[Insight-developers] ITK 3.14 cannot build with GCC on non-ix86 (due to Rounding code) vnl_math_rnd_halfinttoeven

[Tom Vercauteren]

Hi Luis,

VNL_CHECK_FPU_ROUNDING_MODE should not be the culprit here. This
variable is only meant to perform some debugging.

What must be wrongly defined is
  GCC_USE_FAST_IMPL

As I mentioned earlier, this might have been corrected already in the HEAD:
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.h?root=Insight&r1=1.13&r2=1.11&sortby=date
