[sage-support] Mercurial problems in 3.1.2
Hi, all, I'm on Mac OS X, 10.5.4 (dual quad xeon), and when I run sage -hg commit, I get this dyld: Symbol not found: __cg_png_create_info_struct Referenced from: /System/Library/Frameworks/ ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/ Versions/A/ImageIO Expected in: /SandBox/Justin/sb/sage-3.1.2/local/lib//libPng.dylib transaction abort! rollback completed abort: edit failed: emacs killed by signal 5 Running emacs by itself works, but I get the same as above if I first run . sage-env in the same window. I haven't figured out exactly what the error is yet (the symbol lodging the compaint doesn't appear in either library), but this is odd: There are symlinks libpng.dylib - libpng12.dylib - libpng12.0.22.0.dylib libpng12.0.dylib - libpng12.0.22.0.dylib and this: $ otool -L libpng12.0.22.0.dylib libpng12.0.22.0.dylib: /SandBox/Justin/sb/sage-3.1.2/local/lib/libpng12.0.dylib (compatibility version 23.0.0, current version 23.0.0) /SandBox/Justin/sb/sage-3.1.2/local/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.1) which to me makes libpng12.0.22.0.dylib dependent on libpng12.0.22.0.dylib!!

This is the same crap issue you hit when building 3.1.2.rc-something, i.e. emacs is linked against Apple's libnpng while launching it from hg causes it to pick up out linpng. Results in *boom*. You can work around this by writing an emacs script in SAGE_LOCAL/bin that sets DYLD_LIBRARY_PATH to the old DYLD_LIBRARY_PATH and then launches emacs. Is someone can find out where Apple has its modifications to libpng this issue can be resolved. Justin Cheers, Michael -- Justin C.

Hard to say where they keep it, but they (Apple) appear to be using 1.2.24, while we (Sage) appear to be using 1.2.22 (assuming these are version numbers). Might that be the cause? I'll see if I can find out where the source is; if Apple made changes, they should be available (ether directly from Apple, or from upstream - assuming the license requires this, of course. Does it?). It's bedtime for me; early class field theory tomorrow. Thanks for the response. Justin -- Justin C.

[sage-support] Sage Days 10: October 10-15, Nancy, France
Hi all, this is a reminder that Sage Days 10 (SD10) is fast approaching! It is still possible to register until October 3. See http://wiki.sagemath.org/days10, where you can see the scientific program, with the titles and abstracts of the invited and contributed talks. After SD6 in Bristol last year, SD10 will be the 2nd Sage Days in Europe, and a unique opportunity to discuss with the Sage developers. Two extra special events are planned for SD10: * on October 11, there will be a sage-combinat session: The purpose of the *-Combinat project is to provide an extensible toolbox for computer exploration in algebraic combinatorics, and foster code sharing between researchers in this area. We will present the history, features, and design of MuPAD-Combinat, and discuss the timeline, difficulties, but also great technical and community opportunities that arise from the ongoing port as Sage-Combinat. * on October 14, Robert Bradshaw will give a plenary demonstration of Sage. If you have any questions, feel free to email me or any of the other organizers! On behalf of the organizing committee, Paul Zimmermann PS: I take the opportunity to advertize a workshop on integer factoring that will take place just before SD10 in Nancy: cado.gforge.inria.fr/workshop/. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Printing: At the moment the Print link prints all source code and output. It would be nice to be able to print just the code or just the output. 2. When I open an existing worksheet, not all cells are evaluated. Especially ones that start with %hide or %latex don't show the output until I choose Evaluate All from the Actions...-menu. It would be nice to have ALL cells evaluated automatically when starting up a worksheet. Great work so far, I'm really impressed with how quickly Sage is developing!

[sage-support] problems with install path
L.S., When updating to Sage 3.1.2 I run into the following problem: Am using a Mac G4 dual core, OSX 10.4.11. Used a previous version of Sage without apparent problems.

When I get to 10x10 is runs for a while the crashes with: Unhandled SIGSEGV: A segmentation fault occured in SAGE. This probably occured because a *compiled* component of SAGE has a bug in it (typically accessing invalid memory) or is not properly wrapped with _sig_on, _sig_off. You might want to run SAGE under gdb with 'sage -gdb' to debug this. SAGE will now terminate (sorry). I'll try to reproduce the crash and see what I can do about it.

[sage-support] long arithmetic
Using Sage I solved a long list of equations and put the solutions (s) in a list; e.g.: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) (q,j,k,s) : ([52, 30, 2081203288L], 52, 30, 2081203288L) ([53, 53, 17903198518682712L], 53, 53, 17903198518682712L) Now I want to plug j and s into the list of y equations so that I can do further calculations involving i. But Sage appears to be getting hung on the s being long: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) y = 2*(2**k)*i + s (j,k,s,y) : ... ... TypeError: unsupported operand parent(s) for '+': 'Symbolic Ring' and 'type 'long'' When I take the s out of the equation for y it's OK: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) y = 2*(2**k)*i (j,k,s,y) : (52, 30, 2081203288L, 2147483648*i) (53, 53, 17903198518682712L, 18014398509481984*i) FWIW: sage: type(j), type(k), type(s), type(y), type(i) (type 'int', type 'int', type 'long', class 'sage.calculus.calculus.SymbolicArithmetic', class 'sage.calculus.calculus.SymbolicVariable') None of the tricks I tried have convinced Sage and y that s is OK. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Sage editor
I run Sage on my Mac rather than on the web. I often bring up the previous command and edit it then rerun it. The editor is very tedious in that the only way I have figured out how to move the cursor around in the text is one character at a time using the left and right arrow keys and the back-space-delete key. Given a several-line for-loop to edit this can be frustrating. Am I missing something obvious to everyone else? Is this a feature of the Mac rather than Sage? A less-than-satisfactory work-around is to copy/paste to a programmer's editor, do the change, then copy/paste back to Sage. Which leads me to another and related question. Are the editing capabilities of Sage when used with cells (as described in some of the Sage ref's) on a web server significantly better? If so would I be well advised to install web server software on my Mac and use Sage that way? (I don't have 24x7 fast web access...) Is that installation process complicated?

I'd experiment to find the meta key if you'd just ship me a mac :). I'd even try to figure out how to configure the meta key to be whatever you wanted.

I should add that this is the approach on 10.5. For earlier releases, check for settings or Get Info in the menus, and that should lead you to a similar choice for option as meta. I don't recall when this capability was added, but I think it predates the earliest Mac OS X release we support. Justin -- Justin C.

I'll guess that it's a difference between versions (1.2.22 vs.
1.2.24), but I can't find old source on the libpng site, and it
doesn't show up on the Darwin site (which I infer means that they did
not change anything). I'll poke further, but if anyone has a better
idea, speak up!

I am playing with libpng-1.2.32 since that is the latest release and
also has a boatload of security updates since the lowly 1.2.22 that we
ship. Hopefully this will resolve the symbol missing issues. I am
testing 3.1.3.alpha0 on OSX 10.5 to see if I can hit any of those
problems.
