I'm getting compile errors when including "boost/math/special_functions/zeta.hpp" (which in turn is included indirectly by "boost/random.hpp"). This is in the recently released "boost_1_54_0.tar.bz2" under Linux Mint 16 for amd64, gcc 4.7.3. Minimal test case: #include "boost/math/special_functions/zeta.hpp" int main() {} Exact error message: In file included from source/eldwood/test/zeta.cpp:1:0: intermediate/usr_x86_64-pc-linux-gnu/include/boost/math/special_functions/zeta.hpp: In function ‘T boost::math::detail::zeta_imp(T, T, const Policy&, const Tag&)’: intermediate/usr_x86_64-pc-linux-gnu/include/boost/math/special_functions/zeta.hpp:877:24: error: ‘log_root_two_pi’ is not a member of ‘boost::math::constants’ intermediate/usr_x86_64-pc-linux-gnu/include/boost/math/special_functions/zeta.hpp:877:52: error: expected primary-expression before ‘,’ token intermediate/usr_x86_64-pc-linux-gnu/include/boost/math/special_functions/zeta.hpp:877:60: error: expected primary-expression before ‘>’ token intermediate/usr_x86_64-pc-linux-gnu/include/boost/math/special_functions/zeta.hpp:877:62: error: expected primary-expression before ‘)’ token The same error also manifests under clang. -- Rainer Deyke (rainerd@eldwood.com)
