I've linked librrd statically for that "rrdtool-ppc32" binary (look at ldd and the binary size, compared to a purely dynamically linked version). As i already sent you in private, the one box looks quite suspicious, given that it's RPM database seems to be corrupted, i.e. i wouldn't be convincend anymore that updates work like you'd expect. In general, a box with a broken RPM databse is doomed, in my experience. In my POV trunk is fine on PPC with 32bit (I've even did some cursory checks on an ia64 box to see if there are any unexpected problems on 64bit setups, and all is well) and any other arch for that matter. Check you setup.. HTH, _______________________________________________ rrd-developers mailing list rrd-developers@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-developers
