AlpmDepMissing

AlpmDepMissing

Describes an unsatisfied dependency found while preparing a transaction. You don't construct this yourself — it shows up in AlpmTransaction::prepare()'s return value when errno is ALPM_ERR_UNSATISFIED_DEPS:

$err = $trans->prepare();
if ($err !== null && !empty($err["offenders"])) {
    foreach ($err["offenders"] as $missing) {
        if ($missing instanceof AlpmDepMissing) {
            echo "{$missing->target} needs {$missing->depend}\n";
        }
    }
}

See AlpmTransaction for the full prepare() error shape.
