How to define shared libray symbol file for GDB in cross debug en vironment?

[Yu kenny-a18604]

Hi, all:

Here I have trouble in using GDB.

I am in a cross-compiler environment. Host is x86 PC and target is xscale-arm. I've been succeeding in connect arm-gdbserver from host PC. Also I loaded symbol file of my binary - elf.out. But now the trouble is:

There is some shared libraies like libmydb.so I want to load it in host as a symbol file. GDB 'sharedlibrary' command just search this shared-symbol-file in a fixed path - /usr/lib. I could not copy libmydb.so to /usr/lib cause there is a x86 shared library there with the same name. I can't change it now.

So my question is how to direct gdb-host to load shared library symbol file in specific path, for example, /myhome/target(/libmydb.so)?

Thanks in advance,

Kenny Yu (Xuanwei)

Look at "set solib-absolute-prefix" and "set solib-search-path".
