By coincidence, I recently installed sage from source on a fresh ubuntu install and the instructions on http://www.sagemath.org/doc/html/inst/node5.html worked for me. In other words, if you type sudo apt-get install gcc-4.2-base # or the latest version available sudo apt-get install make

Hi, 1) Does anyone know if sage has functions that compute the fixed field for a given subgroup of the Galois group? 2) Is there a function to obtain the Artin map of an Abelian extension, or at least for the Hilbert class field of a quadratic field? Thanks, Utpal --~--~-~--~~
