Could you please download the latest developer snapshot from http://www.iki.fi/jhi/cfgperl4306.tar.gz and retry with that. I have no misconceptions that the snapshot will work any better for the particular problem you describe, but any patches you supply should very preferably be against the above version. The dl_aix.xs (and other things relevant to AIX, such as building perl.exp) have changed somewhat since the 5.005_03. But, I have a slew of questions... You say "To get them to initialize properly the load and unload function calls in DynaLoader/dl_aix.xs need to be replaced with libC_r.a function calls loadAndInit and terminateAndUnload." Ummm. Will non-C++-non-statics extensions load okay, too, with the loadAndInit and terminateAndUnload, really? Just doublechecking. How are the loadAndInit() and terminateAndUnload() used? I do not have the IBM C++ compiler installed in the AIX boxes I have access to so I don't know. > #include </usr/ibmcxx/include/load.h> Ummm, not any less strange path available? Absolute paths inside the <> construct look kinda funny. > Linking with libC_r.a should not be a problem since it is > shipped with base AIX. Since AIX version 3? (Yeah, I guess it's no more supported...but still.) Since AIX version 4.something? If the loadAndInit() and terminateAndUnload() are not available in *all* versions of AIX then we have problem: we need to be able to detect whether we have them (we can do this in hints/aix.sh, if need be). And which one does need to be linked with -lC_r? Perl itself? Or just the Dynaloader extension? Don't get me wrong: while I'm rather wary above, I appreciate your detective work. But we need (a) backward compatibility and (b) clean fixes, and to get these, I need answers to my above doubts... While the above snapshot is from the development strain leading into Perl 5.6 (the next major release) and as such probably not 100% applicable to the 5.005 branch, the goal is to backport most of the enhancements from 5.6 back to the 5.005. Fixing dynaloading is definitely something that should be backported. -- $jhi++; # http://www.iki.fi/jhi/ # There is this special biologist word we use for 'stable'. # It is 'dead'. -- Jack CohenThread Previous
