Custom php functions in Laravel Queues - php

Question

I am using Laravel Queues with beanstalkd. I have following code:
$user_id = Auth::user()->id;
Queue::push(function($job)
{
solve_simplex();
$job->delete();
});
where solve_simplex() is my custom function in php added as extension.
The job is queued all right but when I want to run php artisan queue:work it ends up with:
php artisan queue:work
PHP Fatal error: Call to undefined function solve_simplex() in /var/www/my_site/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(99) : eval()'d code on line 2

UPDATE
it looks like my extension is not loaded. But it does not load only in that closure. If I run the function solve_simpex() in normal laravel code (eg in controller then it works and extension is loaded....

Answer 1

I found a solution. The problem is that superclosure is invoked throught command:
php artisan queue:work
it is invoked through CLI and idk why it does not load extension.
Solution is run artisan with -d parameter:
php -dextension=solveSimplex.so artisan queue:work
So I had to tell php CLI to load that extension...
