Alright, well I found some weirdness:
[root@hagen ~]# export LD_LIBRARY_PATH=/usr/bin:/usr/lib:/usr/lib32:/usr/lib64
[root@hagen ~]# LD_DEBUG=1 ls
/libexec/ld-elf.so.1 is initialized, base address = 0x800506000
RTLD dynamic = 0x80062ad78
RTLD pltgot = 0x0
processing main program's program header
Filling in DT_DEBUG entry
lm_init("(null)")
loading LD_PRELOAD libraries
loading needed objects
Searching for "libutil.so.5"
Trying "/usr/bin/libutil.so.5"
Trying "/usr/lib/libutil.so.5"
Trying "/usr/lib32/libutil.so.5"
loading "/usr/lib32/libutil.so.5"
/libexec/ld-elf.so.1: /usr/lib32/libutil.so.5: unsupported file layout
That's because libutil.so.5 does not exist in /usr/lib only in /lib.
The /usr/lib directory has:
[root@hagen ~]# ls -l /usr/lib/libutil*
-r--r--r-- 1 root wheel 100518 Aug 21 2007 /usr/lib/libutil.a
lrwxrwxrwx 1 root wheel 17 Sep 11 11:44 /usr/lib/libutil.so ->
/lib/libutil.so.5
-r--r--r-- 1 root wheel 103846 Aug 21 2007 /usr/lib/libutil_p.a
So rtld is looking for major number 5 of libutil, without the standard
/lib in my LD_LIBRARY_PATH it searches /usr/lib, doesn't find it but:
[root@hagen ~]# ls -l /usr/lib32/libutil*
-r--r--r-- 1 root wheel 65274 Aug 21 2007 /usr/lib32/libutil.a
lrwxrwxrwx 1 root wheel 12 Sep 11 11:45 /usr/lib32/libutil.so ->
libutil.so.5
-r--r--r-- 1 root wheel 46872 Aug 21 2007 /usr/lib32/libutil.so.5
-r--r--r-- 1 root wheel 66918 Aug 21 2007 /usr/lib32/libutil_p.a
And whalah, I'm broke since there is a libutil.so.5 in there.
So my question to anyone out there, WHY does /usr/lib32 contain major
numbers but /usr/lib does not? This seems like a bug to me (FreeBSD
7.0-RELEASE is the same) or at least a dubious design decision.
Thanks!
