In FreeBSD, the ports system is used to manage the installation and maintenance of software packages. The ports system allows you to build and install packages from source code, and includes a variety of options that can be used to customize the build process.
To reconfigure a FreeBSD port and remove the OPTIONS configuration for a port, you will need to use the make config command. make config is a command-line utility that is used to reconfigure a port and change its build options.
Here's a general outline of the steps you will need to follow to reconfigure a FreeBSD port and remove the OPTIONS configuration for a port:
Change to the directory containing the port's source files. The port's source files are usually located in the /usr/ports/ directory, in a subdirectory named after the port.
Run the make config command to reconfigure the port.
Here's an example of how to use make config to reconfigure a port called myport:
cd /usr/ports/myport make config
When the make config command is run, a menu of options will be displayed. Use the menu to navigate to the OPTIONS configuration for the port and press d to delete the OPTIONS configuration.
Once you have removed the OPTIONS configuration for the port, press Esc to exit the menu and save your changes.
It's important to note that reconfiguring a port may be necessary if you want to change the build options for the port or if you need to disable certain features or options. Consult the make config documentation and online resources for more information on how to reconfigure a FreeBSD port.
