[IMP-dev] Compiling error in double precision.

[Seung Joong Kim <>]

Hi, I got a following error message, when I try to use a double precision. 
(I'm using "typedef double Float;" in base_types.h)


modules/core/src/internal/ParticleGrid.cpp: In member function 'void 
IMP::core::internal::ParticleGrid::build_grid(const IMP::Particles&)':
modules/core/src/internal/ParticleGrid.cpp:57: error: ISO C++ says that 
these are ambiguous, even though the worst conversion for the first is 
better than the worst conversion for the second:
/usr/include/architecture/i386/math.h:352: note: candidate 1: double 
pow(double, double)
/usr/include/c++/4.0.0/cmath:344: note: candidate 2: float 
std::pow(float, float)
scons: *** [modules/core/src/internal/ParticleGrid.os] Error 1
build/include/IMP/SingletonContainer.h:59: Warning(473): Returning a 
pointer or reference in a director method is not recommended.


Could you take a look at it?
