copying executable with shared lib

Tore_1 — Tue, 29 Oct 2002 08:47:12 GMT

Hi, say I want to copy /usr/sbin/lvdisplay
to /tmp and umount /usr.

chatr lvdisplay says :

lvdisplay:
shared executable
shared library dynamic path search:
SHLIB_PATH disabled second
embedded path disabled first Not Defined
shared library list:
dynamic /usr/lib/libc.2
shared library binding:
deferred
global hash table disabled
plabel caching disabled
global hash array size:1103
global hash array nbuckets:3
shared vtable support disabled
static branch prediction disabled
executable from stack: D (default)
kernel assisted branch prediction enabled
lazy swap allocation disabled
text segment locking disabled
data segment locking disabled
third quadrant private data space disabled
fourth quadrant private data space disabled
data page size: D (default)
instruction page size: D (default)

How can I change so that /tmp/lvdisplay uses library /tmp/libc.2 instead of /usr/lib/libc.2

Thanks in advance.

why don't you simply copy the /sbin version?

Hi,

instead of /usr/sbin
take the files from /sbin.
The /sbin versions uses no shared libs.

The /usr file system cannot be umounted in the multiuser mode.
You have to take the system down to the single user mode.
Lot of processes use /usr when the system is in the multiuser mode.
I used to re-build my application executables to give a different path of the shared library.

Not sure about OS commands.

Thanks

no, but it's a solution ;)

Use ld

Hi,

What is the point ?

I would have suggested to boot in lvm maintenance mode.

C.

the point is how to change the library list in an executable

TG : how do I do that (remember I only got the exe + libray, not the object file)?

rebuild the executables with the path specified as /tmp/lib....

Try enabling the use of SHLIB_PATH.
#chatr +s enable lvdisplay
#export SHLIB_PATH=${SHLIB_PATH}:/tmp

De.. I tried this (-s), but lvdisplay still uses /usr/lib/libc.2 (I ran it through tusc which showed that it open /usr/lib/libc.2)

chatr +s and SHLIB_PATH work for me-

% cp /usr/sbin/lvdisplay .
% chmod +w lvdisplay
% chatr -s +s enable lvdisplay
% cp /usr/lib/libc.2 .
% SHLIB_PATH=. tusc -s open lvdisplay
tusc: lvdisplay: No such file or directory

You may need to use "chatr -l library" if some of the libraries have static instead of dynamic paths. You will also have issues if some shared libraries depend on other shared libraries using paths that you don't like.
