System: NetBSD black.invisible.ca 5.99.5 NetBSD 5.99.5 (GENERIC) #39: Mon Dec 15 20:56:04 EST 2008 jmcneill@black.invisible.ca:/export/home/jmcneill/branches/HEAD/src/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:
	/usr/bin/ldd on amd64 and sparc64 does not handle 32-bit binaries.
	Some 3rd party software requires a functional ldd to build.
>How-To-Repeat:
	$ uname -srm
	NetBSD 5.99.5 amd64
	$ ldd /usr/pkg32/bin/wine 
	ldd: /usr/pkg32/bin/wine: unrecognized file format
>Fix:
	Workaround: Copy ldd from a 32-bit machine and install as
	/usr/pkg32/bin/ldd.i386:

	$ file /usr/pkg32/bin/ldd.i386
	/usr/pkg32/bin/ldd.i386: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for NetBSD 4.0, not stripped

	$ /usr/pkg32/bin/ldd.i386 /usr/pkg32/bin/wine 
	/usr/pkg32/bin/wine:
	-lc.12 => /usr/lib/i386/libc.so.12
	-lossaudio.0 => /usr/lib/i386/libossaudio.so.0
	-li386.1 => /usr/lib/i386/libi386.so.1
	-lwine.1 => /usr/pkg32/lib/libwine.so.1
	-lpthread.0 => /usr/lib/i386/libpthread.so.0

	Then fix any packages that call ldd to honour ${LDD} and set
	LDD=/usr/pkg32/bin/ldd.i386 in mk.conf

 Wouldn't it be easier to provide /usr/bin/i386/ldd and have the 64-bit ldd
 call that?

 Yes, that's why this note is in the Workarounds: section.

i'll take this one on, i've almost got 64 bit ldd working on 32/64 bit
objects at the same time.

Subject: PR/40199 CVS commit: src/usr.bin/ldd
Date: Tue,  6 Jan 2009 03:59:57 +0000 (UTC)

 Module Name:	src
 Committed By:	mrg
 Date:		Tue Jan  6 03:59:57 UTC 2009

 Modified Files:
 	src/usr.bin/ldd: Makefile
 Added Files:
 	src/usr.bin/ldd: Makefile.common Makefile.elf ldd.c ldd.h ldd_aout.c
 	    ldd_elfxx.c
 	src/usr.bin/ldd/aout: Makefile
 	src/usr.bin/ldd/elf32: Makefile
 	src/usr.bin/ldd/elf64: Makefile
 Removed Files:
 	src/usr.bin/ldd/ldd_aout: Makefile ldd.c
 	src/usr.bin/ldd/ldd_elf: Makefile README ldd.c

 Log Message:
 - get rid of building an a.out-happy ldd (but keep supporting a.out
   binaries for the ELF version.)

 - convert a.out, elf32 and elf64 support into convience libraries and
   link them right ones in.  if elf_ldd() fails on 64 bit platforms,
   try elf32_ldd() before aout_ldd().

 now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
 and it seems that all the issues from README are gone too.

 move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
 grab these values via reach-over more easily.
 some fixes for PR#40170:
 - set NATIVE=yes in the environment for genscripts.sh
 - set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
 - set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
 - get rid of building an a.out-happy ldd (but keep supporting a.out
   binaries for the ELF version.)
 - convert a.out, elf32 and elf64 support into convience libraries and
   link them right ones in.  if elf_ldd() fails on 64 bit platforms,
   try elf32_ldd() before aout_ldd().
 now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
 and it seems that all the issues from README are gone too.
 add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
 *and _LP64.  necessary for 32/64 bit combo ldd support.
 - rework this a bunch to make it work inside /rescue/ldd.
 - fix alpha build.
 make sure we set LIBISPRIVATE.
 fixes build issues reported by moof.
