1053	Error using boost::mutex and C++/CLI	fpelliccioni@…	Anthony Williams	"Hello, 


I have the following code:


//---- first.h

#ifndef _first_h_included_
#define _first_h_included_

#include <boost/thread/mutex.hpp>
#include <iostream>
#include <string>

namespace test_first
{
	static boost::mutex io_mutex; 

	struct console
	{

	public:

		static void write(std::string s);

	};
}

#endif


//---- END first.h


//---- first.cpp

#include ""first.h""


namespace test_first
{
	void console::write(std::string s)
	{
		{
			boost::mutex::scoped_lock sl(io_mutex);
			std::cout << s;
		}
	}
}

//---- END first.cpp


I compile this code using Visual Studio 2005 as a LIB file.
I compile withOUT /CLR option.


The problem is in the next file, ""executable.cpp"".


//---- executable.cpp
#include <string>
#include ""first.h""



int main (int argc, char *argv[])
{
	test_first::console::write(""fer"");

	std::cin.get();
	return 0;
}
//---- END executable.cpp



When I try to use this LIB in a C++/CLI source file, compiled with /CLR option, I have the followings errors:


Error	1	error LNK2005: ""public: void __thiscall std::_Mutex::_Lock(void)"" (?_Lock@_Mutex@std@@QAEXXZ) already defined in msvcprt.lib(MSVCP80.dll)	libcpmt.lib	

Error	2	error LNK2005: ""public: void __thiscall std::_Mutex::_Unlock(void)"" (?_Unlock@_Mutex@std@@QAEXXZ) already defined in msvcprt.lib(MSVCP80.dll)	libcpmt.lib	

Error	3	fatal error LNK1104: cannot open file 'libboost_thread-vc80-mt-s-1_34.lib'	Executable	



The boost::mutex LIB file that I use is: ""libboost_thread-vc80-mt-1_34.lib"".

Thanks to all.
