You should read this section only if you are interested in helping us test our new code. If you just want to get MySQL up and running on your system, you should use a standard release distribution (either a binary or source distribution).
To obtain the most recent development source tree, you must have Bazaar installed. You can obtain Bazaar from the Bazaar VCS Web site. Bazaar is supported by any platform that supports Python, and is therefore compatible with any Linux, Unix, Windows or Mac OS X host. Instructions for downloading and installing Bazaar on the different platforms are available on the Bazaar Web site.
All MySQL projects are hosted on Launchpad. MySQL projects, including MySQL server, MySQL Workbench, and others are available from the Sun/MySQL Engineering page. For the repositories related only to MySQL server, see the MySQL Server page.
To build under Unix/Linux, you must have the following tools installed:
GNU make, available from http://www.gnu.org/software/make/. Although some platforms come with their own make implementations, it is highly recommended that you use GNU make. It may already be available on your system as gmake.
autoconf 2.58 (or newer), available from http://www.gnu.org/software/autoconf/.
automake 1.8.1, available from http://www.gnu.org/software/automake/.
libtool 1.5, available from http://www.gnu.org/software/libtool/.
m4, available from http://www.gnu.org/software/m4/.
bison, available from http://www.gnu.org/software/bison/. You should use the latest version of bison where possible. Version 1.75 and version 2.1 are known to work. There have been reported problems with bison 1.875. If you experience problems, upgrade to a later, rather than earlier, version. Versions of bison older than 1.75 may report this error:
sql_yacc.yy:#####: fatal error: maximum table size (32767) exceeded
The maximum table size is not actually exceeded; the error is caused by bugs in older versions of bison.
To build under Windows you must have Microsoft Visual C++ 2005 Express Edition, Visual Studio .Net 2003 (7.1), or Visual Studio 2005 (8.0) compiler system.
Once the necessary tools are installed, you must create a local branch of the MySQL source code on your machine:
To obtain a copy of the MySQL source code, you must create a new Bazaar branch. If you do not already have a Bazaar repository directory set up, you need to initialize a new directory:
bzr init-repo --trees mysql-server
Once you have an initialized directory, you can
branch from the public MySQL server
repositories to create a local source tree. To create a branch
of a specific version:
bzr branch lp:mysql-server/5.1 mysql-5.1
The initial download will take some time to complete, depending on the speed of your connection. Please be patient. Once you have downloaded the first tree, additional trees should take significantly less time to download.
When building from the Bazaar branch, you may want to create a copy of your active branch so that you can make configuration and other changes without affecting the original branch contents. You can achieve this by branching from the original branch:
bzr branch mysql-5.1 mysql-5.1-build
To obtain changes made after you have set up the branch
initially, update it using the
periodically. Use this command in the top-level directory of
the local copy:
You can examine the changeset comments for the tree by using
log option to bzr:
shell> bzr log
You can also browse changesets, comments, and source code online. To browse this information for MySQL 5.1, go to the Launchpad MySQL Server page.
If you see diffs (changes) or code that you have a question
about, do not hesitate to send email to the MySQL
internals mailing list. See
Section 1.6.1, “MySQL Mailing Lists”. Also, if you think you have a
better idea on how to do something, send an email message to
the list with a patch.
After you have the local branch, you can build MySQL server from the source code. On Windows, the build process is different from Unix/Linux: see Section 2.5.10, “Installing MySQL from Source on Windows”.
On Unix/Linux, use the autoconf system to create the configure script so that you can configure the build environment before building. The following example shows the typical commands required to build MySQL from a source tree.
Change location to the top-level directory of the source tree;
mysql-5.1 with the
appropriate directory name.
Prepare the source tree for configuration.
Prior to MySQL 5.1.12, you must separately configure the
InnoDB storage engine. Run the following
command from the main source directory:
(cd storage/innobase; autoreconf --force --install)
You can omit the previous command for MySQL 5.1.12 and later,
or if you do not require
Prepare the remainder of the source tree:
autoreconf --force --install
As an alternative to the preceding autoreconf command, you can use BUILD/autorun.sh, which acts as a shortcut for the following sequence of commands:
libtoolize --automake --forceshell>
automake --force --add-missing; autoconf
If you get some strange errors during this stage, verify that you have the correct version of libtool installed.
Configure the source tree and compile MySQL:
./configure # Add your favorite options hereshell>
For a description of some configure options, see Section 2.3.2, “Typical configure Options”.
A collection of our standard configuration scripts is located
BUILD/ subdirectory. For example,
you may find it more convenient to use the
BUILD/compile-pentium-debug script than
the preceding set of shell commands. To compile on a different
architecture, modify the script by removing flags that are
Pentium-specific, or use another script that may be more
appropriate. These scripts are provided on an
“as-is” basis. They are not officially maintained
and their contents may change from release to release.
When the build is done, run make install.
Be careful with this on a production machine; the command may
overwrite your live release installation. If you already have
MySQL installed and do not want to overwrite it, run
./configure with values for the
options different from those used for your production server.
Play hard with your new installation and try to make the new features crash. Start by running make test. See Section 22.1.2, “MySQL Test Suite”.
If you have gotten to the make stage, but
the distribution does not compile, please enter the problem
into our bugs database using the instructions given in
Section 1.7, “How to Report Bugs or Problems”. If you have installed the
latest versions of the required GNU tools, and they crash
trying to process our configuration files, please report that
also. However, if you get a
found error or a similar problem for
aclocal, configure, or
other required tools, do not report it. Instead, make sure
that all the required tools are installed and that your
PATH variable is set correctly so that your
shell can find them.
