A possibility. Simulate the DllMain DLL_PROCESS_DETACH through a member function call in the thread class which should only be used for those who are using a static library version of the library. The member function must be called before the thread function exits in the static library version. For the DLL version, the member function must be ignored or you can simply not have the member function call in the DLL version. The onus would be on those using the static library version to always make this call before their thread function exits, but would at least provide them wioth the possibility of using a static library version. Of course there may be other ramifications which cause this idea not to work, or even getting it to work properly would be too much trouble, but I thought I would suggest it anyway. It may not be worth thinking about possible solutions of building a static library version of Boost.Threads. I know that for myself I always creates DLLs when distributing applications but as a 3rd party developer I always leave open the possibility that there are people who like to distribute the applications as a single EXE which uses static libraries and the static library version of their compiler's RTL. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
