5964,Linkage fails with cross-compiled boost.thread,anonymous,Anthony Williams,"I am cross-compiling boost 1.47
using

$ x86_64-w64-mingw32-g++ --version

x86_64-w64-mingw32-g++ (GCC) 4.5.4 20110822 (prerelease)

On Linux box with the following command:

./b2 -a toolset=gcc target-os=windows threading=multi threadapi=pthread
runtime-link=static --layout=versioned --build-type=complete install

user-config.jam contains the following:

using gcc : mingw  : x86_64-w64-mingw32-g++ ;

After that a linkage failed when building my project. I reproduced it with
simple test program:

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

using namespace std;

struct test
{
    void operator()() { cout << ""Called"" << endl; }
};

int main()
{
    test test_obj;
    boost::thread thr(test_obj);
    thr.join();
}

The output looks like

$ x86_64-w64-mingw32-g++ -Wall  test_boost.cpp -I
./3rdparty/boost/include/boost-1_47 -L ./3rdparty/boost/lib

The same scenario works fine when linking with dynamic libboost_thread. Both
static and dynamic builds work fine for Linux.


When I add define 

-DBOOST_THREAD_USE_LIB=1

it results in following:

I have reproduced it with boost 1.43, 1.46.1, 1.47 and latest (74606) revision from svn. Tried two differen mingw-w64 gcc versions: 4.5.4 and 4.7.0. ",Bugs,closed,To Be Determined,thread,Boost Development Trunk,Problem,invalid,,
