Hello, Yesterday, I tried to build the development branch of Sage on my machine and failed. Apparently, the error occurs when attempting to build conway_polynomials-0.4.p0.
Here are my machine specs: Lubuntu 14.10 Virtual Machine running on Mac OSX Lion The underlying hardware is a MacbookAir. In particular, it is a 64 bit processor. I'm posting the error message below. Please let me know if you need any further information, and of course, if anyone can help me to get the build to work. Thanks! Dinakar Muthiah Here is the error message that I get from the build (in particular, it suggests I post the message here).
