Linux

The following packages must be installed to build on Ubuntu or Debian:

• libtinfo5
• build-essential
• pkg-config
• libstdc++-12-dev (depending on version, may be 10 instead of 12)
• cmake
• git

The following packages must be installed to build on EL9 or EL8:

• 'development tools' - via groupinstall
• cmake
• git

MacOS

The following packages must be install to build on MacOS:

• XCode - and the command line tools
• cmake

Building

Building plv8 needs to have all build requirements fulfilled before building. You must make sure that pg_config is in your path. It should share the same installation directory as psql and postgres.

make

Installing

This should install plv8 as an available extension into Postgres.

make install

Run Tests

Postgres features a test runner, and plv8 includes a number of tests that can be run.

make installcheck

Running

=# CREATE EXTENSION plv8;

This will install PLV8 into your database if it exists as an available extension.

Testing

To test, you can execute:

=# DO $$ plv8.elog(NOTICE, "hello there!"); $$ LANGUAGE plv8;
