gumstix gdb shared library problems

first posted at Gumstix http://www.nabble.com/gdb-problems-with-hello-world-td21286223.html

hi all,

gdb keeps complaining about not being able to find shared libraries even though they exist.

0x400009e0 in ?? ()
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.

Error while mapping shared library sections:
/lib/libc.so.0: No such file or directory.
Error while mapping shared library sections:
/lib/ld-uClibc.so.0: No such file or directory.
Error while reading shared library symbols:
/lib/libc.so.0: No such file or directory.
Error while reading shared library symbols:
/lib/ld-uClibc.so.0: No such file or directory.

Do I need to have something in my .gdbinit file? This was working fine under ubuntu 7.10 (no .gdbinit file there).

verdex xlp (tftp boot, nfsroot)
netmicroSD

current setup (doesn't work):
ubuntu 8.10

old setup (worked)
ubuntu 7.1

I get the following:
gumstix-gdb -s ./hello --dir ./ ./hello

Any clues?

thanks,

This is resolved by doing the following in gdb

set solib-absolute-prefix /home/hypo/gumstix/gumstix-buildroot-1614/build_arm_nofpu/staging_dir/lib/
set solib-search-path /home/hypo/gumstix/gumstix-buildroot-1614/build_arm_nofpu/staging_dir/lib/

i've added the above lines in my .gdbinit, so that this happens automatically whenever i start gumstix-gdb from ~/gumstix/gumstix-buildroot-1614

This issue was still happening. the following .gdbinit solved it for me:

set solib-absolute-prefix /dev/null
set solib-search-path /home/hypo/gumstix/gumstix-buildroot-1614/build_arm_nofpu/staging_dir/lib/
