IMO: wrong. If there is just the runtime dependency as it seems to be in perl, then there is no need to link against libgdbm. > If I'm right, then I'm confused as to how Perl built properly -- unless > perl uses libtool for linking (in which case intrinsic deps are handled > by libtool automatically via the .la mechanism) No libtool needed for perl. I changed the hints/cygwin.pl entries since the symbols needed were not available in libgdbm.dll.a: --- perl-5.8.0/ext/NDBM_File/hints/cygwin.pl~ 2003-03-30 13:47:19.000000000 +0200 +++ perl-5.8.0/ext/NDBM_File/hints/cygwin.pl 2003-03-30 13:47:19.000000000 +0200 @@ -1,2 +1,2 @@ # uses GDBM ndbm compatibility feature -$self->{LIBS} = ['-lgdbm']; +$self->{LIBS} = ['-lgdbm_compat']; --- perl-5.8.0/ext/ODBM_File/hints/cygwin.pl~ 2003-03-30 13:49:11.000000000 +0200 +++ perl-5.8.0/ext/ODBM_File/hints/cygwin.pl 2003-03-30 13:49:11.000000000 +0200 @@ -1,2 +1,2 @@ # uses GDBM dbm compatibility feature -$self->{LIBS} = ['-lgdbm']; +$self->{LIBS} = ['-lgdbm_compat']; Gerrit -- =^..^= -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
