The tarball actually extracted to the directory sage-4.8 (in one of my vague states I read from the installation instructions that uses the directory I quoted); I am not compiling as root. I downloaded the source again, checked the md5sum and am recompiling as I write this. You may hear no further faint cries for help.

Please inform me if I should post this reply on the forum. Well, the standard is to reply to the whole list. But as you can see, Google Groups is set up in such a way that when it actually sends mails out to members, they are sent with the Reply-To header set to the email address of the group, so while you thought you were replying directly to me, you in fact replied to the whole list :) > The command that I used was simply the standard compile command "make" > within the sage-x.y.z. directory.

Since you talked about compiling a "package", I thought you might have tried to install the package "extcode" manually into an already working copy of Sage - Sage has its own mini packages called SPKGs (Sage Packages - creative, I know), and extcode is one of them. I thought this was unlikely, though, because extcode is one of the standard ones that is usually installed when you make Sage as a whole in the first place. So I was right, you are actually building Sage from scratch, not simply compiling that one package. > Upon reflection, I think the first thing I should do rather than waste > somebody's time further is to download the .tar file again and do an md5sum > on the tarball files, which I should have done in the first place.

But I also notice something interesting. You seem to be compiling in a directory called /usr/local/sage/sage-x.y.z./ - that's a little strange. Where did that directory come from? Where did you extract the tarball? There shouldn't be any directory inside it literally called "sage-x.y.z" - the wording in the installation guide is meant to imply that you will have a tarball called sage-4.8.tar , and it will contain a directory called sage-4.8 . Also, if you are trying to compile a copy of Sage directly in /usr/local (a location not usually writable by non-root users), you must be running as root, which is not recommended: > In fact, it is inadvisable to build Sage as root, as the root account > should only be used when absolutely necessary, as mis-typed commands > can have serious consequences if you are logged in as root. There has > been a bug reported in Sage which would have overwritten a system file > had the user been logged in as root. That's taken from the source installation documentation page. I suggest that if you really want sage to be in /usr/local instead of, say, in your homedir, that you instead create a user group called "sage" add yourself to the group, and then do `sudo chgrp sage /usr/local/sage` and `sudo chmod g+rwX /usr/local/sage`. Then you can run the compilation in /usr/local/sage even using your normal user account. -Keshav ---- Join us in #sagemath on irc.freenode.net ! -- 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 -- 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
