CWP/SU: Seismic Un*x Current Release 40 Full Source Code, Documentation, and Release Notes

Reason for the re-release. A number of users noticed that xwigb, and the derivative program xpicker, experienced windows crashing on systems where the X-libs were updated to Xorg 7.0 security update in the X-windows routine, XCreateImage. XCreateImage returns a NULL pointer causing the subroutine XPutImage to return a SIGSEGV segmentation fault error.

A kludge has been found that seems to prevent the crashing, though the program sxplot still crashes if the window is made too large.

If you have already installed Release 40 and notice the crashing window problem, then the following fix xfix.tgz may be applied (user comments and feedback is appreciated).

To install xfix.tgz:
cd $CWPROOT
zcat xfig.tgz | tar -xvf -
cd $CWPROOT/src
make xtremake

The SLT package is the work of a number of geophysicists, including Zhiming Li, Rick Ottelini and others, and most recently, Reg Beardsley. Through the generosity of Chevron, these codes have been donated to the Colorado School of Mines and the Center for Wave Phenomena for general distribution in the hopes that these will prove useful to students and research scientists everywhere.

Our ultimte goal is to absorb the great part of SLT/SU into the regular SU package. The package will install as is on a number of platforms. Because these codes were based on an earlier version of CWP/SU, there is some overlap with the CWP/SU. Also, there is mixed-language (F77 and C) programming, which may reduce portability.

The SLT codes are distributed under the same licence LEGAL_STATEMENT as the regular SU package.
