configuration options for local perl install with threads

tphyahoo has asked for the wisdom of the Perl Monks concerning the following question:

Every so often I install perl locally, using more or less the folllowing thread, minus the -Duseithreads bit.

Now I want to compile perl with threads, so the -Duseithreads bit is in there. But doesn't work. I've tried this a couple ways: -Dusethreads and -Duseithreads. It compiles, but when I try to use it with threads, it says I didn't compile it with threads. After like half an hour of churning.

What am I doing wrong? Am I not supposed to repeat the "-D" bit (right now I have it twice, once for specifying the local directory, once for the ithreads bit).

Also, is there a difference between -Dusethreads and -Duseithreads?


angebote@debian:/usr/angebote/thartman$ cat install-local-threaded-per ( wget +r.gz tar -xzvf perl-5.8.8.tar.gz cd perl-5.8.8 sh Configure -Dprefix=/usr/angebote/thartman/perlroot/perl -Duseithrea +ds -des #make this your home directory make test make install ) | tee perlinstall.out angebote@debian:/usr/angebote/thartman$

    Your compile options look okay. Your execution errors imply that you are either using the wrong executable or trying to invove threads incorrectly. Does the following work for you:
    /usr/angebote/thartman/perlroot/perl/bin/perl -e 'use ithreads'

    To answer your question regarding the difference between -Dusethreads and -Duseithreads---there is no -Duseithreads. According to the INSTALL doc:

    "By default, Configure selects ithreads if -Dusethreads is specified".

    As for the next question, you didn't compile it with threads because you used -Duseithreads when you should have used -Dusethreads.

      Er, no. -Duseithreads is effectively a synonym for -Dusethreads.
