Hi,
For installing Sage 6.4 from sources on Ubuntu 14.04, I suggest that the package
libssl-dev is added to the prerequisites listed in
http://www.sagemath.org/doc/installation/source.html#prerequisitesand in SAGE_ROOT/README.txt
Indeed, without it, the command ./sage --notebook=ipython terminates by
ImportError: No module named _ssl
With libssl-dev, the ipython notebook works well.
For a binary install, I've tried sage-6.4-x86_64-Linux-Ubuntu_10.04_x86_64.tar since the Ubuntu 14.04 LTS is not on the mirrors yet (I understand from a previous message on this list that there is some built problem for 14.04 LTS). Then the command ./sage --notebook=ipython terminates by
ImportError: libssl.so.0.9.8: cannot open shared object file: No such file or directory
Indeed, on Ubuntu 14.04, the libssl.so version is 1.0.0, not 0.9.8. I guess this issue will be resolved as soon as Ubuntu 14.04 LTS binaries are available.
Two unrelated remarks:
- On
http://sagemath.org/, clicking on "Changelog" below "Download 6.4" leads to a broken page
- On
http://sagemath.org/download-linux.html, there is no longer the mirror in Paris 6 University.
Best wishes,
Eric.
