Hi,
It cannot configure rrdtool-1.2.10 on Solaris 9 with gcc-4.0.0 or
later. the error message is following.
checking for isinf... no
checking for isinf with <math.h>... yes
checking if IEEE math works out of the box... no
checking if IEEE math works with the -ieee switch... no
checking if IEEE math works with the -qfloat=nofold switch... no

configure: error:
Your Compiler does not do propper IEEE math ... Please find out how to
make IEEE math work with your compiler and let me know ([EMAIL PROTECTED]).
Check config.log to see what went wrong ...
The configure script checks isinf with <math.h> as following.
#include <math.h>
int
main ()
{
float f = 0.0; isinf(f)
;
return 0;
}
Gcc-4.0.0 or later eliminates calls to pure functions whose return
value is not used.[1] So compilation of the above code is succeed and
the HAVE_ISINF macro is defined if the system does not have isinf().
Therefore, the following isinf(a) macro is not defined.
/* Solaris */
#if (! defined(HAVE_ISINF) && defined(HAVE_FPCLASS))
# define HAVE_ISINF 1
# define isinf(a) (fpclass(a) == FP_NINF || fpclass(a) == FP_PINF)
#endif
Jakub Jelinek suggested the solution in [email protected] list.[2] Could
anyone take look it?
