errors

[VVE]

Hi,
Compiling this project in Visual Studio 2015, I got an error message:
3>C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\math.h(520): error C2059: syntax error: (
In math.h(520) I see:
Check_return _ACRTIMP double __cdecl rint(In double _X);
What should I fix? I try to use suitesparse-metis-for-windows for ceres-solver

Hi @VVE,

Check this issue: #23

A short fix is to add a check of the Visual Studio version in metis\GKlib\gk_arch.h:

#ifdef __MSC__
#if (_MSC_VER < 1800)
/* MSC does not have rint() function */
#define rint(x) ((int)((x)+0.5))
#endif
//....

rint() is available from Visual Studio 2013 (_MSC_VER 1800)

Thanks, i rather commented the #define rint(x) ((int)((x)+0.5)) in maths.h.
In math.h #define for rint() is declared without any Visual Studio version check.

good lord, why is metis' build system so janky... I'm hoping that this is the only magic I need to get over this hurdle for a METIS build myself... Thanks for providing this fix.
