specifying the library path

specifying the library path

[Baurjan Ismagulov]

Hello,

how do I use a library from a different directory under gdb?

As I understand from the following page, gdb should use the inherited
LD_LIBRARY_PATH value:

http://lists.debian.org/debian-devel/2003/debian-devel-200301/msg01338.html


Here is what I am doing:

$ export LD_LIBRARY_PATH=/z
$ ldd /sbin/blogd
        libutil.so.1 => /lib64/libutil.so.1 (0x0000002a9566d000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000002a95770000)
        libc.so.6 => /z/libc.so.6 (0x0000002a9588c000)
        /lib64/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x0000002a95556000)
$ /usr/ibr/src/gdb-6.0/gdb/gdb /sbin/blogd /core

This GDB was configured as "x86_64-unknown-linux-gnu"...
Core was generated by `/sbin/blogd /dev/ttyS0'.

#0  0x0000002a958f6df4 in fileno_unlocked () from /lib64/libc.so.6

For now, I'm replacing the library in /lib64, but this is somewhat
inconvenient for libc...

Thanks in advance,
Baurjan.

Ah, the program that generated the core didn't use the library under /z
for some reason... Never mind.

With kind regards,
Baurjan.
