Hello! I downloaded tinyxml (2.6.1), put it as prescribed in my project folder, registered it in the project file

#include "tinyxml/tinyxml.h" #include "tinyxml/tinystr.h"

I refer from the function main () to the functions of the library. But when building a project, the linker swears:

In the code I checked - all these functions are declared and reserved, the compiler sees them.

  • And the linker sees the library file? - Harry
  • Here's how to make the linker see this header file? In general, no lib for this tinyxml is supposed ... I have MS Visual Studio 2015 Professional. - AVM
  • You confuse compiler with linker. - nick_n_a
  • Do you have a dll? Do you have a lib? There are two ways to connect the finished code with the dll 1. Lib-file (prescribe or in the linker option or pragma) It’s easier to download lib in nete and register in the project. 2. Def-file where you prescribe the alias relation ?? 0TiXmlDocument @@ QAE @ XZ to the function in the dll (in principle, lib is approximately equal to def). This method works, but more difficult, is used as an extreme case. - nick_n_a
  • If the aliases inside the library are the same as yours written (?? 0TiXmlDocument @@ QAE @ XZ, you can see them, let's say, with the exescope utility), then the lib file can be created with the implib utility. - nick_n_a
