[rrd-users] sunstudio11 rrdtool-1.2.19/solaris10 build: ieee error

[Dirk Vleugels]

Hi,

im trying to build rrdtool-1.2.19 using sunstudio11 on a t2000 running
solaris10. The flags used are:

-xO4 -fast -xarch=v8 (i need 32bit binaries). config yielded:

IEEE Math Checks
checking for fpclassify... no
checking for fpclassify with <math.h>... yes
checking for finite... yes
checking for isinf... no
checking for isinf with <math.h>... yes
checking if IEEE math works out of the box... not isnan(NaN) ... no
checking if IEEE math works with the -ieee switch... no
checking if IEEE math works with the -qfloat=nofold switch... no
checking if IEEE math works with the -w -qflttrap=enable:zerodivide... no

checking if IEEE math works with the -OPT:IEEE_comparisons=ON switch... no
checking if IEEE math works with fpsetmask(0)... not isnan(NaN) ... no
checking if IEEE math works with signal(SIGFPE,SIG_IGN)... not isnan(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 (tobi at oetiker.ch).
Check config.log to see what went wrong ...

Using -fround=tozero -xlibmieee to CC didn't change anything.

I can provide the config.log if needed.

Any clues?

Regards,
Dirk
