Hi Tobi,
I'm working with rrdtool-1.3.99909082100 now. I added the change noted
below and that works OK. The configure script now makes it through the
IEEE math test.
The next failure is at the ctime_r test. ctime_r for win32 is included
in win32comp.c in the src directory. I'm working on how configure can
access that function.
Cheers, Barrie

Hi BenBE,
Thanks for the help. I didn't see your post come in, sorry for the late reply.
It uses the Solaris 10 branch, even though it should use none of them???
I see the problem now. Just need to work out how to fix it. This is proving to
be a good learning exercise. :-)
/* solaris 10 it defines isnan such that only forte can compile it ... bad bad
*/
#if (defined(HAVE_ISNAN) && defined(isnan) && defined(HAVE_FPCLASS))
# undef isnan
# define isnan(a) (fpclass(a) == FP_SNAN || fpclass(a) == FP_QNAN)
#endif
Thanks.
note that the way configure works is by trying many things out and
when the fail going on to the next one ... it will take the one
which works ...
have a look at configure.ac and m4/acinclude.m4 how this is done
...
in any event, to code above could be fixed like this:
#if (defined(HAVE_ISNAN) && defined(isnan) && defined(HAVE_FPCLASS) && defined(FP_SNAN)
&& defined(FP_QNAN))
# undef isnan
# define isnan(a) (fpclass(a) == FP_SNAN || fpclass(a) == FP_QNAN)
#endif
I have updated the trunk ... tomorrows snapshot will contain the
change ...
cheers
