[sage-support] error in upgrading SAGE to version 4.8
I am trying to upgrade SAGE from 4.7.2 to 4.8 in my dept server by simply running ./sage --upgrade but ran into the following error: --- sage/matrix/matrix_cyclo_dense.pyx -- /opt/sage-current/local/lib/ python2.6/site-packages//sage/matrix/matrix_cyclo_dense.pyx python `which cython` --disable-function-redefinition --embed- positions --directive cdivision=True,autotestdict=False,fast_getattr=True -I/opt/sage- current/devel/sage-main -o sage/matrix/matrix_dense.c sage/matrix/ matrix_dense.pyx Error compiling Cython file: ... # allow lambda functions if self._nrows==0 or self._ncols==0: return self.__copy__() v = [z.derivative(var) for z in self.list()] if R is None: ^ sage/matrix/matrix_dense.pyx:428:13: local variable 'R' referenced before assignment Error running command, failed with status 256. sage: There was an error installing modified sage library code. There is a bunch of warnings about variables being referenced before assignment earlier but did not cause a crash. Any idea on how to fix this? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
Re: [sage-support] Re: Simplifying log expressions
Dear Sage Developers: There seems to be a similar issue in Sage Version 4.8: sage: a=log(6)/(1+log(2)) sage: (6*exp(-a)-2^a).full_simplify() -(2^(log(3)/(log(2) + 1) + 1/(log(2) + 1))*3^(1/(log(2) + 1))*e^(log(2)^2/(log(2) + 1)) - 6)/(2^(1/(log(2) + 1))*3^(1/(log(2) + 1))) sage: (6*exp(-a)/2^a).simplify_full() 2^(log(2/3)/(log(2) + 1))*3^(log(2)/(log(2) + 1))*e^(-log(2)^2/(log(2) + 1)) Sincerely, Greg Marks | Greg Marks | | Department of Mathematics and Computer Science | | St. Louis University | | St. Louis, MO 63103-2007 | | U.S.A. | || | Phone: (314)977-7206 | | Fax: (314)977-1452 | | Web: http://math.slu.edu/~marks| -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

If one uses Maxima on these expressions directly, it does not come up any better than that. (Or perhaps one needs to know more about Maxima than I do).

[sage-support] patch buildbot help
Hi all, I can't figure out how to get the patch buildbot to behave at ticket #10229. I want it to apply just the second of the two patches on Trac (the second supersedes the first), but it's applying the first, then the second--which then obviously fails. I read the instructions at http://wiki.sagemath.org/buildbot but can't figure out my error. I'd appreciate any pointers!
