5921	MingW Boost linking	sergio.d		"Dear all,

I am trying to link boost thread 1.47 using Mingw version 4.6.1.
I already applied the modification proposed in #4614; that is I added the or condition for defined(MINGW32) on line 40 of the file config.hpp. The other suggestion in #4258 cannot be applied due to the fact that the file tss_pe.cpp seems not to exist anymore.
After the modification I recompiled all the library using gcc as --toolset option.

In particular I get the following linking-time errors.

Surface.o:Surface.cpp:(.text+0x1833): undefined reference to `boost::thread::~thread()'
Surface.o:Surface.cpp:(.text+0x1d07): undefined reference to `boost::thread::hardware_concurrency()'
Surface.o:Surface.cpp:(.text+0x20f4): undefined reference to `boost::thread::start_thread()'
Surface.o:Surface.cpp:(.text+0x23a2): undefined reference to `boost::thread::start_thread()'
Surface.o:Surface.cpp:(.text+0x250b): undefined reference to `boost::thread::join()'
Surface.o:Surface.cpp:(.text+0x26fb): undefined reference to `boost::thread::~thread()'
Surface.o:Surface.cpp:(.text+0x34b8): undefined reference to `boost::thread::~thread()'
Surface.o:Surface.cpp:(.text+0x35c3): undefined reference to `boost::thread::~thread()'

If I use the unmodified boost library I get the same errors.
Additionally I already recompiled bjam and I both used b2 and the recompiled bjam with no success. In any case the boost library is succesfully built and I get linking errors only when linking from my sources.
The same sources and makefile work well on Linux; they work also in Window using Visual Studio and boost threads again in version 1.47.

Any suggestion?
