Perl 5.8.3 building is severely mangled on AIX. Attached are the
changes required to get a clean build and test:
- Makefile.SH
- hints/aix.sh
- config.defs
When these problems are fixed the changes should be added
to the 5.9.x tree also.
If someone can point me to the CVS info for perl 5.[89].x,
I'll do nightly builds to hopefully avoid breakage like
this in the future on AIX.
1) Makefile.SH
Several modules report requiring additional stack memory
for maximum optimization.
In hints/aix.sh change -qmaxmem=16384 to -qmaxmem=-1 so
no compilation stack limits are imposed.
This option is valid for all versions of VAC currently
supporte by IBM. Perhaps a check should be made for
pre-VAC 5.0 and add -qmaxmem=32768, or the max, whatever
that might be.
2) hints/aix.sh
Something has changed in the default AIX link processing.
It appears -bexpall is only sometimes enforced. The ld docs
state -bexpall is still the default behavior and this appears
to be a dirty, rotten lie. :-)
This occurs on later versions of AIX 433 and all versions
of 510, 520 and 520+. It's unclear whether this is a VAC
or ld problem.
Change the following in Makefile.SH to drop deprecated flags
(-H512 -T512) and add -bexpall.
aix*)
shrpldflags="-H512 -T512 -bhalt:4 -bM:SRE -bE:perl.exp"
case "$osvers" in
3*) shrpldflags="$shrpldflags -e _nostart"
;;
*) shrpldflags="-bnoentry -bexpall -bhalt:4 -bM:SRE -bE:perl.exp"
;;
esac
shrpldflags="$shrpldflags $ldflags $perllibs $cryptlib"
linklibperl="-L $archlibexp/CORE -L `pwd | sed 's/\/UU$//'` -lperl"
;;
Adding -bexpall should be okay, as it's suppose to be the default
anyway. When IBM fixes this (someday) the -bexpall will become a NOP.
3) config.defs
Here's where the majority of breakage occurs. Someone has
mangled library entry point sensing for AIX.
As a result many HAS_* and I_* constants are left commented
out. Imagine how well perl runs with HAS_PIPE and HAS_SOCKET
commented out.
See the attached config.defs file for the #defines I added
to get a clean build.
If someone can suggest a *real* fix for this, I'll try it
and report my results.
4) Configure args required for HAS_*/I_* workaround
Just setting HAS_* is insufficient for getting the extensions
Socket and IPC/SysV to build. Here's the Configure command line
which seems to get the job *** partially *** done:
bash ./Configure \
-Dprefix=/usr/local/perl-5.8.3-32bit -des -Dusedevel \
-Doptimize=-g -DDEBUGGING -Dusenm -Dusethreads -Duseshrplib \
-Dd_dosuid -Dd_socket -Dd_msg -Dd_sem -Dd_shm \
-Dbison -Dyacc='bison -y' \
-Dcf_by='http://www.davidfavor.com' \
-Dcf_email='dfavor@davidfavor.com'
This is a required workaround until library entry point sensing
is fixed.
5) bison sensing broken
-Dyacc='bison -y' must be added as bison sensing is broken also.
