You mean like https://github.com/sagemath/sage/pull/16 ? See http://trac.sagemath.org/ticket/15616 as well. This is a good suggestion. On Tuesday, December 31, 2013 7:57:17 PM UTC-5, Joseph P. Skudlarek wrote: > > This is a request to update the README.txt file used when building from > source

Yes, that's perfect -- thanks! And thanks for gently showing how easily it could be done -- much appreciated. /J On Wednesday, January 1, 2014 10:44:54 AM UTC-8, kcrisman wrote: > > You mean like https://github.com/sagemath/sage/pull/16 ? See > http://trac.sagemath.org/ticket/15616 as well.

It should not be enabled in the top-level make, in my opinion. Typically, "make -jN" makes parallel compiles within the same package (if the package supports it). The parallel build in sage compiles different packages in parallel, but each package still compiles as -j1. On 01/03/2014 02:48 AM
