linux - gdb can not open shared object file

Question

I am trying to debug my application starting from console.

> gdb ./Geod

then in gdb

(gdb) run

and I get the output:

error while loading shared libraries: libGeo.Cored.so.1: 
cannot open shared object file: No such file or directory

The system is configured as follows:

> echo $LD_LIBRARY_PATH
    /home/paceholder/projects/geo/lib/debug

> ls $LD_LIBRARY_PATH
    libGeo.Cored.so.1.0.0
    libGeo.Cored.so 
    libGeo.Cored.so.1
    libGeo.Cored.so.1.0


(gdb) show solib-search-path
    The search path for loading non-absolute shared library symbol files is
    /home/paceholder/projects/geo/lib/debug.

You can use the set environment command in gdb to change the environment gdb uses to launch the program you want to debug. Extract from the gdb help:

(gdb) help set environment 
Set environment variable value to give the program.
Arguments are VAR VALUE where VAR is variable name and VALUE is value.
VALUES of environment variables are uninterpreted strings.
This does not affect the program until the next "run" command.

Example with LD_LIBRARY_PATH:

(gdb) set environment LD_LIBRARY_PATH /home/paceholder/projects/geo/lib/debug
