Your Compiler does not do propper IEEE math

 

Vil kompilere rrdtool på min via c3 boks (ezra core), installeret med
Gentoo 1.4rc1 (gcc-3.2) og jeg får så denne fejlmeddelelse (som jeg har
mailet til tobias oetiker også):

checking for fpclassify with <math.h>... no
checking for finite... yes
checking for isinf... yes
checking if realloc can deal with NULL... yes
checking if IEEE math works out of the box... nan == nan ... no
checking if IEEE math works with the -ieee switch... no
checking if IEEE math works with the -qfloat=nofold switch... nan == nan
... no checking if IEEE math works with the -w
-qflttrap=enable:zerodivide... nan == nan ... no checking if IEEE math
works with the -mieee switch... no checking if IEEE math works with the
-q float=rndsngl switch... no checking if IEEE math works with the
-OPT:IEEE_comparisons=ON switch... no checking if IEEE math works with
fpsetmask(0)... no checking if IEEE math works with
signal(SIGFPE,SIG_IGN)... nan == nan ... 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
(oetiker@xxxxxxxxxx). Check config.log to see what went wrong ...

Sig til hvis i har nogle løsningsforeslag :-)
