undefined reference to xercesc_2_8 when compiling sample ocde

Question

I'm trying to compile the following sample code available at XERCES site:

#include <xercesc/util/PlatformUtils.hpp>
// Other include files, declarations, and non-Xerces-C++ initializations.
XERCES_CPP_NAMESPACE_USE

int main(int argc, char* argv[])
{
  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;
}

with,

g++ -g -Wall -pedantic -L/usr/lib -lxerces-c -o xercesTest xercesTest.cpp

giving me the following linking error:

/tmp/ccYIHCfR.o: In function `main':
/home/cjmv/temp/xercesTest.cpp:8: undefined reference to `xercesc_2_8::XMLUni::fgXercescDefaultLocale'
/home/cjmv/temp/xercesTest.cpp:8: undefined reference to `xercesc_2_8::XMLPlatformUtils::Initialize(char const*, char const*, xercesc_2_8::PanicHandler*, xercesc_2_8::MemoryManager*, bool)'
/home/cjmv/temp/xercesTest.cpp:18: undefined reference to `xercesc_2_8::XMLPlatformUtils::Terminate()'
/tmp/ccYIHCfR.o:(.gcc_except_table+0x10): undefined reference to `typeinfo for xercesc_2_8::XMLException'
collect2: ld returned 1 exit status

I've installed xerces-c28 and xerces-c2-dev through aptitude on my ubuntu-server 12.04

Any help would be appreciated.

Put the library last on the command line:

g++ -g -Wall -pedantic -L/usr/lib -o xercesTest xercesTest.cpp -lxerces-c
