Yes, I know and already complained at p5p, because I tought they removed the public A flag from embed.fnc. But it never was as Nick recently told me, so B::Generate always was wrong using this API. I just disabled some time ago it for known strict linkers: cygwin and mingw. So somebody (me or you :)) has to send a p5p patch to export the needed core functions - here are more, not only this - together with API docs and test case. -- Reini Urban http://phpwiki.org/ http://murbreak.at/

Hi Reini, If you remember, I DID send a patch in, looong time ago: http://rt.perl.org/rt3//Public/Bug/Display.html?id=56536 I'm just, well, don't know what else I can do. If Nicholas is unpingable,then... what?

Ah, I remember now. Show quoted text

The problem is not the flag itself. The problem is the missing core documentation and testcases. And as Rafael already said, maybe pad_alloc() should be changed. From my POV p5p should now change it and leave then B::Generate work as expected. B::Generate is one of the rare modules which are mentioned in the core pods. -- Reini Urban http://phpwiki.org/ http://murbreak.at/

According to Slaven's check http://gist.github.com/347647 fold_constants() also fails since Nick made it static with in b7783a124 Author: Nicholas Clark <nick@ccl4.org> Date: Wed Nov 26 19:36:06 2008 +0000 for AutoXS, Amb, Code::Splice

Hi again, I'm just thinking, if core- is so reluctant to open these functions, maybe you could just copy-paste them into Generate.xs, and that's it? I've seen that many modules do so. /dk

Yes, will do. And I will prepare the p5p patches also, just not this month. -- Reini

I've added Perl_pad_alloc, Perl_cv_clone and fold_constants detections to the installer, and a pad_alloc re-implementation to the module. Since 1.3201. The others two functions are purely optional. -- Reini Urban
