In order to use these functions you must compile CGI or CLI PHP with
newt support by using the --with-newt[=DIR]
configure option.

You may need also curses and slang libraries, in order to compile this extension. To specify locations of these libraries, use the following configuration options: --with-curses-dir=/path/to/libcurses --with-slang-dir=/path/to/libslang
This extension uses two resource types: "newt component" and "newt grid". Resource type "newt component" is returned by functions, which create common newt widgets (for example: newt_button()) Resource type "newt grid" is a special link identifier for components, returned by newt grid factory functions (for example: newt_create_grid())
