I would suggest you put the 4.3 gcc and g++ somewhere in $PATH before gcc and g++ - Sage will then use them automatically. > export SAGE_FORTRAN=/usr/bin/gfortran-4.3 Same as the above for the name. But it will likely work > export SAGE_FORTRAN_LIB=/usr/lib/libgfortran.so.3 ATLAS only links to libgfortran.so for some reason, so either link it against that name or copy it somewhere as libgfortran.so and point SAGE_FORTRAN_LIB to it. Another alternative is to start the build and then copy libgfortran.so.3 into SAGE_LOCAL/lib as libgfortran.so before ATLAS get going. > However, I get a "ld: cannot find -lgfortran" while building atlas-3.8.1.p1. > > What is the correct syntax for "SAGE_FORTRAN_LIB"? > > Actually: the install.log doesn't show any trace of using > "gfortran-4.3" as a binary.

But I think gfortran should work fine as long as it > is called by "gfortran-4.3". Well, many people seem to disagree with you ;) - some times you should be able to set some env variable to point it to gfortran-4.3. I think in the vast majority of cases configure checks for some Fortran compiler ever though they do not compile any Fortran code. Sigh ... autohell ;) > Gonzalo Cheers, Michael --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
