Hello Sage 4.8 came with an earlier Cbc package, 2.3-somethingorother. It included something called OsiVol. Your version of sage is trying to build with that library. The more recent Cbc package, 2.7.5, does not. It looks as if sage downloaded the newer Cbc package. An unpatched sage 4.8 does not know how to build that version of Cbc. Hence, your errors.
I THINK that ticket #12220 would fix it, if you could install it; I've been running Cbc-2.7.5 on several patched versions of 4.8. But, I'm not sure you can install that patch in the state your system is in, now. It should work fine with sage 5.0. Nathann Cohen might have a better insight on what's causing this problem. john perry -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
