OCaml-MySQL -- MySQL access for OCaml ************************************* http://ocaml-mysql.forge.ocamlcore.org/ ======================================= Based on a release by: Shawn Wagner shawnw@speakeasy.org http://raevnos.pennmush.org/code/ocaml-mysql ============================================ 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 C bindings to libmysqlclient 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. 1' Building on windows *=*=*=*=*=*=*=*=*=*=*=* Compiling this package from sources requires the following software to be installed on your system: 1. ocaml 3.11 or above with accompanying C compiler setup (msvc or mingw) 2. findlib 3. MySQL Connector/C 4. GNU Make ocaml/msvc : Copy Makefile.msvc to Makefile and edit MYSQL_DIR variable to point to the root of installed MySQL Connector/C distribution. Afterwards run `make` to build mysql library, `make demos` to compile examples and `make install` to install with ocamlfind. ocaml/mingw: Some mingw reimp versions can't process libmysql.lib import library. In such cases try to rename this file into "$M/lib/libmysql.a" without any processing by reimp. $ export P="c:/Program Files/MySQL/MySQL Connector C 6.0.2" $ export M="c:/mingw" $ cp "$P/lib/opt/libmysql.lib" "$M/lib/" $ (cd "$M/lib" && reimp libmysql.lib && mv liblibmysql.a libmysql.a) $ CPPFLAGS="-I$P/include" ./configure $ make all opt demos 2 Troubleshooting *=*=*=*=*=*=*=*=*= 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/mysql/html/index.html (generated with `make htdoc`). Reading the mysql documentation should help, too. Two small demos are available. Build them with `make demos`. Note: The library can be used in multithreaded ocaml programs without blocking threads during i/o with the database server. Since MySQL 5.5 it is safe to share database handle between threads in most scenarios, see http://dev.mysql.com/doc/refman/5.5/en/c-api-threaded-clients.html 4 Copying *=*=*=*=*= You are encouraged to distribute this code under the terms of the Lesser GNU Public License.
