[Solved] Installing AGE PG16 beside Postgresql v16beta1 giving bison is missing while it is not – Postgresql

The Problem:

Installing AGE PG16 alongside Postgresql v16beta1 leads to an error indicating that ‘bison’ is missing, despite having it installed. After disabling ICU support with ‘–without-icu’ during Postgresql installation, the error persists and prevents successful AGE PG16 installation.

The Solutions:

Solution 1: Upgrade Bison

The installation of AGE PG16 beside Postgresql v16beta1 failed due to a mismatch in the Bison version. Postgresql v16beta1 requires a newer version of Bison than the one installed on your system. To resolve this issue, update Bison to the latest version using the following steps:

• Run the following command:

sudo apt-get install bison

• Verify that Bison has been updated to the latest version:

bison --version

• Re-run the AGE PG16 installation process after updating Bison.

Solution 2: Install pkg-config

To resolve the issue where AGE PG16 installation reports ‘bison’ is missing while it is not, you need to install pkg-config, which is a tool that helps find and configure libraries on your system. On Ubuntu Linux, you can install pkg-config using the following command:

“`bash
apt-get install pkgconf
“`

Solution 3: Installing the Missing Dependencies

The error indicates that bison, a program for generating parsers, is missing during the installation of AGE PG16. Despite having bison installed, the system might not be able to locate it properly. To resolve this issue:

• Update the system repositories using:

sudo apt-get update

• Install bison explicitly:

sudo apt-get install bison

This should ensure that the necessary dependencies are available and the installation of AGE PG16 can proceed successfully.
