[Boost-users] Linking problem with Borland C++ 5.6

I try to compile a simple thread_group-example with Borland C++ 5.6 for
Win32. I get the following link error:

 

Error: Unresolved external 'boost::thread_group::create_thread(const
boost::function0<void, std::allocator<boost::function_base> >&)'
referenced from

C:\BACPP\SERVICEADAPTER\SRC\SERG.OBJ

 

I have built the boost_thread-bcb-mt-1_34_1.lib with Bjam and Borland. 

The examples can be created with the library.

 

The MSVC-Variant works without errors.

Any idea?????
