Mac Forum / Programming / Perl / November 2003

FWIW I get the same results as Chris with 5.8.2 and have used the
build configuration as Apple recommended for _Jaguar_ and 5.8.  So
maybe this is the problem in my case at least -- might explain my
problems with with Tk also perhaps.

Can you please post the parameters I should use with Configure.

(For the porters: the bug is that this:

    % perl -le '$^E = -1728; print $^E+0 for 0,1'

Should return this:

    -1728
    -1728

But in some cases, returns this:

    -1728
    22

Odd.)

I am building with the defaults, not with anything in particular.

Differences I see off the bat:

    usethreads
    useithreads
    usemultiplicity
    -g for ccflags
    ld (though mine is right, RC3's is wrong, I believe)
    useshrplib (though I did it both ways, with and without)

Using your exact config_args from RC3, I get the proper values.  Lessee ...
I know it is not -g or useshrplib.  Trying with only '-ds -e
-Duseithreads': yep, now I get the proper values.  But I don't want threads.

But trying to dig deeper, I'll try enabling usemultiplicity on its own:
nope, that gives me the same bug.

So, it looks like if I turn on ithreads, it is fine.  If not, it isn't.  I
have no idea WHY it would be the case, and I really wish it weren't, as I
really don't want to have threads, if I can avoid it (unless I am just
being ignorant: last I heard, a threaded perl still had trouble with
mod_perl).  But there's gotta be a bug here, regardless.

Anyone, a little help?  :)
