Re: Missing TR1 cmath functions

#include <tr1/cmath>

leads to:

t.cpp: In function 'int main()':
t.cpp:5: error: 'tgamma' is not a member of 'std::tr1'
I suspect this may be because you are running (recent) darwin: in that case the llrint and llround functions may be unavailable, and _GLIBCXX_USE_C99_MATH_TR1 remains undefined....
