RE:PostgreSQL 11 beta1 on AIX 7.2 : 2 failures in 32bit mode - Mailing list pgsql-hackers

Hi Tom,

Here are information about the Perl version we are using on our AIX 7.2 machine.

However, as I said already, all PostgreSQL tests of v10.4 and 9.6.9 are OK, both 32 and 64bit.



# rpm -qa | grep perl
perl-5.24.0-3

This version 5.24.0 release 3 of Perl has been built on a AIX 6.1 machine (everything built on AIX 6.1 is compatible
withAIX 7). 

Looking at the log of the build/tests, I see:
32bit: Failed 1 test out of 2308, 99.96% okay.     t/porting/podcheck ............................................
FAILEDat test 1 
64bit: All tests successful.

We still build perl with XLC (v13.1.3) since we still have issues with GCC. Now trying to build 5.26.2 with GCC.


Running the following recommended command in 32 bit:
    setenv LIBPATH `pwd`:$LIBPATH; cd t; ./perl harness
I have:

About the libperl, I have:
# ar tv /opt/freeware/lib/perl5/5.24.0/ppc-aix-thread-multi/CORE/libperl.a
rwxr-xr-x     0/0     2245620 Nov 14 07:37 2017 libperl.o


About Perl header files, they are provided in 2 different directories:
64bit: /opt/freeware/lib/perl5/5.24.0/ppc-aix-thread-multi-64all/CORE/
32bit: /opt/freeware/lib/perl5/5.24.0/ppc-aix-thread-multi/CORE/

One file appears once: /opt/freeware/lib/perl5/5.24.0/Encode/encode.h , but is not used by PostgreSQL.

# diff /opt/freeware/lib/perl5/5.24.0/ppc-aix-thread-multi/CORE/perl.h
/opt/freeware/lib/perl5/5.24.0/ppc-aix-thread-multi-64all/CORE/perl.h
# identical

The Perl header files are coherent with libperl.a I think.

Seems so, but why?  The code involved doesn't look very machine-dependent.

I'm wondering about some sort of version skew or misinstallation on
the Perl side --- say, header files that we're using to compile
that don't match the libperl.so used at runtime.
