xerces c++ and cmake

Question

i tryng to build a small example of Xerces with xerces c++ 3.1 and cmake, but i and only getting linkings problems. This is my cmkelists.txt:

//============================================================================
project(ConfiguradorXerces)
cmake_minimum_required(VERSION 2.8)
include_directories (/home/ricardo/Desktop/librerias/xerces/xerces-c-3.1.1/src)
link_directories (/home/ricardo/Desktop/librerias/xerces/xerces-c-3.1.1/src/.libs)
link_directories (/home/ricardo/Desktop/librerias/xerces/xerces-c-3.1.1/src/)
set ( XercesLib  xerces-c )
aux_source_directory(. SRC_LIST)

add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${XercesLib})
//==============================================

//===============================================

#include <iostream>
#include <xercesc/util/PlatformUtils.hpp>
using namespace xercesc;
using namespace std;
int main()
{
    try {
        XMLPlatformUtils::Initialize();
      }
      catch (const XMLException& toCatch) {
        // Do your failure processing here
        return 1;
      }

      // Do your actual work with Xerces-C++ here.

      XMLPlatformUtils::Terminate();

      // Other terminations and cleanup.
      return 0;
}

//==============================================

and this is my console output:

CMakeFiles/ConfiguradorXerces.dir/main.cpp.o: In function `main':

// i was thinking trhat my cmakeLsits.txt was not complete, there is an especial setup that it has to be done?? thx in advance

Answer 1

I am pretty sure that target_link_libraries() macro accepts a target as its first parameter:

  target_link_libraries(<target> [item1 [item2 [...]]]
                        [[debug|optimized|general] <item>] ...)

And you have forgot to specify it. So instead of target_link_libraries(${XercesLib}), try target_link_libraries(${PROJECT_NAME} ${XercesLib}).

Hopefully, that solves it.
