mod_perl2 build fails with perl5.10 or perl5.12 without +threads

More information would be helpful. Please attach the complete debug log.

run as port -d install mod_perl2

I'm attached complete debug log.

I see several other reports of this problem by searching Google. mod_perl2 @2.0.4 is apparently not compatible with perl5.10 (which I see you're using) or perl5.12. Use perl5.8 instead.

[jagerman@…]

The fix is trivial: look for "5.8*" in the Portfile and change it to "5.*". Doing that makes mod_perl build and work with 5.10/5.12 (tested with 5.12, but should also work with 5.10).

Nope. Just tried that fix with 5.10, same error. In fact, I can't see how that fix would help anyway, as the only reference to "5.8*" is in post-destroot. The build never reaches that far, because it dies during the compile phase.

perl5.10 portfile diff (disables multiplicity)

mod_perl2 post-destroot fix

related thread on the perl dev list: ​http://www.mail-archive.com/dev@perl.apache.org/msg12588.html disabling usemultiplicity and fixing the destroot makes this work, fwiw. patches attached. (caveat: i have no idea what multiplicity does - there seems to be very little documentation on this option)

[michael@…]

It looks like all you need to do is rebuild perl5.10 or perl5.12 using the "threads" variant.

mod_perl mistakenly assumes the MULTIPLICITY feature implies the USE_ITHREADS feature, which is not true and won't be fixed upstream for some time.

The maintainer is advised to check whether USE_ITHREADS is defined in the output of "perl -V" and abort the build early if not present, with a helpful message to the user explaining what to do.

My experience was that you have to do all of the following to get things working:

• (Re)install perl5.12 with the +threads variant.
• port clean mod_perl2 port (or it will keep looking for old files).
• Edit the Portfile for mod_perl2 to change 5.8* to 5.* in the post-destroot section.

I can confirm that this also works for me (finally!).

After patching with ​mod_perl2-portfile.diff:
build succeeds
but activate collides with p5-apache-test on ${prefix}/share/man/man3/Apache::Test.3pm.gz

--->  Activating mod_perl2 @2.0.4_0
Error: Target org.macports.activate returned: Image error: /opt/macports-test/share/man/man3/Apache::Test.3pm.gz is being used by the active p5-apache-test port.

[jon.hermansen@…]

Especially now, with the default_variant for perl5 being 5.12, I think that we should make this change to mod_perl2.

The patch is working for me, latest apache2 and perl5.12, both universal.

Adding the perl maintainer to cc since there are changes to it proposed here.

[jmroot (Joshua Root)]

BTW the mod_perl2 destroot issue is already fixed; that was #23608.

I can confirm that the current port (where the patch above is already applied) and perl5.14 with +threads will work. As I switched to Perl 5.14 I've had to rebuild all perl packages listed with port dependents perl5. I don't know if switching to the +threads variant alone also requires rebuilding?
