In cross-compilation context, this is particularly a problem when loading a core file, because without the 'sysroot' specified in the gdbinit file, it will give a lot of warnings, like: warning: .dynamic section for "/lib/libstdc++.so.6" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/librt.so.1" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libm.so.6" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libgcc_s.so.1" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libc.so.6" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/ld-linux.so.2" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libanl.so.1" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libdl.so.2" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libpthread.so.0" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/usr/lib/libz.so.1" is not at the expected address (wrong library or version mismatch?) warning: .dynamic section for "/lib/libnss_files.so.2" is not at the expected address (wrong library or version mismatch?) warning: Could not load shared library symbols for 17 libraries, e.g. [...] Use the "info sharedlibrary" command to see the complete listing. Do you need "set solib-search-path" or "set sysroot"? In contrast, the '-ix' option will load the specified gdbinit file _before_ parsing object/core files. This will remove said warnings.
