minimal sample code

To test.
% gcc zzz.c -l rrd
% ./a.out /tmp/z.rrd --step 300 DS:in0:GAUGE:1500:-25:25 \
RRA:AVERAGE:0.5:1:1200 RRA:MIN:0.5:12:2400 \
RRA:MAX:0.5:12:2400 RRA:AVERAGE:0.5:12:2400

and, next failes too.

% rrdtool create --step 300 DS:in0:GAUGE:1500:-25:25 \
RRA:AVERAGE:0.5:1:1200 RRA:MIN:0.5:12:2400 \
RRA:MAX:0.5:12:2400 RRA:AVERAGE:0.5:12:2400

oops. It needs target filename.
% rrdtool create /tmp/test.rrd --step ....

I found rrdtools-1.2.9 fixed this problem.

[Comment 5 Daniel Webert 2005-06-03 15:54:22 UTC]

can we close this one? a tcl issue was fixed 18-may-05 says changelog and there
is no prob w/ 1.2.9

[Comment 6 TAKAHASHI, Hideaki 2005-06-06 05:42:47 UTC]

ok. rrdtool-1.2.9 seems good.

[Comment 7 Marcelo Goes (RETIRED) 2005-06-18 19:06:49 UTC]

I took 1.2.8 out for a different bug, so it should be good for this one too.
I see the patch suggested by Takahashi is included in 1.2.10, so I think we are
done with this issue.

Thanks for reporting.
