Perl 5.8 not built with threading support

[triddle@…]

The current Perl 5.8 port does not support threading however the Apple supplied Perl 5.8 does. I think that the Macports install of Perl in this instance should match the features of the vendor supplied perl. Is it possible to update the compile flags so the 5.6 threading model (ithreads) is supported?

Here is the difference between Macports perl and the Apple supplied perl:

Foodmotron:~ tyler$ echo "use threads;" | /usr/bin/perl #expected result
Foodmotron:~ tyler$ echo "use threads;" | /opt/local/bin/perl #unexpected result
This Perl not built to support threads
Compilation failed in require at - line 1.
BEGIN failed--compilation aborted at - line 1.

This is true for Leopard and Snow Leopard at this time.

You need to install with the +threads variant. In your case you can upgrade to it.

sudo port upgrade perl5.8 +threads

I think that original reported is right, Perl must be installed using the same configuration as the one from Apple. This is not something nice to have, failing to do this will break lots of applications.

Replying to sorin.sbarnea@…:

failing to do this will break lots of applications.

how? Do you have examples of anything that is actually broken?

Apple-provided perl is still there.
