I am trying to compile a 64bit perl 5.8, using GCC 3.2 on solaris. So far
with
little success. I started with a clean perl 5.8, and ran Configure thus:
# sh Configure -Dcc=gcc -des -Duse64bitall > Configure.log 2>&1
And then I ran (gnu) make:
# /usr/local/bin/make
This ended with the following error:
<last few lines of output from make...>
`sh cflags "optimize='-O'" opmini.o` -DPERL_EXTERNAL_GLOB opmini.c
CCCMD = gcc -DPERL_CORE -c -mcpu=v9 -m64 -Wa,-xarch=v9
-fno-strict-aliasing -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -O -Wall
rm -f opmini.c
gcc -L/usr/local/lib -L/usr/lib/sparcv9 -o miniperl \
miniperlmain.o opmini.o libperl.a -lsocket -lnsl -ldl -lm -lc
ld: fatal: file miniperlmain.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to miniperl
collect2: ld returned 1 exit status
make: *** [miniperl] Error 1
<end output>
What seems to happen here is that ld complains about some of the object
files. They are 64BIT (what a surprise) but ld aparently doesn't expect
this. To find out why I ran gcc with the -v option.
# gcc -v -L/usr/local/lib -L/usr/lib/sparcv9 -o miniperl \

And the problem became clear. The collect2 seems to "collect" the wrong
modules. The modules in usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.2/ are
32BIT modules. We need to tell gcc to link against what lives in the sparcv9
subdir. Adding -m64 seems to do the trick...

See how gcc now takes the correct libraries...
I guess the hints file for solaris needs updating...
So I went back to the start and re-ran Configure with a couple of ectra
options, thus:
sh Configure -Dcc=gcc -des -Duse64bitall -Aldflags="-mcpu=v9 -m64"\
-Alddlflags="-mcpu=v9 -m64" > Configure.log 2>&1
I ran make and saw that my previous problems were aparently solved...
But then after a while this happens:

And here I am currently stuck.
Looking at the missing symbols I guess that some fundamental part of perl
isn't included in the linking. But what?
Thanks in advance,
