# This file has been put together by Anno Siegel , # Andreas Koenig and Gerd Knops . # Comments, questions, and improvements welcome! # # These hints work for NeXT 3.2 and 3.3. 3.0 has it's own # special hint file. # ###################################################################### # THE MALLOC STORY ###################################################################### # 1994: # the simple program `for ($i=1;$i<38771;$i++){$t{$i}=123}' fails # with Larry's malloc on NS 3.2 due to broken sbrk() # # setting usemymalloc='n' was the solution back then. Later came # reports that perl would run unstable on 3.2: # # 1996: # From about perl5.002beta1h perl became unstable on the # NeXT. Intermittent coredumps were frequent on 3.2 OS. There were # reports, that the developer version of 3.3 didn't have problems, so it # seemed pretty obvious that we had to work around an malloc bug in 3.2. # This hints file reflects a patch to perl5.002_01 that introduces a # home made sbrk routine (remember, NeXT's sbrk _never_ worked). This # sbrk makes it possible to run perl with its own malloc. Thanks to # Ilya who showed me the way to his sbrk for OS/2!! # # The whole malloc desaster lead to a failing gdbm test. It is far # beyond my understanding, why GDBM_File breaks with the "fix", but in # general I consider it better to have a working perl with broken GDBM # than no perl at all. # # So, this hintsfile is using perl's malloc. If you want to turn # perl's malloc off, you need to remove '-DUSE_PERL_SBRK' and # '-DHIDEMYMALLOC' from the ccflags and set usemymalloc to 'n'. # # 1997: # From perl5.003_22 the malloc bug has no impact any more. We can run # a perl without a special sbrk. Apparently Chip Salzenberg, the hero # of 5.004 anyway, earned another trophy during Australien Open. # # use the following two lines to enable USE_PERL_SBRK. Try this if you # encounter intermittent core dumps: #ccflags='-DUSE_NEXT_CTYPE -DUSE_PERL_SBRK -DHIDEMYMALLOC' #usemymalloc='y' # use the following two lines if you have perl5.003_22 or better and # do not encounter intermittent core dumps. ccflags='-DUSE_NEXT_CTYPE' usemymalloc='n' ###################################################################### # End of the MALLOC story ###################################################################### ldflags='-u libsys_s' libswanted='dbm gdbm db' lddlflags='-nostdlib -r' # Give cccdlflags an empty value since Configure will detect we are # using GNU cc and try to specify -fpic for cccdlflags. cccdlflags=' ' # # Change the line below if you do not want to build 'quad-fat' # binaries # archs=`/bin/lipo -info /usr/lib/libm.a | sed 's/^[^:]*:[^:]*: //'` for d in $archs do mab="$mab -arch $d" done archname='next-fat' ld='cc' i_utime='undef' groupstype='int' direntrytype='struct direct' d_strcoll='undef' d_uname='define' # setpgid() is in the posix library, but we don't use -posix, so # we don't see it. ext/POSIX/POSIX.xs *does* use -posix, so # setpgid is still available as POSIX::setpgid. # See ext/POSIX/POSIX/hints/next.pl. d_setpgid='undef' d_setsid='define' d_tcgetpgrp='define' d_tcsetpgrp='define' # # On some NeXT machines, the timestamp put by ranlib is not correct, and # this may cause useless recompiles.
