I’m trying to go through the steps needed to internationalize (i18n) my wordpress plugins. So far I’ve hit alot of stumbling blocks:

• the __() PHP function keeps giving me the error "[error] PHP Fatal error:  Call to undefined function __()" even though I have called load_plugin_textdomain(). From looking at other plugins, I don’t see any require_onces/includes that I am missing. Better looker harder I guess.
• the makepot.php on the wordpress.org site says generates an error because it tries to do “require_once ‘not-gettexted.php’;” . But, not-gettexted.php does not exist. If I comment that out it fails with another strange error:

Warning: fopen(./wordpress/wp-content/plugins/popupper-v10/popupper-v10.php): failed to open stream: No such file or directory in ./makepot.php on line 136
xgettext: unrecognized option `--package-name='
Try `xgettext --help' for more information.
Couldn't generate POT file!

Guess I’ll keep on plodding…
