Hi everybody

I'm trying to compile DBI-1.643 on AIX 7.3 TL2 SP2 with the newest IBM openxlC Compiler Version 17.1.2. Perl is on the following version:

perl -v

This is perl 5, version 34, subversion 1 (v5.34.1) built for aix-thread-multi

perl Makefile.PL runs through without special errors but when I try to compile I'm getting the following error:

Running Mkbootstrap for DBI ()
        chmod 644 "DBI.bs"
         "/usr/bin/perl" -MExtUtils::Command::MM -e 'cp_nonempty' -- DBI.bs blib/arch/auto/DBI/DBI.bs 644
        xlc_r -q32 -c    -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -qlanglvl=extc99 -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -q32 -D_LARGE_FILES -O    -DVERSION=\"1.643\"  -DXS_VERSION=\"1.643\"  "-I/usr/opt/perl5/lib/5.34.1/aix-thread-multi/CORE"   Perl.c

make: The error code from the last command is 41.

Stop.

I updated the Makefile and replaced the following entry:

CC = xlc_r -q32

with

CC = ibm_clang_r -q32

and get the following error while doing the make again:

Running Mkbootstrap for DBI ()
        chmod 644 "DBI.bs"
         "/usr/bin/perl" -MExtUtils::Command::MM -e 'cp_nonempty' -- DBI.bs blib/arch/auto/DBI/DBI.bs 644

.ibm-clang: error: unknown argument: '-q32'
make: The error code from the last command is 1.

So it seems I need to update the options to be clang compatible, but unfortunately I'm not really a programmer nor an expert with this kind of stuff.
Can somebody help me out or give me some clues on howto approach this ?

Thanks in advance and kind regards,

Hi Stefano,

why do you want to build it with Open XL C compiler? I understand, it is modern. But your Perl is built using Classic XL C compiler and if you build modules using new OpenXL C compiler, which is based on completely different technology, you may get other compatibility problems. You would need first rebuild Perl with OpenXL and then all other modules.

As far as I see you have the classic XL C/C++ compiler V16.1 installed on your system, but it doesn't work. The reason for that is missing fix pack. The support for AIX 7.3 was added in FP10, the latest is FP18. You can find more info here. It would be an easier solution for your problem.

If you still want to use OpenXL C/C++ compiler 17.1.2, IBM has migration guide where they describe which options were abandoned or changed and what you should use instead.

Hi Andrey

Thanks for taking the time to look into my question and answer it . I was always under the impression that we had to use the latest Compiler available when upgrading AIX to a new major release (7.2 to 7.3), so that's why I tired to use the new OpenxlC n17.1.x. I downloaded the FixPack you mentioned and was able to compile the DBI just fine now.

Thanks again and kind regards,

Stefano Calisto
