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 Greenplum Database was configured for building.

--cc=>Print the value of the CC variable that was used for building Greenplum Database. This shows the C compiler used.

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

--cflags=>Print the value of the CFLAGS variable that was used for building Greenplum Database. This shows C compiler switches.

--cflags_sl=>Print the value of the CFLAGS_SL variable that was used for building Greenplum 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 Greenplum Database. This shows linker switches.

--ldflags_sl=>Print the value of the LDFLAGS_SL variable that was used for building Greenplum Database. This shows linker switches used for building shared libraries.

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

--version=>Print the version of Greenplum Database.
