Dear Seismic Unix user,

I have put some fixes in for the Fortran codes and for the SFIO installations so that you should be able to install everything. Mac OS X  Big Sur was a painful upgrade.  As you might guess, I am preparing for Release 45. 

If you have codes that can be shared under the Berkeley style license (no GPL), that is in the style of SU, but honors the existing header structure, has a demo that generates its own data, and that you would like to have included in SU, please email me at: john.19071969@gmail.com <mailto:john.19071969@gmail.com> so we can discuss how best to include the code.

Thank you for using Seismic Un*x.

Installation tip. If you get error messages regarding the XDR materials
you may need to install libtirpc from your Linux distribution.

if you have questions, or if you want to supply  bug fixes or new SU code.

What is new in the SU package:

                character*120 fnames(2) from fnames(3)
                Thanks to Fernando Roxo da Motta
Fortran/Raytrace3d/ktime_3d_rayq.f - ERROR of argument mismatch in two
                locations.
                fix: added -fallow-argument-mismatch to the
                FFLAGS in Makefile.config_Big_Sur  this might need to
                be propagated to all of the Makefile.config_* and this
                likely takes care of the vzestf.f error as well.

        Replaced these files with versions from the 2002 release of sfio.
        ./src/lib/sfio/Stdio_b/sprintf.c
        ./src/lib/sfio/Stdio_b/vsprintf.c
        ./src/lib/sfio/Stdio_s/stdsprintf.c
        The make sfio should work now.

demos/Ordinary_differential_equations  - has been added to go with the new
        ordinary_differential equation items in par/main
