<h2>REQUIRMENTS:</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Don't get intimidated, this is just to cover all bases, most computer
|
||
|
|
systems meet the requirements.<p>
|
||
|
|
|
||
|
|
<b>PERL</b>: Yes, preferably Perl 5.004.04 or greater.
|
||
|
|
|
||
|
|
<p> <b>FTP CAPABILITIES (optional)</b>: You may need to get <A
|
||
|
|
HREF="ftp://www.perl.com/pub/perl/CPAN/modules/by-category/05_Networking_Devices_IPC/Net/libnet-1.0606.tar.gz">Net::FTP</A>
|
||
|
|
(Debian libnet-perl package) which depends on Data::Dumper (Debian
|
||
|
|
data-dumper package). You also need <b>gcc</b> if you do not have a
|
||
|
|
Debian system so that <em>swim</em> can figure out what architecture your
|
||
|
|
machine is. You can also find these modules at the <A
|
||
|
|
HREF="http://www.perl.com">CPAN mirrors</A> or the PACKAGES below.
|
||
|
|
|
||
|
|
<p> <b>READLINE CAPABILITIES (optional)</b>: For nice readline
|
||
|
|
cpabilities get <A
|
||
|
|
HREF="ftp://www.perl.com/pub/perl/CPAN/modules/by-module/Term/Term-ReadLine-Gnu-1.03.tar.gz">Term::ReadLine::Gnu</A>
|
||
|
|
or alternatively <A
|
||
|
|
HREF="ftp://www.perl.com/pub/perl/CPAN/modules/by-module/Term/Term-ReadLine-Perl-0.990
|
||
|
|
6.tar.gz">Term::ReadLine::Perl</A> which depends on <A
|
||
|
|
HREF="ftp://www.perl.com/pub/perl/CPAN/modules/by-module/Term/TermReadKey-2.12.tar.gz">Term::ReadKey</A>
|
||
|
|
. <em>Term::ReadLine::Gnu</em> may be tricky to set-up on non Debian
|
||
|
|
systems because it depends on <em>ncurses3.4</em> and the <em>GNU Readline
|
||
|
|
Library version 2.1 or later</em>, but <em>Term::ReadLine::Perl</em> is
|
||
|
|
much easier to set-up and allows a huge amount of package names to be
|
||
|
|
present on the command line without a segmentation fault. You could get
|
||
|
|
swim's ftp capabilities working first, and then just fetch the Debian
|
||
|
|
ReadLine package(s) and then use swim's --extract option to set the
|
||
|
|
package(s) up, but, it is sure fun doing a 'make test' when setting up the
|
||
|
|
ReadLine modules! You can also find these modules at the <A
|
||
|
|
HREF="http://www.perl.com">CPAN mirrors</A> or the PACKAGES below. <p>

<b>DATABASE CAPABILITIES</b>: DB_File comes standard with Perl. But,
|
||
|
|
this doesn't mean it is compiled for the newer Berkeley Database
|
||
|
|
Libraries. DB 1.85 has
|
||
|
|
known <A
|
||
|
|
HREF="http://www.sleepycat.com/historic.html">
|
||
|
|
bugs</A> which effect SWIM. SWIM can work with
|
||
|
|
1.85, but <kbd>--rebuildflatdb</kbd> and <kbd>--rebuildflatndb</kbd> will
|
||
|
|
not work properly. You can run a test to find out whether or not you need
|
||
|
|
to make the change if you have db_dump available on your system (which
|
||
|
|
db_dump). Enter this:
|
||
|
|
|
||
|
|
<P>
|
||
|
|
<code>perl -e 'use DB_File; tie %testdb,'DB_File',"testdb";';<br>
|
||
|
|
db_dump testdb</code>
|
||
|
|
|
||
|
|
<P>If 'db_dump testdb' produces an error you need to make the change by
|
||
|
|
installing the newest DB_File. If you have a version of libc6 less than
|
||
|
|
2.1, first, install a new version ( 2.3.4 or greater) of the <A
|
||
|
|
HREF="http://www.sleepycat.com">Berkeley DB</A> if you don't already
|
||
|
|
have it installed. If you get
|
||
|
|
<A
|
||
|
|
HREF="ftp://www.perl.com/pub/perl/CPAN/modules/by-module/DB_File/DB_File-1.65.tar.gz">
|
||
|
|
DB_File</A>
|
||
|
|
from CPAN you will need to edit
|
||
|
|
config.in to point to the location of where libdb2 installed db.h, where
|
||
|
|
libdb2 is installed on your system, and the name of the library. For
|
||
|
|
Debian this would be:
|
||
|
|
|
||
|
|
<P><code>INCLUDE = /usr/include/db2<br>
|
||
|
|
LIB = /usr/lib<br>
|
||
|
|
DBNAME = -ldb2</code>
|
||
|
|
|
||
|
|
<p><b>PACKAGES</b>: You can get the CPAN modules in some package formats.
|
||
|
|
Debian 2.1 and Red Hat 5.0 have been tested with these packages:

<b>USER</b>: root. Some of swim's most important functions will not work
|
||
|
|
properly unless you are running the program as root.
|
||
|
|
|
||
|
|
<p><b>HARD DRIVE SPACE</b>: Make sure you have enough hard drive space.
|
||
|
|
1500
|
||
|
|
installed packages produces a 10MB fileindex.deb, and the virtual
|
||
|
|
not-installed filesystem database for the unstable distribution is now
|
||
|
|
over 40MB. 100MB of free space on your hard drive is probably a good
|
||
|
|
safety margin, if you run out of hard drive space the program will just
|
||
|
|
hang or quit.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<b>MEMORY</b>: Databases made for an installed Debian system require
|
||
|
|
memory in proportion to the amount of packages actually installed; the
|
||
|
|
<kbd>--lowmem</kbd> option is an excellent alternative for making the
|
||
|
|
databases if the computer system is either overloaded or low on memory.
|
||
|
|
If you get "out of memory" warnings try to free up some memory first then
|
||
|
|
make the databases. You can also avoid making the virtual filesystem by
|
||
|
|
not using the <kbd>--Contents</kbd> option or using the FDB argument for
|
||
|
|
that option. Updating the databases uses very little memory.
|
||
|
|
|
||
|
|
<p> <b>OTHER SWIM FUNCTIONS</b>: Most free operating systems have these
|
||
|
|
packages installed: On a non Debian system, <b>ar</b> from
|
||
|
|
<em>binutils</em> is used to query Debian binary packages. These next
|
||
|
|
packages are essential in a free operating system (Linux) -
|
||
|
|
<em>textutils</em>, <em>fileutils</em>, <em>grep</em>, <em>tar</em>,
|
||
|
|
<em>gzip</em>, and <em>mount</em>.
