From: Charly <charly [...] oac.uncor.edu>
Hi, I've installed Math-Cephes-0.47 on a MacBook (OS X 10.7.2). When I do 'make test' I get: PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/99pod.t ............ ok t/bessels.t .......... 1/27 and the Mac stays there forever. I also noted this suspicious line after the 'make' command: /usr/bin/ranlib: archive library: libmd.a will be fat and ar(1) will not be able to operate on it Thanks charly

Hi charly, sorry for the late response, but I've only started maintaining this module today (taking over from the late Randy Kobes). On Fri Jan 20 07:33:39 2012, charly@oac.uncor.edu wrote: Show quoted text

Can you try again with the tip of https://github.com/shlomif/Math-Cephes ? Regards, -- Shlomi Fish

Subject: hangs on big endian machines
I have been running a smoker on a PA-RISC machine for a while, and I've had to kill it for Math::Cephes a number of times since it hangs on the first test. It looks like this RT is the same issue. perl -Iblib/lib -Iblib/arch t/bessels.t 1..27 ok 1 ok 2 not ok 3 (expected 0.1670246643: got -1212138.37621912) at t/bessels.t line 34 ok 4 not ok 5 (expected 0.06683312418: got -349717.012947448) at t/bessels.t line 36 ok 6 not ok 7 (expected 0.151169768: got -1097075.55958296) at t/bessels.t line 38 at which point it hangs forever (hence no failure report). I got the latest code from the git repo and there is no change. This is a big endian machine (which is why I'm running the smoker on it). The debugger (compiling with -g) indicates it's stuck in a loop in floor.c line 339. If I go in by hand and change mconf.h to set MIEEE 1 and BIGENDIAN 1, it no longer hangs, but on the other hand it also fails most of the tests. Sorry I don't have a nice patch, but let me know if you want me to run anything else.

There's a way to do it automatically I'm sure. Show quoted text

well, I guess I could try using QEmu or something, but I really would like that you investigate the problem and look into it. Regards, — Shlomi Fish

Certainly, but I was running the smoker to help find issues like this. I suppose now that we've narrowed down the problem I can turn off smoking it for that machine. Show quoted text

I'll see if I can. I don't actually need to run Math::Cephes right now, but it would be nice to get it working.

Marking as "stalled" due to difficulty in reproducing and lack of general interest in this bug. Show quoted text
