sagemanifolds error

[aishen]

Hi,
I am on ubuntu 16.10 (16.04 +1), and I can't compile sage 7.2 (flint error)
Si I install ppa version 7.1 and 
sudo bash sm-install.sh everythink went well. Typing this in a console or in sage -n=jupyter get the following ?
Any help
Thanks
Henri

It seems you are running only the version of SageManifolds which is included in main Sage. For the time being, only topological manifold are implemented in this version, hence the error message. For instance, if you try
M = Manifold(4, 'M', structure='topological')
it should be OK.

Regarding the install of the full SageManifolds, are you sure you have run sm-install.sh from the Sage 7.2 root directory ?

Best wishes,

Eric.

It's getting worse... ppa sage is seg fault and I can't compile 7.2 because flint error, I wonder if I downgrade to 16.04 but I don't think that 's the problem.
At the moment I don't have sage any more. I purge all and I will try to restore that !
Thanks

I took the linux binary 16.04 and in local I bash sm-install
Everything is working fine now.
thanks
