Bug 33016 – emerge mod_perl shows threaded build for PERL 5.8.0-r12 with -threads

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jeff Hayes 2003-11-08 10:29:57 UTC]

ran into the problem of the mod_perl build dying without a trace and then did
env USE="-ipv6" emerge mod_perl
then it got farther .. but died when it did not find "apxs" installed.  I could 
not find out anything about what apxs is .. but in the build messages I noticed 
that it was complaining that my PERL was build threaded.  This is NOT correct 
as I ensured that i did not have "threads" in my USE var but in the output of 
the build:
 [33;01m*[0m PLEASE NOTE: If you want to compile perl-5.8 with
 [33;01m*[0m threading enabled , you must restart this emerge
 [33;01m*[0m with USE=threads emerge....

and so, after failing to install there is no error message for the user. 

Not good

Reproducible: Always
Steps to Reproduce:
1.install apache2
2.env USE="-ipv6 -threads" emerge perl mod_perl
3.

Actual Results:  
what you saw .. the emerge of PERL succeeded, but only in making a broken PERL, 
and mod_perl did not even try to build

[Comment 1 Jeff Hayes 2003-11-08 14:53:16 UTC]

umm .. i guess i should mention why this was a problem for me :-/

i want to run apache2 on this machine .. with PERL in its threaded version
I have to build apache for threads also .. which I do not want to do.  and
some of the PERL things that I use break when PERL is threaded anyway.  So
.. how does it happen that PERL is ignoring the USE flag that is supposed
to make it build as I want it to?

at this moment I cannot move my web server to the new machine as i cannot
install mod_perl .. thus the Critical rating on this bug

[Comment 2 Michael Cummings (RETIRED) 2004-02-27 13:43:33 UTC]

Posix threads (pthreads) is not the same as threading in perl. Your perl is not built with threading - says so in the output you pasted ;)

That's the first two cents. Looking at the rest.

[Comment 3 Stuart Herbert (RETIRED) 2004-04-23 01:35:23 UTC]

Another historic bug for the apache team to look at please ;-)

[Comment 4 Georgi Georgiev 2004-06-03 20:27:18 UTC]

$ perl -V | grep thread
This should show you that your perl is not threaded.

ldd /usr/bin/perl
ldd /usr/sbin/apache*

These both show linking against pthreads, which is just what the mod_perl ebuild warns about.

Since the bug is related to threaded perl, it should probably be marked as invalid?

apxs is probably the thing mentioned before the warning.

[Comment 5 Michael Cummings (RETIRED) 2004-09-04 05:53:40 UTC]

Closing because OP never made comment out after we made the distinction between perl threads and pthreads.
