Description redhat-bugs 2001-02-05 22:26:57 UTC 
Hello.

(See bug 8250)

I disagree that this is an issue with the build environment.  I think a
build machine SHOULD be able to have a preload list without it affecting
the resulting RPM.  There is a discussion on the rpm-list regarding this
and the message at
http://www.redhat.com/mailing-lists/rpm-list/msg01941.html provides a very
elegant solution.  It uses objdump instead of ldd to obtain the requires
list.

Why not use this solution?

Changing component.
Comment 2 Jeff Johnson 2001-05-24 13:32:32 UTC 
There are two problems that I can see with using objdump -p rather than ldd:

1) objdump -p output does not include
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

2) objdump -p may not work with a.out executables.

Yes, there are possible workarounds for both problems. I still don't
believe that rpm defaults can possibly Get It Right for all build
systems, and so it's not worth attempting.

If you really want to eliminate LD_PRELOAD dependencies, then write your
own find-requires and filter out the unwanted dependencies:
	#!/bin/sh
	/usr/lib/rpm/find-requires | sed -e 's/whatever//'
and configure your build system by doing (assuming above script is
in /etc/rpm/my-find-requires):
	echo "%_find_requires /etc/rpm/my-find-requires"

A per-package configuration is also possible.
