Building MySQL from the source code enables you to customize build parameters, compiler optimizations, and installation location. For a list of systems on which MySQL is known to run, see https://www.mysql.com/support/supportedplatforms/database.html.
Before you proceed with an installation from source, check whether Oracle produces a precompiled binary distribution for your platform and whether it works for you. We put a great deal of effort into ensuring that our binaries are built with the best possible options for optimal performance. Instructions for installing binary distributions are available in Installing MySQL on Unix/Linux Using Generic Binaries.
If you are interested in building MySQL from a source distribution
using build options the same as or similar to those use by Oracle to
produce binary distributions on your platform, obtain a binary
distribution, unpack it, and look in the
docs/INFO_BIN file, which contains information
about how that MySQL distribution was configured and compiled.
Building MySQL with nonstandard options may lead to reduced functionality, performance, or security.
The MySQL source code contains internal documentation written using Doxygen. The generated Doxygen content is available at https://dev.mysql.com/doc/index-other.html. It is also possible to generate this content locally from a MySQL source distribution using the instructions at Generating MySQL Doxygen Documentation Content.
