Hello, as far as I can tell these are symbols from the termcap library. Sorry, I should have written curses/ncurses library - too early for me. Could you post the exact command of the compiler/linker before the failure? There have been several efforts to get SAGE to build and run on

Hi, Thanks for taking the time to make up this example. I think it is good to put it in the documentation. Yes you can break factorcaching (with auto_reduce=False) the way you do it. ***But*** let me point out that by rewriting your example only slightly it becomes *much* faster than the

There is also Yafray. It is used as one of the rendering engines by blender and seems to be very good. Look here http://www.blender.org/features-gallery/gallery/images/ and scroll down a bit to External renderers. I *think* Yafray only has meshes so sage would have to create the geometric

Some variant of this is definitely worth thinking about much more, since it is one of the standard models for open source software (which is now tried and tested, and does work if one is providing a genuinely useful service). For example, we could officially sell support for SAGE at the

The problem doesn't seem to be with libtermcap or curses. It's a flag problem. When compiling libsingular, the --shared flag has to be passed to gcc, instead of the default -export-dynamic. For that, the Makefile in Singular/Makefile has to have a secial section for nexentaos as follows: {{{ ifeq

Hi Everyone, The main crypto functionality that I implemented concerns classical cryptography, for the purposes of teaching: http://echidna.maths.usyd.edu.au/~kohel/tch/Crypto/ Hence most of the systems are breakable (using suitable classical cryptanalytic attacks). The cryptosystem class can
