PG_CONFIG(1)		PostgreSQL 9.6.3 Documentation		  PG_CONFIG(1)

NAME
       pg_config - retrieve information	about the installed version of
       PostgreSQL

SYNOPSIS
       pg_config [option...]

DESCRIPTION
       The pg_config utility prints configuration parameters of	the currently
       installed version of PostgreSQL.	It is intended,	for example, to	be
       used by software	packages that want to interface	to PostgreSQL to
       facilitate finding the required header files and	libraries.

OPTIONS
       To use pg_config, supply	one or more of the following options:

       --bindir
	   Print the location of user executables. Use this, for example, to
	   find	the psql program. This is normally also	the location where the
	   pg_config program resides.

       --docdir
	   Print the location of documentation files.

       --htmldir
	   Print the location of HTML documentation files.

       --includedir
	   Print the location of C header files	of the client interfaces.

       --pkgincludedir
	   Print the location of other C header	files.

       --includedir-server
	   Print the location of C header files	for server programming.

       --libdir
	   Print the location of object	code libraries.

       --pkglibdir
	   Print the location of dynamically loadable modules, or where	the
	   server would	search for them. (Other	architecture-dependent data
	   files might also be installed in this directory.)

       --localedir
	   Print the location of locale	support	files. (This will be an	empty
	   string if locale support was	not configured when PostgreSQL was
	   built.)

       --mandir
	   Print the location of manual	pages.

       --sharedir
	   Print the location of architecture-independent support files.

       --sysconfdir
	   Print the location of system-wide configuration files.

       --pgxs
	   Print the location of extension makefiles.

       --configure
	   Print the options that were given to	the configure script when
	   PostgreSQL was configured for building. This	can be used to
	   reproduce the identical configuration, or to	find out with what
	   options a binary package was	built. (Note however that binary
	   packages often contain vendor-specific custom patches.) See also
	   the examples	below.

       --cc
	   Print the value of the CC variable that was used for	building
	   PostgreSQL. This shows the C	compiler used.

       --cppflags
	   Print the value of the CPPFLAGS variable that was used for building
	   PostgreSQL. This shows C compiler switches needed at	preprocessing
	   time	(typically, -I switches).

       --cflags
	   Print the value of the CFLAGS variable that was used	for building
	   PostgreSQL. This shows C compiler switches.

       --cflags_sl
	   Print the value of the CFLAGS_SL variable that was used for
	   building PostgreSQL.	This shows extra C compiler switches used for
	   building shared libraries.

       --ldflags
	   Print the value of the LDFLAGS variable that	was used for building
	   PostgreSQL. This shows linker switches.

       --ldflags_ex
	   Print the value of the LDFLAGS_EX variable that was used for
	   building PostgreSQL.	This shows linker switches used	for building
	   executables only.

       --ldflags_sl
	   Print the value of the LDFLAGS_SL variable that was used for
	   building PostgreSQL.	This shows linker switches used	for building
	   shared libraries only.

       --libs
	   Print the value of the LIBS variable	that was used for building
	   PostgreSQL. This normally contains -l switches for external
	   libraries linked into PostgreSQL.

       --version
	   Print the version of	PostgreSQL.

       -?
       --help
	   Show	help about pg_config command line arguments, and exit.
       If more than one	option is given, the information is printed in that
       order, one item per line. If no options are given, all available
       information is printed, with labels.

NOTES
       The options --docdir, --pkgincludedir, --localedir, --mandir,
       --sharedir, --sysconfdir, --cc, --cppflags, --cflags, --cflags_sl,
       --ldflags, --ldflags_sl,	and --libs were	added in PostgreSQL 8.1. The
       option --htmldir	was added in PostgreSQL	8.4. The option	--ldflags_ex
       was added in PostgreSQL 9.0.

EXAMPLE
       To reproduce the	build configuration of the current PostgreSQL
       installation, run the following command:

	   eval	./configure `pg_config --configure`

       The output of pg_config --configure contains shell quotation marks so
       arguments with spaces are represented correctly.	Therefore, using eval
       is required for proper results.
