pg_config

Retrieves information about the installed version of WarehousePG.

Synopsis

pg_config [<option> ...]

pg_config -? | --help

pg_config --gp_version

Description

The pg_config utility prints configuration parameters of the currently installed version of WarehousePG. It is intended, for example, to be used by software packages that want to interface to WarehousePG to facilitate finding the required header files and libraries. Note that information printed out by pg_config is for the WarehousePG coordinator only.

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.

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.

--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 may also be installed in this directory.)

--localedir Print the location of locale support files.

--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 WarehousePG was configured for building.

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

--cppflags Print the value of the CPPFLAGS variable that was used for building WarehousePG. This shows C compiler switches needed at preprocessing time.

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

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

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

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

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

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

--version Print the version of PostgreSQL backend server.

--gp_version Print the version of WarehousePG.

Examples

To reproduce the build configuration of the current WarehousePG 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.
