Hi:
I had apparently installed the Sage-provided scripts
sage-g77_shared
sage_fortran
when Sage was under /opt to get some fortran functionality from within the
notebook. Of course that functionality is missing with Sage under /usr. Both
scripts are needed. See, from the notebook,
Help -> Fast Static Versions -> Numerical Sage -> f2py
for a cut-N-paste example. This example is included (command line version) in
inline_fortran.py, the InlineFortran class under site-packages/sage/misc. The
sage-g77_shared script calls sage_fortran and sage-g77_shared is hardcoded in
the InlineFortran class. I suppose it is somewhat awkward to have these two
scripts, but thought I would point out that some functionality is missing
without them. Perhaps there is a better way, without messing around with the
InlineFortran class, to achieve the same result.

Thats absolutely right - thank you for pointing that out. I have added these
files for now, but I think I will write a fix so we wont need these.

Relative to the included files, it appears that with the Sage-provided
sage-g77_shared script, sage_fortran can't just point to the fortran compiler
since sage_fortran needs to have arguments, i.e. the "$@" is needed in using
sage_fortran.

"$@" just adds the command line arguments given to sage_fortran to fortran,
which is what a symlink implicitly does.

Perhaps so, but things don't work as they are presently. Maybe the python
script messes up things. If I replace, in the sage-g77_shared script,
sage_fortran with the path to the fortran compiler then things work. The
symlink
/usr/bin/sage_fortran -> x86_64-pc-linux-gnu-gfortran
on my machine will then not be used.

Ok I did that replacement - (should be) fixed in latest commit!
