If I configure perl to build as 32 bit on a 32/64 bit system:

./Configure -des -Dusedevel -Accflags=-m32 -Aldflags=-m32 -Alddlflags=-m32

the build fails. This is a re-run of make:

The problem is that the -Alddlflags happens at the wrong time relative to
everything else. Configure sets a default if none is set yet:

case "$lddlflags" in
'') case "$osname" in
beos) dflt='-nostart' ;;
haiku) dflt='-shared' ;;
hpux) dflt='-b';
case "$gccversion" in
'') dflt="$dflt +vnocompatwarnings" ;;
esac
;;

next) dflt='none' ;;
solaris) dflt='-G' ;;
sunos) dflt='-assert nodefinitions' ;;
svr4*|esix*|nonstopux) dflt="-G $ldflags" ;;
*) dflt='none' ;;
esac
;;
*) dflt="$lddlflags" ;;
esac

but because -A processing has already happened, lddlflags is already set to
something. This certainly isn't the intent of -A

Is this something common to all builds, or gcc specific?

I mean gcc is obviously used as loader on these systems, whereas on
some the hints automatically switch to ld (see hpux and solaris in the
above example). Sometimes it is a nasty cooperation with the hints.

That also re-raises the question: do we care enough to add
-Duse32bitall support? The default on most 64bit Linux distributions is
to build 64bit

This ticket sounds like the same issue as #13676. In both cases, I would bet we can just fail if someone tries to compile 32bit perl on a 64 bit system. My suspicion is that nobody would complain.

khwilliamson · 2020-04-29T00:54:43Z

One of my standard testing configurations includes
-Accflags=-m32 -Aldflags=-m32 -Alddlflags=-m32

Configure should use the ccflags and ldflags when probing for libraries. #13676
