Hello,
i'm trying to remote debug a program running on an arm system running
linux but i ran into various problems. If i interrupt the
debugged program i can't get symbolic information where it stopped.
Also backtraces don't seem to work.

When test is statically linked everything works
as expected:

#6 0x0001a2e0 in vfprintf ()
#7 0x000088b0 in printf ()
#8 0x000081ec in main () at main.c:4
Therefore i tried to set a path for the
dynamic libraries but neither:
1)
set solib-absolute-prefix /usr/local/arm/arm-linux/
nor:
2)
set solib-absolute-prefix /dev/null
set solib-search-path /usr/local/arm/arm-linux/lib
had any effect.
Any ideas how i can fix this?
Regards,
Frank
