GENERIC VERSION INSTALLATION INFORMATION
========================================
1. Introduction
===============
1.1. Where to look for help
---------------------------
SACLIB Maintenance
RISC-LINZ
Research Institute for Symbolic Computation
Johannes Kepler University
A-4040 Linz, Austria
E-Mail: saclib@risc.uni-linz.ac.at (Internet)
1.2. System configuration
-------------------------
This version should run on any UN*X machine requiring only minimal changes
(but note that the scripts provided are written for 'csh').
2. Installing
=============
If you are reading this file you will already have recreated the SACLIB
directory tree from your distribution '.tar' file. This will be the location
of the installed version of SACLIB. All you have to do is to simply execute
the script "saclib/sysdep/generic/install". (If you are not using 'csh' you
should first check if your shell can digest it - this should not be much of a
problem as it is rather simple.)
This installation script needs one parameter, namely the full path to the
"saclib" directory. So if your SACLIB root directory is "/usr/local/saclib"
you would type:
% /usr/local/saclib/sysdep/generic/install /usr/local/saclib
Note that it might be a good idea to use the complete path for calling the
install script as there might be some system command 'install' which might
get executed instead of the SACLIB install script.
First all system dependent files and scripts from the "generic"
directory are copied to where they belong. Then the files
- "saclib/include/sacproto.h" (which contains the prototypes for all
functions in SACLIB),
- "saclib/lib/saclib.a" (the default version of the library), and
- "saclib/doc/desc.doc" (which is used by the 'sdesc' script) are created.
To finish the installation you need to add a line to your ".cshrc" and
".login" files which sets the shell variable '$saclib' to the path of the
"saclib" directory. Following the example above, this line would look as
follows:
setenv saclib /usr/local/saclib
Finally, if you want to use the scripts in "saclib/bin", you should also add
this directory to your 'path' variable, e.g. by adding a line similar to the
following to your ".cshrc" file:
set path=($path $saclib/bin)
Note that from now on *all* accesses to SACLIB should only be done via the
'$saclib' environment variable. For example we used it for adding the SACLIB
'bin' directory to the path.
For making sure that all this was done correctly, you should log out,
log in again, and check if the 'saclib' environment variable is set. Then the
installation is complete.
3. Compiling
============
If you just need to recompile, use the command 'mklib' from "saclib/bin". This
shell script takes one of the following parameters:
'std' causes a standard library to be built. The library file will have
the name "saclib.a" and the corresponding object files are in
"saclib/lib/obj". (Note that this library was already built by the
install script.)
'deb' switches on the '-g' option of the compiler which includes
debugging information in the object files. The library file will have
the name "saclibd.a" and the corresponding object files are in
"saclib/lib/objd".
'opt' switches on the '-O' option which produces optimized code. The
library file will have the name "saclibo.a" and the corresponding object
files are in "saclib/lib/objo".
'all' builds all three types of libraries.
If you want to recompile after having added files to "saclib/src", you need to
recreate the file 'include/sacproto.h' and the makefiles first, which is done
by issuing the commands 'mkproto' and 'mkmake'.
4. Tools
========
The following shell scripts can be found in the directory "saclib/bin":
sdesc ... displays the description of a SACLIB algorithm (uses
"saclib/doc/desc.doc").
sman ... displays a SACLIB algorithm.
mkproto ... creates the file 'include/sacproto.h'.
mkmake ... creates the makefiles for SACLIB.
mklib ... compiles the library (uses the makefiles created by 'mkmake').
mkdesc ... creates the file "doc/desc.doc" from the files in "saclib/src".
The headers of these scripts contain more information on their usage.
