[postgis-users] Compile problem on solaris11: Undefined symbol - isfinite

[Phillip Ross]

I don't know for sure if the standard C library on Solaris has the
"isfinite" macro or not.  When I grepped around header files on solaris, I
found the following references (though I don't know if they're relevant or
not):

gcc/4.5/include/c++/4.5.2/tr1_impl/cmath:  using std::isfinite;
gcc/4.5/include/c++/4.5.2/cmath:#undef isfinite
gcc/4.5/include/c++/4.5.2/cmath:    isfinite(_Tp __f)
gcc/4.5/include/c++/4.5.2/cmath:      return
__builtin_isfinite(__type(__f));

include/iso/math_c99.h:#undef   isfinite
include/iso/math_c99.h:#define  isfinite(x)     __extension__( \
include/iso/math_c99.h:                 { __typeof(x) __x_r = (x);
isfinite(__x_r) && \
include/iso/math_c99.h:#undef   isfinite
include/iso/math_c99.h:#define  isfinite(x)     __builtin_isfinite(x)

And if I query the manpages I find the following (and I hope I'm not
violating any ORCL copyright agreements by pasting this:

Mathematical Library Functions                       isfinite(3M)
NAME
     isfinite - test for finite value
SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include <math.h>
     int isfinite(real-floating x);
DESCRIPTION
     The isfinite() macro determines whether its argument  has  a
     finite  value  (zero, subnormal, or normal, and not infinite
     or NaN). First, an argument represented in  a  format  wider
     than  its  semantic  type is converted to its semantic type.
     Then determination is based on the type of the argument.
RETURN VALUES
     The isfinite() macro returns a non-zero value if and only if
     its argument has a finite value.

And also... GEOS does compile, and I'm using geos 3.4.2 for this.

Thanks for your continued help!
