Chris,
Interesting point. I got macos x just for the reason that you mention: a unix
platform for a powerbook g4. After getting the software, I found that many of
the tools I wanted did not compile on os x. I have not tried them all, but
enough things were missing that it is a problem. I read a number of home pages
for software to get hints, but there seem to be rather serious differences
between MacOSX and most Linux distributions. The first release of os x is
relatively new, so these problems may disappear soon.
I had hoped for a fortran compiler. Yes, I use fortran and it is alive in
some science fields. Even f2c would have been helpful. All I could find was an
os 9 application. I saw some messages that GNU gcc does not compile with the
macos x version of gcc. I had hoped to get g77 running but did not try it when
I saw that gcc would not compile. Being new, this may be my lack of experience
with linux, but I have worked with sun's version of unix so I am not entirely
without experience.
Other tools are octave (a matlab workalike), Generic Mapping Tools, NCAR
graphics and some ocean circulation models which use netCDF. Many of these have
fortran callable routines so installation requires some fortran. I tried to run
the configure script on GMT but it died at the beginning because host type was
not found.
I thought about installing YDL on an external disk just to have access to
these tools until os x became more widely used. I did not want to run a third os
on the single internal disk but I did not know how to do this on an external
disk. Firewire and usb are apparently not recognized, and there is no scsi port
on the G4 powerbook. Does anyone know how to put YDL on an external disk on the
new powerbooks?
Thanks in advance. Sorry if this is not the place for a YDL vs MacOS X
discussion.
