PostgreSQL

GNU make version 3.81 or newer is required; other make programs or older GNU make versions will not work. (GNU make is sometimes installed under the name gmake.) To test for GNU make enter:

make --version

You need an ISO/ANSI C compiler (at least C99-compliant). Recent versions of GCC are recommended, but PostgreSQL is known to build using a wide variety of compilers from different vendors.

tar is required to unpack the source distribution, in addition to either gzip or bzip2.

The GNU Readline library is used by default. It allows psql (the PostgreSQL command line SQL interpreter) to remember each command you type, and allows you to use arrow keys to recall and edit previous commands. This is very helpful and is strongly recommended. If you don’t want to use it then you must specify the --without-readline option to configure. As an alternative, you can often use the BSD-licensed libedit library, originally developed on NetBSD. The libedit library is GNU Readline-compatible and is used if libreadline is not found, or if --with-libedit-preferred is used as an option to configure. If you are using a package-based Linux distribution, be aware that you need both the readline and readline-devel packages, if those are separate in your distribution.

The zlib compression library is used by default. If you don’t want to use it then you must specify the --without-zlib option to configure. Using this option disables support for compressed archives in pg_dump and pg_restore.

To build the server programming language PL/Perl you need a full Perl installation, including the libperl library and the header files. The minimum required version is Perl 5.8.3. Since PL/Perl will be a shared library, the libperl library must be a shared library also on most platforms. This appears to be the default in recent Perl versions, but it was not in earlier versions, and in any case it is the choice of whomever installed Perl at your site. configure will fail if building PL/Perl is selected but it cannot find a shared libperl. In that case, you will have to rebuild and install Perl manually to be able to build PL/Perl. During the configuration process for Perl, request a shared library.

To build the PL/Python server programming language, you need a Python installation with the header files and the sysconfig module. The minimum required version is Python 3.2.

To build the PL/Tcl procedural language, you of course need a Tcl installation. The minimum required version is Tcl 8.4.

To enable Native Language Support (NLS), that is, the ability to display a program’s messages in a language other than English, you need an implementation of the Gettext API. Some operating systems have this built-in (e.g., Linux, NetBSD, Solaris), for other systems you can download an add-on package from https://www.gnu.org/software/gettext/. If you are using the Gettext implementation in the GNU C library then you will additionally need the GNU Gettext package for some utility programs. For any of the other implementations you will not need it.

You need OpenSSL, if you want to support encrypted client connections. OpenSSL is also required for random number generation on platforms that do not have /dev/urandom (except Windows). The minimum required version is 1.0.1.

You need Kerberos, OpenLDAP, and/or PAM, if you want to support authentication using those services.

You need LZ4, if you want to support compression of data with that method; see default_toast_compression and wal_compression.

You need Zstandard, if you want to support compression of data with that method; see wal_compression. The minimum required version is 1.4.0.

To build the PostgreSQL documentation, there is a separate set of requirements; see Section J.2.

Flex and Bison are needed to build from a Git checkout, or if you changed the actual scanner and parser definition files. If you need them, be sure to get Flex 2.5.31 or later and Bison 1.875 or later. Other lex and yacc programs cannot be used.

Perl 5.8.3 or later is needed to build from a Git checkout, or if you changed the input files for any of the build steps that use Perl scripts. If building on Windows you will need Perl in any case. Perl is also required to run some test suites.
