#51: M_PI definition not always available to wavetoy-loopcontrol.c -------------------------------------------+-------------------------------- Reporter: richard.oshaughnessy@… | Type: defect Status: new | Priority: minor Milestone: | Component: Cactus Version: ET_2010_06 | Keywords: c99 -------------------------------------------+-------------------------------- In certain situations, I've hit the following error

/home/oshaughn/Numerical/EinsteinToolkit/Cactus/arrangements/Carpet/LoopControl/src /wavetoy-loopcontrol.c:183: error: 'M_PI' undeclared (first use in this function)

Per Frank: "it is probably finding math.h, but M_PI is not declared in that file, at least not from C99 on (it was before). It's strange that nobody found that before, C99 should be standard with Cactus nowadays."
