Problems debugging programs with shared libraries

[drjohn at pizero dot colorado dot edu (Doug Johnson)]

Greetings,

I am encountering a problem when I try to use gdb with programs that are
linked with shared libraries not included in the /etc/ld.so.conf
file. When I run ldd on the executable, all the shared libraries show up
with locations assigned to them. If I now run:

	gdb Program
        gdb> run

I get an error that gdb could find the shared library. If I now put the
directory in /etc/ld.so.conf and run ldconfig, gdb now finds the shared
library. The directory is included in LD_LIBRARY_PATH, this is how ldd
found it.

I am running on a Linux machine with RedHat 7.2, kernel 2.4.9-34 with
gdb verison 5.2. I have also seen this problem on other versions of
RedHat, and suspect that there is something strange about the local
configuration. I am also running amd, but have tried putting the shared
library on a local disk and modifying LD_LIBRARY_PATH appropriately;
still no luck.

Does anyone know the cause, and hopefully the solution, of this problem?

	Thanks,
	doug

   In the beginning there was nothing, Then nothing turned inside out
   and became something. When will you turn yourself inside out?
