Yes pexpect. Same deal in sage-on-gentoo. I could add one of the patch from the current spkg on top of the latest version and it would work everywhere I could think of except the notebook. Plot would not be rendered. I don't remember trying with the new notebook. I would take slower too. On the

fakechroot is a LD_PRELOAD hack that overrides glibc calls and e.g. redirects file open() calls. Though its not perfect, for example no pseudo-ttys (I think this already rules out Sage). On Friday, December 21, 2012 6:19:48 PM UTC, mmarco wrote: > > I have seen that there is an android app that

I have seen that there is an android app that runs an ubuntu desktop without the need of root access. From the web page, i see that it uses something called fakechroot. I would like to investigate that possibility. Maybe it could be the open door to some nice android app that would install sage to

Dear all, I just remarked (painfully) that the optional GCC 4.7.2 spkg includes all of the GCC including gcj which depends on zip or jar for building. Is this really useful? As far as Sage development is concerned, I guess that gcc, g++ and gfortran are enough. That would make a smaller spkg wit
