Hello, right now it looks like Perl 5.8.9 RC1 (and 5.10.x / bleed) does not compiler with gcc on AIX. I already have submitted a patch for bleed (34983). With this patch applied to 5.8.9 RC1 you can compile: Perl 5.8.9 RC1 with gcc 3.3.2 Perl 5.8.9 RC1 with gcc 4.2.4 Perl 5.8.9 RC1 with IBM C/C++ V7 Perl 5.8.9 RC1 with IBM C/C++ V8 Perl 5.8.9 RC1 with IBM C/C++ V9 Perl 5.8.9 RC1 with IBM C/C++ V10 I have tested this on AIX 5.1 / 5.2 / 5.3 / 6.1 (not with all compiler combinations :-) ). Settings: -Duseshrplib (I think this is mandatory) -Dusethreads (Optional) So if there are no objections in the next couple of day I vote to include this patch in 5.8.9. If you think that the change to Makefile.SH is to sensitive for 5.8.9 then we have to change the README.aix and remove gcc from the supported compiler list. A other problem is suidperl: To make this work on AIX we need a other patch to makefile.SH: This patch adds the libperl_nonshr.a in front of libperl.a for AIX (libperl.a is only used for the Dynloader). Without the patch suidperl simply wont compile/work on AIX and with the patch suidperl is linked statically with the exception of the Dynloader. Should this be fixed for 5.8.9 or should we fix it for 5.10.x / bleed ?? Bye RainerThread Next
