When I compile Perl 5.005_60 on SPARC/Linux, I get many error messages
about relocations​:

cc -shared -L/usr/local/lib -o libperl.so perl.o gv.o toke.o perly.o op.o
regcomp.o dump.o util.o mg.o hv.o av.o run.o pp_hot.o sv.o pp.o scope.o
pp_ctl.o pp_sys.o doop.o doio.o regexec.o utf8.o taint.o deb.o
universal.o globals.o perlio.o

sv.o​: In function `Perl_sv_2pv'​:

Similar messages appear for Perl_sv_2bool, Perl_sv_setsv, Perl_sv_magic,
Perl_sv_rvweaken, S_sv_del_backref, Perl_sv_insert, Perl_sv_replace,
Perl_sv_clear, Perl_sv_free, Perl_sv_pos_b2u, Perl_sv_gets, Perl_sv_inc,
and many other symbols. The message finally ends with​:

make​: *** [libperl.so] Error 1

Configuration

I configured it with​:

sh Configure -Dprefix=/opt/perl -Duseshrplib -Doptimize='-g' -Uusemymalloc

and I removed POSIX from the list of extensions, because I have had
trouble building it on SPARC/Linux in the past (or I thought I had).

Other information​:

  The Linux distribution is Debian 2.1.

  $ uname -a
  Linux cx384756-a 2.0.35 #5 Wed Jul 14 09​:15​:34 EST 1999 sparc unknown

  libc='/lib/libc-2.0.105.so'

  $ cc -v
  Reading specs from /usr/lib/gcc-lib/sparc-linux/2.7.2.3/specs
  gcc version 2.7.2.3

This error also occurs if I use egcc as my compiler​:

  $ egcc -v
  Reading specs from /usr/lib/gcc-lib/sparc-linux/egcs-2.91.60/specs
  gcc version egcs-2.91.60 Debian 2.1 (egcs-1.1.1 release)

========================
Without -Doptimize='-g'​:

When I run Configure without -Doptimize='-g', I get an error when make
compiles util.c​:

`sh cflags libperl.so util.o` -fpic util.c
  CCCMD = cc -DPERL_CORE -c -Dbool=char -DHAS_BOOL
  -I/usr/local/include -O2
cc​: Internal compiler error​: program cc1 got fatal signal 6

When I use egcc in this fashion, I do not receive the fatal signal, but I
receive the relocation errors described above.

====================
Without -Duseshrplib

It seems like -Duseshrplib was the source of my troubles. Here is a
combination that works and passes most tests (POSIX works, so my fear
that it was broken, mentioned above, was unfounded)​:

  sh Configure -Dprefix=/opt/perl -Doptimize='-g' -Uusemymalloc \
  -Dcc=egcc -des

Here are the failure messages from 'make test'​:

I forgot to add that my Linux kernel was built with SMP support.

Looks like shared lib hints for Linux/SPARC need to set -fPIC rather
than -fpic.

Thanks - here is what I fed to Configure​:

It built OK, but failed a few tests​:

I think that is generic fail on _60.

lib/anydbm..........FAILED at test 12

lib/db-btree........FAILED at test 36
lib/db-hash.........FAILED at test 31

Those two are generic.
