What compiler? Which boost? > /big_number/boost/multiprecision/mp_number.hpp:1730:11: error: ‘EOF’ was not declared in this scope EOF is an old-school macro defined in <stdio.h>. It must be in <cstdio> with C++11's C99 compatibility. > /big_number/boost/multiprecision/rational_adapter.hpp:208:45: error: expected ‘;’ at end of member declaration For some strange reason, the compiler does not like (min)() --- even with the well-known MSVC workaround of parentheses. > /big_number/boost/multiprecision/rational_adapter.hpp:208:47: error: ‘noexcept’ does not name a type It almost seems like you might have some macros activated when they shouldn't be. As far as I know, noexcept is C++11 and it only gets activated if BOOST_NO_NOEXCEPT is *not* defined. BOOST_NO_NOEXCEPT subsequently defines BOOST_MP_NOEXCEPT as nothing (empty), which is what you want. > My guess is that the EOF error may be a missing include, while the > latter two errors may be something that's missing in the relatively > old Boost installation on this test machine.  Can anyone suggest what I need to do? > Regards,  Phil. Just to move forward in the diagnosis, could you please perhaps try something? It's not the solution, but might show what's going on... Above the #include <boost/multiprecisioni/cpp_int.hpp> * #define EOF -1 * #define BOOST_NO_NOEXCEPT * #undef min * #undef maxMaybe this will shed more light on the exact situation at hand. Best regards, Chris.
