Description Jimmie Mayfield 2003-07-10 23:16:11 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20021224

Description of problem:
In RH8.0, ldconfig seems to prepend /usr/lib and /lib to the list of directories
in /etc/ld.so.conf.  This behavior differs from earlier Redhat releases and it
makes it very difficult to override libraries.

For instance, I prefer to reserve /usr/lib for "distribution binaries" and place
customized or locally-built binaries in /usr/local/lib.  Unfortunately, this new
ldconfig behavior thwarts that since it seems to always place /usr/lib and /lib
at the top of the search path.

I've tried explicitly specifying /usr/lib and /lib in /etc/ld.so.conf to no
avail.  ldconfig complains that they've been specified twice (once in the
ld.so.conf and presumably once hard-coded in the ldconfig binary).

Making users explicitly set LD_LIBRARY_PATH is messy and, in fact, won't work in
the case of SUID binaries.  So it seems with RH8.0, the only way to override the
libraries in /usr/lib or /lib is to physically replace them. :(



Version-Release number of selected component (if applicable):
glibc-2.3.2-4.80.6

How reproducible:
Always

Steps to Reproduce:
1. ldconfig -v
2. 
3.
    

Actual Results:  note that /lib and /usr/lib appear ahead of anything listed in
/etc/ld.so.conf

Expected Results:  I would have expected those directories explicitly listed in
/etc/ld.so.conf to appear ahead of any default search paths.

This is fixed in glibc-2.3.2-69 and later.
