Excluding Dynamic Libraries

Greetings,

We are attempting to build an rpm for an embedded system
that does not 
require libbz2. No matter how much patching I seem to do, I
still cannot 
seem to get the rpm binary to build without requiring libbz2
at runtime. 
I've quite literally patched *ALL* references to libbz2,
bz2 and all 
possible variants therof out of the codebase. I'm at a
complete loss at 
this point. I even tried deleting libbz2 out of /usr/lib
(and then ran 
ldconfig), in an effort to get the build to give me *SOME*
sort of error 
message, but to no avail.

Codebase is 4.3.3, with RHEL 4 RPM package patches. How do I
build such an 
RPM that does not require libbz2 at runtime?

..Chuck..

Good, you've discovered the "--without-selinux"
./configure option 

Presumably you mean you want rpm-4.3.3 to build without
bzip2.

Have you tried
     rpm -e bzip2-devel?
and then building?

Otherwise edit config.h immediately after configuring and
nuke these  
lines

/* Define to 1 if you have the <bzlib.h> header file.
*/
#define HAVE_BZLIB_H 1

That should drop out bzip2.

Yup, but read on...

Yes.

Yup, tried that.

Did that, but no joy. Here's what I did:


apt-get source rpm
cd ~/rpmbuild/SPECS
rpmbuild -bp rpm.spec
cd ../BUILD/rpm-4.3.3
./confingure --prefix=/usr --sysconfdir=/etc
--localstatedir=/var  \ 
	--infodir='/usr/share/info'  --mandir='/usr/share/man'
	   \
	--without-python --enable-posixmutexes --without-javaglue 
\
	--without-selinux
make -j4

Finally, after the build, I did a:

cd .libs
ldd ./rpm

And here's the bad news:

        linux-gate.so.1 =>  (0xffffe000)
        librpm-4.3.so => /usr/lib/librpm-4.3.so

Arrrggggghhhhh, what am I doing wrong?
