[sage-support] problems with mpir in upgrading to Sage 5.9
Sage complains with when building the package mpir-2.6.0.p2. I broswed through the logs and it looks like complains about the complier which the one my sage using is gcc-4.6.3 (I think). I think it might be a similar to the one that I had in upgrading to sage 5.7: http://trac.sagemath.org/sage_trac/ticket/14201 So I tried sage -f gcc-4.7.2.p1.spkg. Resulted also in an error: checking for gcc... gcc checking for C compiler default output file name... configure: error: in `/home/pong/sage-current/spkg/build/gcc-4.7.2.p1/gcc-build': configure: error: C compiler cannot create executables See `config.log' for more details. Looks like I can't fix this again, so hopefully someone can help me out here. I attached the two log files.

[sage-support] Conversion of DifferentialForm to a Symbolic form
Sage 5.4.1 running under Oracle VM on Windows 8.
Hi, I got the following code that does total differentiation off a Sage blog:
x, y, z = var('x, y, z')
U = CoordinatePatch((x, y, z))
F = DifferentialForms(U)
f = F(x^2 + y + sin(z)); f
g = f.diff(); g
cos(z)*dz + 2*x*dx + dy
How do I convert g to a symbolic form where dx, dy, and dz are also symbolic
variables? I need to assign values to all variables via a for loop. Also, is
it possible for g to be a 3x3 symbolic matrix? Thanks much, mahlon

[sage-support] Re: problem with gurobi backend in Sage 5.9 under Mac OS X 10.6.8
Gloops ! You are right ! Gurobi is built if the two files exist, and the first of those is : SAGE_INC + "gurobi_c.h" Looks like the value of SAGE_INC changed and does not end with a '/' anymore. A patch fixes that. Very short patch, by the way :-) http://trac.sagemath.org/sage_trac/ticket/14531 In the meantime, you can either apply the patch or. Create a symbolic link toward gurobi_c.h whose name is not "include/gurobi_c.h" but "includegurobi_c.h". Should work too :-D Nathann -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Installing gurobi works fine in Sage-5.8 also. So the problem first
appeared in Sage-5.9.
