[Insight-users] compile problem on OpenBSD

[Luis Ibanez]

Hi Amit,

The error in line 233:

#elif !defined(VNL_HAS_NO_FINITE)
//: Return true if x is inf
bool vnl_math_isinf(float x) { return !finitef(x) && !isnan(x); }
<<<<---233
//: Return true if x is inf
bool vnl_math_isinf(double x) { return !finite(x) && !isnan(x); }
//: Return true if x is inf
bool vnl_math_isinf(long double x) { return !finitel(x) && !isnan(x); }
#else


seems to be related to the symbol VNL_HAS_NO_FINITE
that is defined in line

#else
# warning finite() is not declared on this platform
# define VNL_HAS_NO_FINITE
#endif

at then of a cascade of platforms, that include
Borland, SysV, HPUX....

I would suspect that you should insert another
case there, in order to address the specific
features of FreeBSD.


If you find it,  please let us know, so we can
fix the version in the repository as well.


     Thanks,


          Luis
