I have never added a library to Dev-C++. I read the guide here.

So I added two lines of code to my cpp file:

#include "pugixml.hpp"
#include "pugiconfig.hpp"

But I get errors like this:

[Linker error] C:\Users\MATRIX~1\AppData\Local\Temp\ccYfRAuS.o:2.visualizza tutto.cpp:(.text+0xbc): undefined reference to `pugi::xml_document::xml_document()'

Can someone tell me how to do this in Dev-C++? I need to create a simple program that reads the XML that I created.

    What's your problem? There's no difference between devc++ or any other c++ editor/ide/compiler with respect to include syntax. Have you forgotten #s? – Dmitry Ledentsov Dec 06 '13 at 15:28
  • @DmitryLedentsov It's a linker error, meaning that there's no problem with the syntax. Linking is done after the syntax check. It usually means you forgot to write the implementation of a function or misspelled its header, or your compiler doesn't know where the implementation is (in this case). – leewz Dec 06 '13 at 15:51

You need to add the pugixml libraries. In Dev-C++ go to your project's linker settings and find the pugixml .lib files and add them.

    To expand: In general, with outside libraries, there are header files (declaring things) and there is object (not C++ objects) code (defining those things). Since the same header file can have different implementations, you have to point Dev-C++ to the compiled code. – leewz Dec 06 '13 at 15:48
  • There is no pugixml .lib in the pugixml zip file. I have .hpp and .cpp files – newtphp Dec 06 '13 at 17:32
  • You probably need to compile the library. Alternatively, you can try to find a pre-compiled version of it. – austin Dec 06 '13 at 17:42
  • Do you know where I can find even other precompiled library for xml parsing? I need to create an exe application ( DOS style graphic) which show the content of an xml file. Not the tags only the content and I need to add a description for the information in every tag. – newtphp Dec 06 '13 at 17:48

You don't need .lib file, you need to add pugixml.cpp to compilation. In Dev-C++ menu choose "Project" - > "Add To Project..." and choose pugixml.cpp.

Add the existing files' path to the include directory, then add the existing files to your project.

Then you will be able to reference them in #include and also in written code.
