Subject: Cwd 2.10 doesn't build with static Perl

Hello, I have a static version of Perl 5.8.2 compiled with -pg to run performance tests. Building Cwd 2.10 on this gets a core dump: % make cp Cwd.pm blib/lib/Cwd.pm /opt/i386-linux/installed/perl-5.8.2-g-pg/bin/perl5.8.2 /opt/i386-linux/installed/perl-5.8.2-g-pg/lib/5.8.2/ExtUtils/xsubpp

Unfortunately I have no clue what the problem is or how to fix it. Is it still broken in Cwd 2.14? -Ken

Yes, it still fails. I'll take a closer look into the core file and see what the stack trace shows. Blair

Good progress. If you change this in the Makefile: --- Makefile.orig 2004-01-14 08:57:36.000000000 -0800 +++ Makefile 2004-01-14 09:00:21.000000000 -0800 @@ -804,7 +804,7 @@ $(MAKE_APERL_FILE) : $(FIRST_MAKEFILE) $(NOECHO) $(ECHO) Writing \"$(MAKE_APERL_FILE)\" for this $(MAP_TARGET) - $(NOECHO) $(PERLRUNINST) \ + $(PERLRUNINST) \ Makefile.PL DIR= \ MAKEFILE=$(MAKE_APERL_FILE) LINKTYPE=static \ MAKEAPERL=1 NORECURS=1 CCCDLFLAGS= to see the command that generates Makefile.aperl and then run make test: Writing "Makefile.aperl" for this perl /opt/i386-linux/installed/perl-5.8.2-g-pg/bin/perl5.8.2 "- Iblib/arch" "-Iblib/lib" \ Makefile.PL DIR= \ MAKEFILE=Makefile.aperl LINKTYPE=static \ MAKEAPERL=1 NORECURS=1 CCCDLFLAGS= Attempt to free unreferenced scalar: SV 0x8616808 at blib/lib/Cwd.pm line 162. make: *** [Makefile.aperl] Segmentation fault (core dumped) Now try running the same command minus the -I's and it'll run just fine: /opt/i386-linux/installed/perl-5.8.2-g-pg/bin/perl5.8.2 \ Makefile.PL DIR= \ MAKEFILE=Makefile.aperl LINKTYPE=static \ MAKEAPERL=1 NORECURS=1 CCCDLFLAGS= Writing Makefile.aperl for Cwd In fact, trying to run perl Makefile.PL make make test with Cwd 2.08, the same version that came with perl 5.8.2 runs fine, so this just looks like a mismatch between .pm and .xs code. So we just have to make certain that Makefile.PL uses the already installed Cwd instead of the new Cwd. Blair

Hi, What happens if you use the following patch to the Makefile.PL? --- Makefile.PL 2004/01/03 04:41:52 1.9 +++ Makefile.PL 2004/01/15 02:21:02 @@ -1,7 +1,9 @@ # Note: this file was auto-generated by Module::Build::Compat version 0.03 # Generated by Module::Build::Compat->create_makefile_pl +BEGIN { @INC = grep {!/blib/} @INC } use ExtUtils::MakeMaker; WriteMakefile ( NAME => 'Cwd',

That did the trick. Works like a charm. Best, Blair
Okay, I've just uploaded version 2.15 which should fix this problem. -Ken
