To use Sage 4.7.1 on Ubuntu 11.10 you will have to build it from source using the gcc-4.4 compiler (instead of the default gcc-4.6). To do this follow these steps:
- open a terminal (ctrl-alt-t) - install gcc-4.4 compiler by running these commands in the terminal: sudo apt-get install gcc-4.6 gcc-4.4-base gcc-4.4 cpp-4.4 g++-4.4 gfortran-4.4 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 100 --slave /usr/bin/cpp cpp /usr/bin/cpp-4.6 --slave /usr/bin/g++ g+ + /usr/bin/g++-4.6-slave /usr/bin/gfortran gfortran /usr/bin/ gfortran-4.6 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 80 --slave /usr/bin/cpp cpp /usr/bin/cpp-4.4 --slave /usr/bin/g++ g++ / usr/bin/g++-4.4 --slave /usr/bin/gfortran gfortran /usr/bin/ gfortran-4.4 - switch to the gcc-4.4 alternative by selecting it from the list after running: sudo update-alternatives --config gcc - download the source package from: http://www.sagemath.org/download-source.html - in the terminal change directory to the downloaded package: cd ~/Downloads/ - unpack the package: tar xf sage-4.7.1.tar - change dir to unpacked sage: cd sage-4.7.1/ - build the source by running (will take many hours): make - afterwards switch back to the gcc-4.6 alternative by selecting it from the list after running: sudo update-alternatives --config gcc - now you can run sage with: ./sage - start the notebook with: notebook() Regards, Bas -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
