OK guys so to be more specific, I had my problem when i wanted to make an install with downloading the .app.dmg file i deleted that install, and reinstalled with the .dmg file only i do get a terminal opened when double clicking on the sage icon, i typed in notebook() and Sage DOES open in Chrome, its working fine so, problem solved to me doing the installation without the app.dmg file. I leave it to the devs to figure out why this install works and not the other one...

Do you have SAGE_ROOT set permanently to Users/echolalie/Desktop/Sage-6.9.app for some reason? E.g. ~/.bashrc ~/.bash_profile, ..., Also, the "-bash: PS1: command not found" is suspicious. Not a Sage problem, but most likely an issue with your init files. What is $PS1?

[sage-support] Re: Installation problem
I faced the same problem when installing sage on a different computer and then copying my .sage folder from my original computer across. First I had a permission problem and when fixing this by chown -R newuser .sage, I got the Errno 39 as above. I found out that some symlinks didn't copy across (even when using rsync with pretty much preserve everything...), causing the Errno 39. These symlinks reside in .sage/sage_notebook.sagenb/home/ and after copying them over manually, the notebook starts again. I hope someone can give advice on how to properly migrate the .sage folder to a new computer properly without manual interaction.

[sage-support] Re: installation problem
The 'readline hell' part is an annoying openSUSE problem. If you see the file spkg-install of the package readline, you will find that there is a provision for trying to recognize the system's readline package. But this is only useful for some versions of openSUSE. For example readline in sage-4.5.2 only recognizes openSUSE 11.1. Likewise sage-4.5.3 might not recognize your SUSE distribution. You'll have to create a small workaround --- much in the same way as the creators of the spkg-install file did.

Your error message looks exactly like the one reported here a few
months ago:
http://groups.google.com/group/sage-support/browse_thread/thread/aba48495d9c09e03/f25d062b6764492f
In that case it was somehow caused by an upgrade after installing the
binary. One option would be to install a source version.

Re: [sage-support] Re: installation problem
Thanks for this Marshall.
I did try to compile my own, but ran in to utter dependency hell.
In the end I managed to get it to work by deleting some of the
readline libraries, but I don't understand why that worked.
Would you say that the google groups you point me towards
is a more active forum than the sage-support mailing list?
Thanks again

After doing tar zxvf sage-2.8.2-debian64-x86_64-Linux.tar.gz, I changed to the sage-2.8.2-debian64-x86_64-Linux directory and did ./sage. The response was as follows: type 'exceptions.ImportError': /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.1' not found (required by /root/sage-2.8.2-debian64-x86_64-Linux/local/lib/libgivaro.so.0) The error above is unfortunately fatal -- it means that the libstdc++ that the SAGE binary was linked against is much newer than the one on a Redhat EL 4 system (which is fairly old -- but stable, actually). Your options include: (1) Download the file libstdc++.so.6 that I just posted at http://www.sagemath.org/SAGEbin/linux/64bit/ and put it in SAGE_ROOT/local/lib/ and try again. This might just easily fix the problem for you. (2) Wait until I somehow get a copy of RHEL, install it, and create a binary for it. (3) Build SAGE from source yourself (this is usually very easy); you just download sage-2.8.2.tar from http://www.sagemath.org/dist/src extract the tarball, type make, and wait about 2 hours. -- William Stein Associate Professor of Mathematics University of Washington http://www.williamstein.org --~--~-~--~~~---~--~~ 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/ -~--~~~~--~~--~--~---
