Re^4: Bareword "threads::joinable" not allowed while "strict subs" in use

[lifang11]

Thanks for all above!

The perl is too old,but update is too difficult to achieve.

I have 20+ machines and 3+ projects running more than 3+ years.

I don't know the result after update perl.

This must be new code otherwise you wouldn't only now be discovering that threads::joinable isn't available.

So, why not install a new version in parallel and run your new code on that?

---

Your sample code does nothing useful, so I cannot safely advise how to re-write it so that you do not need joinable; but if your threads are not returning anything, why join them at all?

You could just detach them and let them go away naturally; but then you need to have a mechanism for deciding when your main thread can end.

Alternatively; why test for joinable? Most of the time you want to wait for them all to end; so a simple:

$_->join for @threads;

Is all that is required.

But again, given silly sample code, it is impossible to advise which strategy makes sense in your case.

"I don't know the result after update perl."

Sounds like a situation I was in. Install your own perl elsewhere on your system, test your apps against the new version.
