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? Thanks

It seems you need to link with the thread library. Could you post the exact command line the made these errors?
