This section presents additional information which may be helpful to the LAS software maintainer. This information pertains to the Linux version of LAS; it differs somewhat from the Sun Solaris environment.

| LAS_XMLIB | = | /usr/openwin/lib/libXm.so |
| LAS_XMINC | = | /usr/include/Xm | ||

Tools Required for Building LAS
| pdfhtml | Create an HTML-format User's Guide from a .pdf file. | |
| setup_las_csh | Set all environment variables needed for building LAS modules (C-shell users). | |
| setup_las_bash | Set all environment variables needed for building LAS modules (Bash-shell users). |
These tools use the alpha.mdl and hierarchy.menus files in directory las/local/app/menus to build menus and perform supporting functions. Their usage is described in detail as part of the instructions for installing LAS, under the heading "Modifying LAS Menus".
| bldmdf.pl |
Build .mdf menu files using the codes and hierarchy defined by
alpha.mdl and hierarchy.menus.
| bldught.pl |
Build HTML tables of contents for the User's Guides, including a
functional listing having the same structure as the menus, and a
separate alphabetical listing.
| listmdf.pl |
List all applications modules assigned to each second-level menu
category.
| listpgm.pl |
List only the names of all applications modules included in file
alpha.mdl.
| |
| printddr | Print the data descriptor records for a file without invoking LAS -- this facilitates accessing DDR fields from shell or Perl scripts. | |
| log_psumods | Create an entry in a CVS/PSUmods file to record PSU-specific modifications in a standard format. | |
| run_las | Start an LAS interactive session or run a single LAS command. | |
| summ_applog.pl | Create summary of LAS usage by each user listed in the logfile(s). |
| TIEpts.ad | The "xresources" file used by the tiepts Xwindows application. | |
| dellines | Delete "newline" characters from a file. | |
| fpr | Convert printer-control characters in a Fortran formatted output file to Unix-comaptible control characters. | |
| host2las | Convert filenames from standard Unix syntax to Catalog Manager syntax. | |
| htmlascii | Convert HTML files to plain ASCII text. | |
| las2host | Convert filenames from Catalog Manager syntax to standard Unix syntax. | |
| newlines | Insert "newline" characters after every n-th character in a file, where n is specified by the user. |
The on-line help facility for the Xwindows applications xid and tiepoints and the hypertext version of the user manual use the Netscape browser. The Netscape browser is available for free download from URL http://www.netscape.com/download.
The Xwindows applications also make use of the Xwindows support libraries supplied by the operating system. Some of the libaries supplied with versions of Sun Solaris prior to 2.6 are not compatible with more recent versions; this problem is discussed in greater detail in the section on LAS installation. See also the note about file TIEpts.ad in Section 3.5.
Some applications make use of a public domain graphics software package called gnuplot that is not included within the LAS distribution. Gnuplot is available via anonymous ftp from ftp://ftp.dartmouth.edu/pub/gnuplot.
Some of the LAS system management tools use the Perl scripting language. The scripts expect to find the perl compiler/interpreter in directory /opt/local/bin/. Perl can be downloaded from http://www.perl.com/.
For (re)building LAS applications, the GNU gcc compiler is recommended; it is specified by the enviroment variable CC defined in the script env/las/assign/pgmassign. This compiler may be downloaded from http://www.gnu.org/.
Equations that are found in the Description/Algorithm section of the user guides have not been standardized and, therefore, may be confusing.
