Hi, As discussed in https://groups.google.com/d/msg/sage-release/yzb7O3o-kNQ/dSbHre1yBQAJ the current Sage 6.10 binary for Ubuntu 15.10 suffers from the fact that the file SageMath/local/lib64/libstdc++.so.6 mismatches the system version of libstdc++.so.6 (6.0.20 against 6.0.21).
The consequences of this are pretty severe: 1/ ./sage -n jupyter fails to open a notebook in the browser 2/ no plot is produced from sage terminal, e.g. sage: plot(sin(x), 0, 1) fails silently ! Since Ubuntu 15.10 is the latest version of the most popular Linux distribution, more and more users start to complain: see these posts: https://groups.google.com/d/msg/sage-support/yAsyKA-pA4M/GCExP7VACgAJ http://ask.sagemath.org/question/32151/how-to-produce-graphics-from-cli/ I've prepared a fix, in the form of a new version of the file sage-6.10-Ubuntu_15.10-x86_64.tar.bz2, which can be downloaded from https://upload.obspm.fr/get?k=2FUh4BTyHprQk8jTfrS md5sum: f3cdb32bc5438ded8590c3c8cce9e716 The above tar file differs from the original one by only a change in one symlink: SageMath/local/lib64/libstdc++.so.6 -> /usr/lib/x86_64-linux-gnu/libstdc++.so.6 instead of SageMath/local/lib64/libstdc++.so.6 -> SageMath/local/lib64/libstdc++.so.6.0.20 This is the solution suggested by Robert Samal in https://groups.google.com/d/msg/sage-support/yAsyKA-pA4M/iwWRRS9KCgAJ I've tested the new tar file and it works well on my Ubuntu 15.10 computer. Since /usr/lib/x86_64-linux-gnu/libstdc++.so.6 is part of the basic install of Ubuntu 15.10 (i.e. g++ is installed by default), I think this should work for any user. So, could you please replace the tar.bz2 file on the servers by the above one ? Best wishes, Eric. -- You received this message because you are subscribed to the Google Groups "sage-release" group.
