Bad magic number for shared library

Vibhavari — Thu, 03 May 2007 05:11:53 GMT

I have compiled my C++ code on one HP-UX B11.11 server. When I copy the executable on other HP-UX B11.11 server and do ldd on it, it gives error as
/usr/lib/dld.sl: Bad magic number for shared library: /home/abhay/RangerRoot/lib/libaiframework.sl.0

Actually instead of above path it should pick the file from /disk2/rekhagc/RangerRoot/lib/.

The SHLIB_PATH and LD_LIBRARY_PATh are set properly.
echo $SHLIB_PATH
/disk2/rekhagc/RangerRoot/lib/:/disk2/rekhagc/RangerRoot/lib:/home/ranger1/Ora_DB_9i/lib32:/disk2/rekhagc/RangerRoot/lib:/disk2/rekhagc/RangerRoot/lib/:/home/ranger1/RangerRoot/lib/:/home/ranger1/tools/ncurses/usr/local/lib/:/home/ranger1/RangerRoot/lib:/home/ranger1/tools/gcc/usr/local/lib:/home/ranger1/tools/gcc/usr/local/lib:/usr/local/bin/iconv:/opt/java1.4/lib:/disk2/rekhagc/webserver/lib:/disk2/rekhagc/webserver/sbin/:/usr/lib:/home/ranger1/tools/ncurses/lib:/home/ranger1/Ora_DB_9i/lib:/usr/lib/:/disk2/rekhagc/RangerRoot/lib:/home/ranger1/ncurses/usr/local/lib/

Shalom,

This is an unusula place for required libraries:

/disk2/rekhagc/RangerRoot/lib/

Does it exist on the target system and was the application hard coded to look on a particular path or use SHLIB_PATH ?

The application is not hardcoded. The library is created and installed in RHOME/lib directory. The same library executable is supposed to use.

/usr/lib/dld.sl: Bad magic number for shared library: /home/abhay/RangerRoot/lib/libaiframework.sl.0

What does file(1) say about this file?

>Actually instead of above path it should pick the file from /disk2/rekhagc/RangerRoot/lib/.

ldd seems to indicate it once before the "not found" at the end.

>LD_LIBRARY_PATH are set properly.

This is not valid for PA32 executables.
