Hi Tobi,
Thanks. I'll try and get this worked out. It seems that the new version
of ruby on Windows has been compiled with Mingw32 instead of Microsoft
Visual C++. To get the Ruby binding for Ruby v1.9.1 compiled for rrdtool
in Windows, it seems that I need to compile rrdtool with MinGW32.
I'll let let you know of the progess.
Thanks.
Cheers, Barrie

Hi Tobi,
Thanks for your reply. I did look at the config.log, but I wasn't able to
identify the exact problem. My assumption is one of the header files and
libraries are missing, but I'm not sure what to do next. I am currently
looking through the MinGW32 lists to see if I can find any hints to help.
I have attached a zipped copy of config.log. If someone has time I would
appreciate some help to learn.
Hi Barrie, from looking at config.log it seems that none of the
methods available to configure work ... most run into trouble
because the fpclass function is unknown ... what it comes down to,
is that you have to figure a way to make the following program
work:
#include <stdio.h>
int main(void){
double rrdnan,rrdinf,rrdc,rrdzero;
;
/* some math to see if we get a floating point exception */
rrdzero=sin(0.0); /* don't let the compiler optimize us away */
rrdnan=0.0/rrdzero; /* especially here */
rrdinf=1.0/rrdzero; /* and here. I want to know if it can do the magic */
/* at run time without sig fpe */
rrdc = rrdinf + rrdnan;
rrdc = rrdinf / rrdnan;
if (! isnan(rrdnan)) {printf ("not isnan(NaN) ... "); return 1;}
if (rrdnan == rrdnan) {printf ("nan == nan ... "); return 1;}
if (! isinf(rrdinf)) {printf ("not isinf(oo) ... "); return 1;}
if (! isinf(-rrdinf)) {printf ("not isinf(-oo) ... "); return 1;}
if (! rrdinf > 0) {printf ("not inf > 0 ... "); return 1;}
if (! -rrdinf < 0) {printf ("not -inf < 0 ... "); return 1;}
return 0;
}

Hi,
I am trying to compile rrdtool-1.3.99909060808 on Windows XP with
MinGW32. I have been able to get to the point below with both v1.3.8 and
v1.3.99909060808. I have been able to compile and run v1.3.8 compiled
with Microsoft VC++ 2008, so I assume there must be a way around this
error. The MinGW32 version I am running is gcc version 3.4.5
(mingw-vista special r3).
I'm not sure what to do next. Any suggestions?

you should do as the error suggests ... look at config.log it will
