I added the matroids (I think this one worked) by using 'sage -hg > clone https://bitbucket.org/matroid/sage_matroids' and '../sage setup.py > install' from the shell prompt, but got the following errors on the second > command: > > Error compiling Cython file: > ------------------------------------------------------------ > ... > versionB = 0 > size = 0 > limbs = 0 > longsize = 0 > for i from 0 <= i < self.nrows(): > versionB, size, limbs, longsize, data = > bitset_pickle(self._M[i]) > ^ > ------------------------------------------------------------ > These errors are because we moved some code out of our codebase and directly into Sage. I think this is the easiest way to get matroids to work right now:
0) From a terminal shell, run /path/to/sage -clone mymatroid (this will ensure the "main" branch of sage stays untouched, see http://www.sagemath.org/doc/developer/walk_through.html#creating-a-sandbox ) 1) Download the .patch files from each of the following pages: http://trac.sagemath.org/sage_trac/ticket/14668 http://trac.sagemath.org/sage_trac/ticket/7477 (only the two mentioned in the description). 2) Start Sage from the directory to which you saved the patches, and issue these commands: sage: hg_sage.apply("trac_14668_bitsets.patch") sage: hg_sage.apply("trac_7477_setup_doc_load.patch") sage: hg_sage.apply("trac_7477_code.patch") Watch for any errors. 3) Quit Sage, run /path/to/sage -b 4) Enjoy! > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
