With LD_LIBRARY_PATH set in ~/.bashrc   , gdb was loading misc library when
started from console.
However when started from emacs , as well as from kdevelop, it was not
loading misc

I solved it by adding to my .gdbinit
set solib-search-path /mnt/sda5/Programming/misc/src

It works also if I add to my prg's Makefile
g++ ....  -lmisc -Wl,-rpath=/mnt/sda5/Programming/misc/src

I see now it was a gdb issue, not an emacs or kdevelop one.
Thanks again.
