Ok, thanks. I have it. After some fixing (change file extension from .cc to .cpp, change line endings from LF to CRLF, append one more directory to INCLUDE) I received following error: example.cpp(18) : error C3200: 'boost::math::pi_value<T>' : invalid template argument for template parameter 'F', expected a class template example.cpp(18) : see reference to class template instantiation 'boost::math::pi_value<T>' being compiled example.cpp(81) : fatal error C1903: unable to recover from previous error(s); stopping compilation I have stripped down problematic code to very simple: #include <iostream> template <template <typename> class F, typename T> struct constant_value { T operator()() const { return T(); } }; template <typename T> struct pi_value : constant_value <pi_value, T> {}; int main() { pi_value<double> t; std::cout << t(); } and tried it under Comeau (online), with no problems. It also compiles fine under GCC 3.3.1 (mingw). From my (limited) understanding of templates this code is fine, thus apparently there's problem with VC71. Looks like using template being just defined as template template parameter makes VC71 confused. I reported it to Microsoft (on its private newsgroup). B.
