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

So we just have to make certain that Makefile.PL uses the already installed Cwd instead of the new Cwd. Blair
