[Slackbuilds-users] Sage build fail

Sun Mar 26 16:17:42 UTC 2017

I have tried to build the latest version of Sage (7.5.1) with sbopkg in two
Slackware64 14.2 systems; they are both 64-bit systems, one of them
vanilla, the other multilib. I get exactly the same error trace in both.
The first line seem to suggest that the system ran out of memory, but one
of them comes with 3 GB of RAM, and the other with 8 GB of RAM (the
multilib system). The traces are extremely long; I am enclosing the last
few lines alone. The trouble seems to be always in the plot3d module.
