There isn't such a way. > Why is a > default of gfortran not used, like it is with gcc and g++ ? Because we wanted Sage to actually build on lots of computers and many systemwide compilers would fail in weird ways. > Does anyone > know why the location of the library needs to be given?

Often there are other fortran libraries installed on the system, and if one doesn't explicitly specified it, then the wrong one can get linked in. -- William > > > > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
