pg_config

Retrieves information about the installed version of LightDB-A Database.

Synopsis

pg_config [<option> ...]

pg_config -? | --help

pg_config --version

Description

The pg_config utility prints configuration parameters of the currently installed version of LightDB-A Database. It is intended, for example, to be used by software packages that want to interface to LightDB-A Database to facilitate finding the required header files and libraries. Note that information printed out by pg_config is for the LightDB-A Database 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 LightDB-A Database was configured for building.

–cc : Print the value of the CC variable that was used for building LightDB-A Database. This shows the C compiler used.

–cppflags : Print the value of the CPPFLAGS variable that was used for building LightDB-A Database. This shows C compiler switches needed at preprocessing time.

–cflags : Print the value of the CFLAGS variable that was used for building LightDB-A Database. This shows C compiler switches.

–cflags_sl : Print the value of the CFLAGS_SL variable that was used for building LightDB-A Database. This shows extra C compiler switches used for building shared libraries.

–ldflags : Print the value of the LDFLAGS variable that was used for building LightDB-A Database. This shows linker switches.

–ldflags_ex : Print the value of the LDFLAGS_EX variable that was used for building LightDB-A Database. 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 LightDB-A Database. This shows linker switches used for building shared libraries only.

–libs : Print the value of the LIBS variable that was used for building LightDB-A Database. This normally contains -l switches for external libraries linked into LightDB-A Database.

–version : Print the version of LightDB-A Database.

Examples

To reproduce the build configuration of the current LightDB-A Database 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.
