Question

Linking error RL Toolbox

Asked by: Gabriela1

HI guys,

I am trying to learn how to use a library named RL Toolbox,that is for reinforcement learning.  I want to use some of the functions of this library in my own project, but I do not understand how to use it. They give some examples and now I am trying to run the examples.
This is the link from where I downloaded the toolbox,

C:\Documents and Settings\ogvalent\Desktop\RLToolbox\Reinforcement Learning Toolbox1.mht

I downloaded the windows version.
I put both the

Linux
RL Toolbox 2.0 for Linux (Build 061004) (Download here)
The source files, including several examples how to use the toolbox. The toolbox is distributed as qmake project, so qmake is needed to compile the library. The archive additionally contains the external libraries for the toolbox.  
 
 I put both
RL Toolbox 2.0 Library for Win32 (Build 050824)  
RL Toolbox 2.0 Visual Studio 7.0 Project for Win32 (Build 050824)  

in the same folder and then I tried to run an example that they have there, ShortestPathVLearning.cpp
But I got some erros of linking

1>shortestpathVLearning.obj : error LNK2005: _main already defined in shortestpathQLearning.obj
1>libcpmtd.lib(xlock.obj) : error LNK2005: "public: __thiscall std::_Lockit::_Lockit(int)" (??0_Lockit@std@@QAE@H@Z) already defined in RL Toolbox Debug.lib(cqfunction.obj)
1>libcpmtd.lib(xlock.obj) : error LNK2005: "public: __thiscall std::_Lockit::~_Lockit(void)" (??1_Lockit@std@@QAE@XZ) already defined in RL Toolbox Debug.lib(cqfunction.obj)
1>libcpmtd.lib(xmutex.obj) : error LNK2005: "public: void __thiscall std::_Mutex::_Lock(void)" (?_Lock@_Mutex@std@@QAEXXZ) already defined in RL Toolbox Debug.lib(cqfunction.obj)
1>libcpmtd.lib(xmutex.obj) : error LNK2005: "public: void __thiscall std::_Mutex::_Unlock(void)" (?_Unlock@_Mutex@std@@QAEXXZ) already defined in RL Toolbox Debug.lib(cqfunction.obj)
1>LINK : fatal error LNK1104: cannot open file 'libcpd.lib'


 So probably I do not know how to link to what....because it is my first time trying to use a toolbox, so I do not have any experience in using libraries. I also found a manual for the library but they do not say what are the first steps in trying to use it, how to integrate it in your project.
If you can give some hints that will be great.
thanks!
