[Boost-users] error while loading shared libraries

Greetings all,

I first created a class for a library like this:

library.h:

class Library
{ 
public:
   Library() { };
   ~Library() { };
   void testLib();  
};

library.cpp:

#include "library.h"
#include <boost/thread/mutex.hpp>
#include <boost/thread.hpp>
#include <iostream>
using namespace std;

void Library::testLib()
{
   boost::thread* lt;
   boost::mutex mu;

   boost::mutex::scoped_lock lock(mu);
   cout << "test!" << endl;
}

I then created the static library like so:

g++ -I ~/boost_1_38_0/  -c library.cpp 
ar rcs libtest.a library.o

and then I created a main.cpp like so:

#include "library.h"
#include <iostream>
using namespace std;

int main()
{
   Library l;
   l.testLib();
}

now when I try to compile main.cpp like this:

$ g++ -I ~/boost_1_38_0/ -I. main.cpp -o main -L/usr/local/lib/ -L. -ltest
-lboost_thread-gcc41-

now when I run main:

$ ./main
./main: error while loading shared libraries:
libboost_thread-gcc41-mt-1_38.so.1.38.0: cannot open shared object file: No
such file or directory

I get that error. 

Can anyone explain why?
