Intentionally removed. In the current library it's easier to deal with a single build type, and since a DLL is required for TLS usage, the static build was removed. In the next version of the library, the implementation is going to have to make use of TLS as well, so you'll always need a DLL, making it pointless to continue providing both a static library and the threadmon.dll.

If you mean something other than Transport Layer Security when you say TLS, disregard the rest of this and just let me know what it means in boost-ese.

Sorry, I forget that some acronyms aren't known by everyone. TLS stands for "thread local storage", also known as TSS or "thread specific storage".

I don't quite understand why the threading lib depends on TLS. I am only including the threading lib to write thread handling and don't want or need security aspects (I'm handling those specifically myself for a custom app). I ultimately need to bundle all of it into a *very* small DLL (or shared lib on Linux) of my own and don't want to require a separate boost DLL. Why would you tie the two together, they seem completely orthoganal. BTW: I have found it rather easy to have Jam build both. I guess it is just more headache from a testing standpoint. I appreciate the info.

Testing and development. I compile against 5 compilers, and with both static and dynamic libraries this means compiling 10 variants at a minimum (through in both debug and release and you have 20 variants), which is time consuming. But the real kicker is that boost::thread itself is going to rely on TLS shortly, making it so you'll always need a DLL on the Windows platforms. William E. Kempf wekempf@cox.net
