I'm trying to cross-compile R on a Mac OS X box to target Win32. It
works quite well, everything works, except for one fortran file ppr.f
in the stats package:
---------- Making package stats ------------

It's just a "block data" with some common variables that are
initialized en-block. Obviously g77 tries to copy the whole block and
bails out, because it's unsure about the endianness conversion (could
be int/double whatever). My Fortran knowledge is rather limited, so can
anyone provide me with alternate Fortran code that will use regular
assignments instead of the "block data", so we can work around the
missing feature of the compiler? If someone has a different idea,
that's fine, too :).
Otherwise it works very nicely, the compiled R works (except that stats
is not compiled of course) ... Solving the above would allow us to
provide binary packages for both platforms OS X and Windows using just
one machine to automatically generate both... (for those interested I
could put the cross-compile tools on my pages..)
Any help is appreciated,
Simon
