PG_CONFIG(1) PostgreSQL 9.1.9 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. 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 option --includedir-server was added in PostgreSQL 7.2. In prior releases, the server include files were installed in the same location as the client headers, which could be queried with the option --includedir. To make your package handle both cases, try the newer option first and test the exit status to see whether it succeeded. 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. In releases prior to PostgreSQL 7.1, before pg_config came to be, a method for finding the equivalent configuration information did not exist. 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. PostgreSQL 9.1.9 2013-04-01 PG_CONFIG(1)
