Huh. Why aren't you using gfortran?
Oh yes - *uhhfff*, things would be much easier. It all started in the
beginning of 2007 when Paul Kienzle and me started to create Octave.app for
MacOSX... Ok, ok, I tell you the short story ;)
Apple doesn't provide *all* of the GNU Compiler Collection, eg. gfortran,
gcj and others are missing but at least the C/C++ 4.0.1 compilers are there.
Creating a full compiler collection for myself would generally be possible,
creating a *working* cross compiler collection for me and others for a PPC
and i386 platform (like the one that already is installed on my Mac) is
incredibly incredibly incredibly hard (this is where the other story begins
about how to build universal binaries and a linker that combines all these
codes in one dynamic lib and ...). Apple uses f2c (at least on MacOSX 10.3.x
and 10.4.x machines - don't have any knowledge about 10.5.x) to build the
high performance '-framework vecLib' and other Fortran libs in the SDK (at
least that's what they say on their developer's website). The '-framework
vecLib' is used by Octave sources instead of a self made blas/lapack, so the
most compatible way to create binaries is that I use f2c, too.
OK, I understand, the reasoning is good. One thing that surprises me
is that a company like Apple uses an unmaintained product like f2c
instead of investing, e.g., into porting gfortran to their platform. I
guess they only use f2c to build the Fortran interface, because any
computational code compiled by f2c + whatever C compiler would be
easily outperformed by using a fortran compiler directly.
Huh. Apparently another company that considers Fortran dead. Sigh.
Fortran is a zombie - a Terry Pratchett's zombie. It died, but it
continues to unlive, within a small, active community, enjoying its
afterlife. You may ignore it, but it's still around, while the
mainstream languages are consistently failing to replace it.
Btw, the f2c compatibility is usually no problem - most compilers
(gfortran included) provide a flag to ensure it. But of course I
understand that you don't want to build gfortran yourself - I was
always under the impression that the entire gcc is ported to Mac.
Btw2, for those still interested in Fortran, has anyone checked g95
recently? Wow, eh?
