Incremental Seismic Un*x Release 44R21
by John Stockwell 29 Mar '22

29 Mar '22

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.

Doubly defined global variable
by Ricardo Biloti 29 Mar '22

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, R.Biloti Applied Math.

Re: [Seisunix] Tape use
by Marc Schaming (ITES) 28 Mar '22

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.
