That is the problem, as the file is 2.2GB. -rw--- 1 sage sage 2.2G 2007-11-07 09:52 Ubuntu.vmdk I think it's supposed to be easy (and sometimes very desirable) to convert a filesystem in Windows from FAT32 to NTFS. This will make the filesystem journaled, which means the person won't see the "checking the file system" blue screen whenever Windows crashes and reboots. That said -- vmware has an option to split virtual disks into files that are all < 2GB. I will definitely fix the vmware machine when i get back to Seattle to only include files that are < 2GB. However, this will have to wait about a week.

Hi, I've got extremely happy when I've found out about this cool project, it was time that some powerful 'mathematica-like' open source package would see the light :-) I've installed successfully SAGE on my linux machine in no time but now I'm trying to install it on windows for my students and I'm in deep trouble: 1. I can't unzip correctly sage-vmware-2.8.12.zip since when Ubuntu.vmdk it reaches 2147483 Kb the unzipping stops claiming that there's no more space on the HDD (yes, I checked and there's plenty of space on it :-) I tried with both unzip under linux and the m$ unzipper under winblow$ getting the very same negative results :-( 2. if I nevertheless try to run sage via vmware with the slightly shortened version of Ubuntu.vmdk then the vmware player complains about the size of it, claiming that it's bigger than 2Gb and that it does not like this at all. It is only me that found this odd behavior? Any hint would be very welcome!

[sage-support] Re: Does the Sage Python installation interfere with a current Python?
Hello Lou, All of Sage's Python stuff exists independently of the system-wide Python and shouldn't have any effect on it. In particular, if the $SAGE_ROOT directory is something like /Applications/sage, then Sage's Python will live under /Applications/sage/local. --Mike --~--~-~--~~~---~--~~ 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://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---
[sage-support] Does the Sage Python installation interfere with a current Python?
(I posted this on the discussion forum. I don't know which one is the right one to ask this on. Apologies if this is not the appropriate forum.) I am interested in trying Sage and have a question about the Python that comes with the Sage installation. If this is not the proper forum for this question, would someone please point me to one? Thanks. I currently use Python 2.4 and I am in the middle of a project that I don't want interrupted by dealing with a new installation and any problems that might come up (not uncommon). Does the Sage installation 'step on' or replace or in any way interfere with a currently installed Python and its site packages (e.g. NumPy)? I would hope that it can be done independently of the current installation. I use a Mac Book Pro and a Mac Pro, OS X 10.4.

That issue is described in trac ticket #975, but in your particular case even the work-around described there doesn't work. One way to fix this in your particular case is to write a small script that does "export LD_LIBRARY_PATH=" before starting emacs.

[sage-support] hg_sage.commit error
Hi: I am trying to create a patch for the permgp bug Carlo H reported last week. In 2.8.12, I (1) created a clone and added a few lines to permgp.py that seemed to fix the problem. (2) ran sage -b (no problems) (3) sage -t "path/permgp.py" (all tests passed) (4) typed export EDITOR=emacs, then started sage and typed: sage: hg_sage.commit() cd "/home/wdj/sagestuff/sage-2.8.7.rc1/devel/sage" && hg diff | less cd "/home/wdj/sagestuff/sage-2.8.7.rc1/devel/sage" && hg commit emacs: symbol lookup error: /usr/lib/libcairo.so.2: undefined symbol: FT_Library_SetLcdFilter transaction abort! rollback completed abort: edit failed: emacs exited with status 127 I also tried this with another editor (kate) with the same error. However, when I set export EDITOR=vi, everything worked fine. This is using ubuntu 7.10, 64 bit. Should I create a trac ticket for this or am I doing something wrong? - David Joyner --~--~-~--~~~---~--~~ 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://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---
