4 <title>Introduction</title>
8 <para>&clsql; is a Common Lisp interface to <glossterm
9 linkend="gloss-sql">SQL</glossterm> databases. A number of Common
10 Lisp implementations and SQL databases are supported.The general
11 structure of &clsql; is based on the
12 <application>CommonSQL</application> package by Xanalys.</para>
16 <title>History</title>
18 &clsql; is written by Kevin M. Rosenberg and based substantially
19 on Pierre R. Mai's excellent &maisql; package. The main changes from &maisql;

45 <title>Prerequisites</title>
48 <title>&defsystem;</title>
49 <para> &clsql; uses &defsystem to compile and load its
50 components. &defsystem; is included in the <ulink
51 url="http://clocc.sourceforge.net"><citetitle>&clocc;</citetitle></ulink> collection. The
52 version in the pre-packaged distribution is rather old and
53 may not function well. The version in CVS tree tree works quite
54 well. For convenience, a copy of the latest &defsystem; at the FTP
56 url="ftp://ftp.med-info.com/pub/defsystem/"><citetitle>site</citetitle></ulink>
63 <para>&clsql; uses <ulink
64 url="http://uffi.med-info.com/"><citetitle>&uffi;</citetitle></ulink>
65 as a <emphasis>Foreign Function Interface</emphasis> (<glossterm
66 linkend="gloss-ffi">FFI</glossterm>) to support multiple &cl;
67 implementations.</para>
69 <para>You can download &uffi; from its FTP <ulink
70 url="ftp://ftp.med-info.com/pub/uffi/"><citetitle>site</citetitle></ulink>. There
71 are zip files for Microsoft Windows systems and gzipped tar files for
76 <title>XPTest (optional)</title>
77 <para>The test suite for &clsql; uses the onShore Development's
78 XPTest package. onShore has graciously put the package in the public
79 domain. You can download the package from onShore's web <ulink
80 url="http://alpha.onshored.com/lisp-software/"><citetitle>site</citetitle></ulink>.
81 This package is not required except if you wish to run the &clsql;
86 <title>Supported Common Lisp Implementation</title>
88 The implementations that support &clsql; is governed by the supported
89 implementations of &uffi;. At the time of the initial release of &clsql;,
90 the following implementations are supported:
92 <itemizedlist mark="opencircle">
93 <listitem><para>&acl; v6.1 on Redhat Linux 7.2 and Microsoft Windows.</para></listitem>
94 <listitem><para>&lw; v4.2 on Redhat Linux 7.2 and Microsoft Windows.</para></listitem>
95 <listitem><para>&cmucl; 18d on Redhat Linux 7.2.</para></listitem>
100 <title>Supported &sql; Implementation</title>
102 Currently, &clsql; supports the following databases:
104 <itemizedlist mark="opencircle">
105 <listitem><para>&mysql; v3.23.49 on Redhat Linux 7.2 and Microsoft Windows.</para></listitem>
106 <listitem><para>&postgresql; v7.1 on Redhat Linux 7.2. Support for both direct API connections and TCP socket connections.</para></listitem>
107 <listitem><para>Allegro's ODBC interface (&aodbc;) on Redhat Linux 7.2 and Microsoft Windows.</para></listitem>
114 <title>Installation</title>
117 <title>Ensure &defsystem; is loaded</title>
119 Simply load the file <filename>defsystem.lisp</filename>.
121 (load "defsystem.lisp")
127 <title>Build &c; helper libraries</title>
128 <para>&clsql; uses functions that require 64-bit integer
129 parameters and return values. The &ffi; in most &clsql;
130 implementations do not support 64-bit integers. Thus, C helper
131 libraries are required to break these 64-bit integers into two compatible
132 32-bit integers.</para>
134 <para>Makefiles for Microsoft Windows and GNU/Solaris systems
135 are supplied to build the libraries. Since many Microsoft Windows
136 users don't have access to a compiler, the <type>DLL</type> and <type>LIB</type>
137 files for Microsoft Windows are supplied with the distribution.</para>
139 <para>To build the libraries on a GNU or Solaris, use the shell and
140 change to the root directory of &clsql;. You may need to edit the file
141 <filename>interfaces/mysql/Makefile</filename> to specify the location of your
142 MySQL installation. The default Makefiles are setup for shared library
143 linking on Linux. If you are using FreeBSD or Solaris, you will need
144 to change the linker setting as instructed in the Makefile.
145 Then, you can give the command
149 in the root directory of &clsql; to build the libraries
150 <filename>interfaces/mysql/clsql-mysql.so</filename> and
151 <filename>interfaces/clsql-uffi/clsql-uffi.so</filename>.
156 <title>Load &uffi;</title>
158 Unzip or untar the &uffi; distribution which creates a directory
159 for the &uffi; files. Add that directory to Defsystem's <varname>mk:*central-registry*</varname>.
160 You can do that by either pushing the pathname of the directory onto this variable, or
161 use the new <function>add-registry-location</function> present in the newest versions of
162 &defsystem;. The following example code assumes the &uffi; files reside in the
163 <filename>/usr/local/src/lisp/uffi</filename> directory.
165 (mk:add-registry-location #P"/usr/local/src/lisp/uffi")
166 (mk:load-system :uffi)
172 <title>Load &clsql; modules</title>
174 Unzip or untar the &clsql; distribution which creates a directory
175 for the &clsql; files. Add that directory to Defsystem's <varname>mk:*central-registry*</varname>.
176 You can do that by either pushing the pathname of the directory onto this variable, or
177 use the new <function>add-registry-location</function> present in the newest versions of
178 &defsystem;. The following example code assumes the &clsql; files reside in the
179 <filename>/usr/local/src/lisp/clsql</filename> directory. You need to load, at a minimum,
180 the main <symbol>:clsql</symbol> system and at least one interface system.
