[rrd-users] configure problem

[Rob Hawkes]

The configure script says my compiler cannot do IEEE math.

wallaby> uname -a
SunOS wallaby 5.7 Generic_106541-06 sun4u sparc SUNW,Ultra-5_10

wallaby> gcc -v
Reading specs from

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 at ee.ethz.ch).
Check config.log to see what went wrong ... 

Tried adding -ffloat-store to the CFLAGS in configure, but the test
still fails.  I would appreciate any help.  Thanks.
