Salut Nathann ! Thanks for your answer. I "touched" the files as you asked, and here is the result below. The "sage -b" command went much faster than when I first installed CPLEX.
By the way, I'm using MILP to solve machine learning problems with some combinatorial aspects. For example, given a dataset, I'm trying to find a linear separator with small integer weights. I'm comparing my own algorithms and heuristics with the result of GLPK (for now, but also CPLEX I hope).. This is for research purposes of course. regards, yann ./sage -b Building Sage on OS X in 64-bit mode Creating SAGE_LOCAL/lib/sage-64.txt since it does not exist Detected SAGE64 flag Building Sage on OS X in 64-bit mode ---------------------------------------------------------- sage: Building and installing modified Sage library files.
