hi,

I've got a bit of experience with PHP, Java, etc., but new to C++. I'm just trying to compile one of the test programs found in Magick++. I am using ubuntu linux , Eclipse 3.2.2, and CDT 3.1.2. here is what I have done so far.

- File>New>Managed Make C++ project
- File>New>Source File, created a new file main.cpp
- copy/paste code from ./ImageMagick-6.5.1-0/Magick++/tests/readWriteImages.cpp to main.cpp

Code: Select all

// This may look like C code, but it is really -*- C++ -*-

#include <Magick++.h>
#include <string>
#include <iostream>
#include <list>
#include <vector>

using namespace std;

using namespace Magick;

int main( int /*argc*/, char ** argv)
{

  // Initialize ImageMagick install location for Windows
  InitializeMagick(*argv);

  int failures=0;

[ plus a bit more...]

- Project>Properties>C/C++ Build>GCC C++ Linker > Miscellaneous>Linker Flags, added

Code: Select all

`Magick++-config --cppflags --cxxflags --ldflags --libs`

- Project>Properties>C/C++ Build>GCC C++ Compiler>Directories, added

Code: Select all

/path/to/ImageMagick-6.5.1-0/Magick++/lib

- When I "Build Project" I get the following output

Code: Select all

**** Build of configuration Debug for project test ****

- right click on main.cpp, choose Properties>C/C++ Build>GCC C++ Compiler>Directories, added

Code: Select all

/path/to/ImageMagick-6.5.1-0/Magick++/lib

Now when I "Build Project" the compiler finds Magick++.h, but I get these errors:

Build complete for project test

Can someone offer a suggestion as to what I'm doing wrong?

Many thanks.

Try the following. Copy readWriteImages.cpp to a folder somewhere and type

g++ `Magick++-config --cxxflags --cppflags` -o readWriteImages readWriteImages.cpp `Magick++-config --ldflags --libs`

Does that build / execute for you? Works for us of course.

It worked.

for those who follow, the problem was as follows:
- installed eclipse & CDT using apt-get
- downloaded Imagemagick source to /path/to/Imagemagick
- tried to config Build to point to Magick++ source. didn't work.

- when I ran g++ from the command line, I discoverd that `Magick++-config` could be found in "libmagick++9-dev"
- ran "sudo apt-get install libmagick++9-dev"
- removed all the references to /path/to/Imagemagick because apt-get did everything for me

and voila. it works.
