Legacy ImageMagick Discussions Archive

I am trying to link my program with ImageMagick libs. I ran configure and then "make install". I am trying to statically link the libraries and the linker can find the libraries. The nm command shows that the symbols are in the libraries but I still cannot link. Every call into ImageMagick is met with an undefined reference.

: undefined reference to `Magick::Image::Image(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
: undefined reference to `Magick::Geometry::Geometry(unsigned int, unsigned int, unsigned int, unsigned int, bool, bool)'
: undefined reference to `Magick::Image::zoom(Magick::Geometry const&)'
: undefined reference to `Magick::Geometry::~Geometry()'
: undefined reference to `Magick::Image::write(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
: undefined reference to `Magick::Image::~Image()'

The sample programs built and ran so I am sure the compiler is fine. gcc version 3.4.6 20060404 (Red Hat 3.4.6-9)

Here is my link line:
linking @g++ -static -Wl,--allow-multiple-definition -L../utils/lib/release -L./bin/release -L../lib -L/usr/X11R6/lib -lMagick++ -lMagickCore -lMagickWand -lfreetype -lfontconfig -ldpstk -ldps -lXext -lXt -lSM -lICE -lX11 -lbz2 -lxml2 -lz -lm -lpthread -o bin/release/CmdLineClient ./obj/release/ImageMagick.o ./obj/release/CmdLineClient.o

Any help is greatly appreciated!!
Thanks,

Try this command:

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

Thanks! I had taken the output from the Magick-config and put it in my Makefile but obviously something went wrong. This will give me something to build on.

Any chance you could adapt that for someone trying to use ImageMagick in a program being compiled with Dev-C++ in Windows 7?

I've been trying to get rid of these linker errors for ages, and I can't find anyone else on the internet using Windows, Dev-C++, and ImageMagick that's getting these errors. >_<

I have the same problem as waffledonkey, tons of undefined reference messages for my sample program:
[Linker error] undefined reference to `Magick::Image::Image()'
[Linker error] undefined reference to `Magick::Image::read(std::string const&)'

etc...

I've tried adding the .dll to my project's folder, including CORE_RL_Magick++_.lib in the linker, everything I can think of. Help!
