wiki:Scripts/testport_script

testport is a Bash script to test install a specified port in a custom MacPorts location in the /opt directory.

The default location is /opt/macports-test.


#!/bin/bash

# testport  --  test install a specified port in /opt/macports-test (default)

# https://trac.macports.org/wiki/Scripts/testport_script

# 1. move the /opt/local MacPorts system to ${opt_local_off} to make sure it is not interfering with the custom ${MP_PREFIX} MacPorts build process
# 2. move /usr/local to ${usr_local_off} to make sure it is not interfering with the custom ${MP_PREFIX} MacPorts build process
# 3. install a fresh MacPorts 2.0.4 system to "${MP_PREFIX}"
# 4. install the specified port to the custom ${MP_PREFIX} MacPorts system
