Strauss: Software Changes

Strauss: Software Changes - Feb 2005

Overview

IT staff have upgraded and deleted some software versions, and modified some symbolic links and executable files recently. If you have any questions about these changes, please send a note to rdms-info@udel.edu.

The changes affect the following:

Standard UNIX default path
GNU compilers
Java
Maple
Mathematica
Matlab
Sun's Studio 9 compilers
TeX and LaTeX

UNIX environment changes

The "current working directory" is no longer in the default path. This change to /usr/proto/localenv was done for security reasons.
You may see the message "command not found" after typing a.out.
One solution is to type ./a.out instead.
/opt/gnu/bin and /opt/gnu/man are no longer in the standard default PATH and MANPATH.

Contents

GNU software

We suggest that you use the GNU compilers in /opt/sfw. That directory also contains debuggers and third-party libraries including gdb and ddd.

/opt/gcc links to the directory containing the newest gcc compiler that IT supports. Newer compilers may be installed, but should be viewed as being in test mode.

/opt/gnu, the symbolic link to /opt/gnu2.8.1, was deleted.

The /opt/gnu2.8.1 software will be deleted this summer.

Older /opt/gcc-2x and /opt/gcc-3x versions have been deleted.

Contents

Java

Most of the changes reflect an attempt to standardize the names of the directories and symbolic links.

The most current release is version 1.4.x

See /usr/java*, /opt/java*, and /usr/jdk* for changes.

Changes to symbolic links:
- /usr/j2se and /usr/j2sdk now point to /usr/java1.4
- /usr/java points to /opt/java1.4
- /usr/java1.x points to Java 1.x

Contents

Maple

Maple 9.5 is the current default version.

/opt/bin/maple and /opt/bin/xmaple now execute Maple 9.5.

Maple 8 is still available via /opt/bin/maple8 and /opt/bin/xmaple8.

Maple 9 is still available via /opt/bin/maple9 and /opt/bin/xmaple9.

Contents

Mathematica

Mathematica 5.0.1 is the current default version.

/opt/bin/math and /opt/bin/mathematica now execute Mathematica 5.0.1

Mathematica 5.1 is accessible now via /opt/bin/math5.1 and /opt/bin/mathematica5.1.

Mathematica 5.1 will soon become the default.

Contents

Matlab

Matlab 7 (SP1) is the current default version.

/opt/bin/matlab now executes Matlab 7 (SP1)

/opt/bin/matlab_6.5_r13_1 runs Matlab 6.5 R13.1

All other Matlab versions have been deleted.

Contents

Sun Studio 9

We suggest that you use the new Sun compilers in the Studio 9 suite. They are more robust and work better than previous Sun compilers, especially if you also use the IMSL Computational Toolkit (CTT).

Documentation is in http://www.udel.edu/topics/software/special/statmath/ctt/

Sun Studio 9's Sun Performance Library installation will be completed shortly.

Contents

TeX and LaTeX

/opt/texlive-2004 was installed as the new default version of Tex and LateX.

/opt/tex/bin now points to the texlive-2004 binaries.

Documentation is in http://www.udel.edu/topics/software/general/wordproc/unix/tex.latex/.
