Error using boost::mutex and C++/CLI

[fpelliccioni@…]

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. Fernando Pelliccioni. Buenos Aires, Argentina.

Complete Source Code

Not really sure if that's the problem but using the static versions of the C Run-Time Library (LIBCPMT.LIB, LIBCPMTD.LIB) not possible when compiling mixed/managed code (e.g. C++/CLI with /CLR).

See ​http://msdn2.microsoft.com/en-us/library/abx4dbyh(VS.80).aspx

You cannot use the statically linked CRT ( /MT or /MTd options) with /clr. Use the dynamically-linked libraries (/MD or /MDd) instead.

Sorry for the delay.

The problem is solved.

Thank you very much.
