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(a)gmail.com <mailto:john.19071969@gmail.com> so we can discuss how best to include the code.
Thank you for using Seismic Un*x.

——— Release notes for 44R21 ----
Summer 2018 - Thanks to Dominque Rousset of the University of Pau,

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

Hi folks
I've been trying to compile SU R22..24 on a Debian 11 with gcc 10.2.1
(20210110), but there is an error.
make[4]: Entering directory '/usr/local/stow/su/src/su/main/filters'
/usr/bin/gcc -I/usr/local/stow/su//include -g -m64 -Wno-long-long
-DCWP_LITTLE_ENDIAN sulfaf.c -L/usr/local/stow/su//lib -lsu -lpar -lcwp
-lm -o /usr/local/stow/su//bin/sulfaf
*/usr/bin/ld:
/usr/local/stow/su//lib/libsu.a(fputgthr.o):/usr/local/stow/su/src/su/lib/fputgthr.c:51:
multiple definition of `tr';
/usr/local/stow/su//lib/libsu.a(fgetgthr.o):/usr/local/stow/su/src/su/lib/fgetgthr.c:66:
first defined here*
collect2: error: ld returned 1 exit status
make[4]: [Makefile:35: /usr/local/stow/su//bin/sulfaf] Error 1 (ignored)
chmod: cannot access '/usr/local/stow/su//bin/sulfaf': No such file or
directory
The source for this bug is that the global variable tr is defined in
src/su/lib/fgetgthr.c as well as in src/su/lib/fputgthr.c. Both objects are
combined to build libsu.a.
After a little googling, I found out that gcc 10.2 set -fnocommon as
default now. So, adding -fcommon in Makefile.config fix the issue, but
perhaps a better fix would be to place an extern across the multiple
definitions of tr.
Kind regards,

Hi,
depends on how many tape devices you have !
Generally seismic tapes are record oriented, is bloack may have differents length.
If you have 2 tape devices, tcopy is useful.
If not, you'll have to make a disk-copy, and then restore disk-copy to tape in the original set.
You'll have to know the structure of the tape (ie length of each block).
Using these informations you may use dd, or another program to copy to/from disk that take length into account.
There are 2 seismic formats that could deal with this:
SEG-RODE
TIF, tape interchange Format.
Cheers,
Marc
