile I posted in my thread (viewtopic.php?f=23&t=22864) but I've had no success so far, it fail building the "main" target (when the linkage is done) Any help is greatly appreciated
