OCamlMySQL -- MySQL access for OCaml
*************************************

===============================
Based on a release by:
Christian Lindig
lindig@eecs.harvard.edu
http://www.eecs.harvard.edu/~lindig
==================================
ocaml-mysql is a package for ocaml that provides access to mysql
databases. It consists of low level functions implemented in C and a
module Mysql intended for application development.
1 Building
*=*=*=*=*=*
Compiling this package from sources requires the following software to
be installed on your system:
1. ocaml 3.09 or above.
2. findlib
3. The mysql client library and header files.
4. An ANSI C compiler like gcc.
A configure script is provided which should help to find the
particular files. In case configure fails, edit the setting in the
config file directly. This also applies when the C compiler fails to
find some include file. However, you should first try the obvious:
<<
% ./configure
% make
% make opt
% make install
>>
This creates the mysql libraries.
2 Trouble Shooting
*=*=*=*=*=*=*=*=*=*
If compilation fails this is most probably because include or library
files were not found. The configure looks in a number of places but may
fail to find the files on your system. In case you have GNU Autoconf
installed you can take a look at the configure.in and add more
directories to search:
<<
AC_CHECKING(for MySQL header files)
dnl
dirs="/usr/local/include
/usr/local/mysql/include
/usr/include
/usr/include/mysql"
>>
Do not forget to create a new configure script by invoking autoconf.
Please send a patch back to the author.
3. Documentation
*=*=*=*=*=*=*=*=
Check the interface files, or doc/index.html.
Reading the mysql documentation should help, too.
A small demo demo.ml is provided. You can try it in the mysqltop ocaml
interpreter that make all should have built.
Note: The library can now be used in multithreaded ocaml programs without
blocking threads during i/o with the database server. However, only one
thread should use mysql functions. Better support for multi-threaded servers
using libmysqlclient_r coming someday.
4 Copying

Lesser GNU Public License. See the file COPYING for details.
