what command in gdb is same as pathmap in dbx?

Question

When I use gdb on a coredump it reports some .so it cannot find in a certain path. For example:

Symbol file not found for /root/a/xx.so

I do not have administrator rights to create a directory in root, but I do have the xx.so, and in dbx, I can use pathmap to change the path where I can continue the debug. But in gdb I cannot find the same command.

In addition, I do not have the rights to change the compiler command. That is to say, I can't change the linker path to re-compile.

It sounds like you want set solib-search-path, which takes a colon-delimited list of directory names to search for shared libraries when searching in sysroot fails.

A related command, set sysroot (a.k.a set solib-absolute-prefix), allows you to set any directory as the root used for loading libraries with absolute path names, but you would need to insure that the libraries are laid out in the proper directory structure under the new root, and it sounds like you don't want to do this.
