-This is a simple 'HOWTO' document describing how to
-build MySQL binaries for versions 4.1 and above on
-Windows. Instructions are provided for building binaries
-from a standard source distribution or from the BitKeeper
-tree that contains the latest development source.
---------------------------------------------------------
-NOTE
---------------------------------------------------------
-Normally, it is best to use precompiled binary distributions
-of MySQL that are built specifically for optimal performance
-on Windows by MySQL AB.  Binary distributions are available
-from:
-http://www.mysql.com/downloads/
-The instructions in this document are strictly for users
-who want to test MySQL on Windows from the latest source or
-from the BitKeeper tree, and for internal MySQL developers.
--------------------------------------------------------

--------------------------------------------------------
-1. REQUIREMENTS
-2. OBTAINING A WINDOWS SOURCE DISTRIBUTION
-3. CREATING A SOURCE PACKAGE FROM THE 'BitKeeper' TREE
-4. BUILDING 'mysql server and clients' FROM VC++ WORKSPACE
-5. BUILDING FROM 'nmake' MAKEFILES
-6. STARTING THE MYSQL SERVER FOR THE FIRST TIME
-7. TESTING THE CONNECTION
-8. SPECIAL NOTES AND CONSIDERATIONS
-------------------------------------------------------
-1. REQUIREMENTS
-------------------------------------------------------
-To build MySQL on Windows from source, you need the
-following compiler and resources available on your Windows
-system:
-   - Microsoft Visual C++ 6.0 and above
-   - ~45 MB disk space
-   - 64 MB RAM
-You'll also need a MySQL source distribution, which you
-can obtain as described in section 2.
-------------------------------------------------------
-2. OBTAINING A WINDOWS SOURCE DISTRIBUTION
-------------------------------------------------------
-There are two ways you can get a Windows source distribution
-for MySQL version 4.1 and above:
- I.  Obtain a MySQL AB-distributed source distribution for the
-     particular version of MySQL in which you are interested.
-     Prepackaged source distributions are available for released
-     versions of MySQL and can be obtained from:
-     http://www.mysql.com/downloads/
- II. Alternatively, you can package a source distribution
-     yourself from the latest BitKeeper developer source
-     tree. If you plan to do this, you must create the
-     package on a Unix system and then transfer it to your
-     Windows system.  (The reason for this is that some of the
-     configuration and build steps require tools that work only
-     on Unix.)  The BitKeeper approach thus requires:
-     - A system running Unix, or a Unix-like system such as Linux
-     - BitKeeper 3.0 installed on that system (you can obtain
-       BitKeeper from http://www.bitkeeper.com)
-If you are using the first option, you can skip the  next
-section and go directly to "BUILDING 'mysql server & clients'
-FROM VC++ WORKSPACE"
-------------------------------------------------------
-3. CREATING A SOURCE PACKAGE FROM THE 'BitKeeper' TREE
-------------------------------------------------------
-To build the latest Windows source package from the current
-BitKeeper source tree, use the following instructions. Please
-note that this procedure must be performed on a system
-running a Unix or Unix-like operating system.  (The procedure
-is known to work well on Linux, for example.)
- Clone the BitKeeper source tree for MySQL (version 4.1
-  or above, as desired).  For more information how to clone
-  the source tree, see the instructions at:
-  http://www.mysql.com/doc/en/Installing_source_tree.html
- Configure and build the distribution so that you have a
-  server binary to work with.  One way to do this is to run
-  the following command in the top-level directory of your
-  source tree:
-  ./BUILD/compile-pentium-max
- After making sure that the build process completed successfully,
-  run the following utility script from top-level directory
-  of your source tree:
-  ./scripts/make_win_src_distribution
-  This script creates a Windows source package, to be used on
-  your Windows system.  You can supply different options to the
-  script based on your needs. It accepts the following options:
-    --debug   Debug, without creating the package
-    --tmp     Specify the temporary location
-    --suffix  Suffix name for the package
-    --dirname Directory name to copy files (intermediate)
-    --silent  Do not list verbosely files processed
-    --tar     Create tar.gz package instead of .zip
-    --help    Show this help message
-   By default, make_win_src_distribution creates a zipped
-   archive with the name mysql-$version-win-src.zip, where
-   $version represents the version of your MySQL source tree.
- - Copy or upload to your Windows machine the Windows source
-   package that you have just created. To compile it, use
-   the instructions in the next section.
---------------------------------------------------------
-4. BUILDING 'mysql server & clients' FROM VC++ WORKSPACE
---------------------------------------------------------
-NOTE: MySQL 4.1 and above VC++ workspace files are compatible
-      with Microsoft Visual Studio 6.0 and above(7.0/.NET)
-      editions and tested by MySQL folks before each 
-      release.
-Unpack the Windows source zipped archive to a folder and open 
-mysql.dsw from your top-level directory.
-If you want to build both release and debug versions, then
-select 'build' -> 'buildall' option. To build only release
-or debug versions, select all appropriate workspaces from
-the 'build' -> 'batch build' option.
-The simplest solution to building the basic clients and core
-server is to set your current active workspace as 'mysqld'
-release or debug version, and just hit 'build' or 'F7', which
-creates the necessary client binaries in the 'client_release'
-or 'client_debug' directories. The libraries are placed in the
-'lib_release' and 'lib_debug' directories for release and
-debug versions, respectively.
-Now you have built the distribution. If you get any compiler
-errors, please cross check and email the compiler output to 
-win32@lists.mysql.com for further assistance.
---------------------------------------------------------
-5. BUILDING FROM 'nmake' MAKEFILES
---------------------------------------------------------
-TODO from MySQL PIEFU team.
---------------------------------------------------------
-6. STARTING THE MYSQL SERVER FOR THE FIRST TIME
---------------------------------------------------------
-The server built using the preceding instructions will
-expect that the MySQL base directory and data directory
-are C:\mysql and C:\mysql\data by default. If you want to
-test your server using the source root directory and its
-data directory as the base directory and data directory,
-you will need to tell the server their pathnames. You can
-either do this on the command line with the --basedir
-and --data-dir options, or place appropriate options in
-an option file (C:\my.cnf or the my.ini file in your
-Windows directory). If you have an existing data directory
-elsewhere that you want to use, you can specify its pathname
-instead.
-Start your server from the 'client_release' or 'client_debug'
-directory (depending on which server you want to use). The
-general instructions are given here:
-http://www.mysql.com/doc/en/Windows_installation.html
-You'll have to adapt the instructions appropriately if you
-want to use a different base directory and/or data directory.
-That's all!!! See, it's as simple to build MySQL on Windows
-as on any other platform!!!
---------------------------------------------------------
-7. TESTING THE CONNECTION
---------------------------------------------------------
-Once the server is running in standalone fashion or as a
-service based on your configuration, try to connect to it
-from the 'mysql' command line SQL interactive utility that
-exists in your 'client_release' or 'client_debug' directory.
---------------------------------------------------------
-8. SPECIAL NOTES AND CONSIDERATIONS
---------------------------------------------------------
- For production use, MySQL AB does not advise using a MySQL
-  server built by yourself from source. It is preferable to
-  stick to using binaries shipped by MySQL AB.
- If you find something not working as expected, or you have
-  suggestions about ways to improve the current build process
-  on Windows, please email to win32@lists.mysql.com.
-Thanks
