Building and Installing PL/Perl

If the --with-perl option was supplied to the configure script, the PostgreSQL build process will attempt to build the PL/Perl shared library and install it in the PostgreSQL library directory.

Because PL/Perl is a shared library, the libperl library must be a shared library also. At the time of this writing, this is almost never the case in prebuilt Perl packages. If this difficulty arises in your situation, a message like this will appear during the build to point out this fact:

*** Cannot build PL/Perl because libperl is not a shared library. *** You might have to rebuild your Perl installation. Refer to *** the documentation for details.

If you see this, you will have to re-build and install Perl manually to be able to build PL/Perl. During the configuration process for Perl, request a shared library.

After having reinstalled Perl, change to the directory src/pl/plperl in the PostgreSQL source tree and issue the commands

make clean make all make install

to complete the build and installation of the PL/Perl shared library.

To install PL/Perl in a particular database, use the createlang script, for example createlang plperl dbname.

If a language is installed into template1, all subsequently created databases will have the language installed automatically.
