How to do remote debugging using gdbserver?

Question

I have one program that is getting segment fault. I need to debug that remotely. For that I am doing following:

On target board:

#gdbserver :2345 program

On host x86 machine:

$ arm-linux-gdb -q program
(gdb) target remote 192.168.150.104:2345

But after running above command I am getting number of errors:

Error while mapping shared library sections:
/usr/local/lib/QtTouchScreen/lib/libQtTest.so.4: No such file or directory.
Error while mapping shared library sections:
/usr/local/lib/QtTouchScreen/lib/libQtXml.so.4: No such file or directory.

Error while mapping shared library sections:
/lib/libm.so.0: No such file or directory.
Error while mapping shared library sections:
/lib/libgcc_s.so.1: No such file or directory.

I tried to set path of these libs on host where they are placed using export LD_LIBRARY_PATH, but still no luck.

Any help would be highly appreciated.

You need to set sysroot. If you have the libraries available locally, you can say:

set sysroot host-pathname
