Hello I asked this question in other mailing lists, emacs, gnu gdb, gnu make, and it may well be a compiler problem. my compiler is gcc 3.3.5-3, the debian testing package. I read that "Executable programs sometimes do not record the directories of the source files from which they were compiled, just the names. I have this arrangement sam@debian:~/Exercies/ThinkingInC++/Vol1/C03$ tree . |-- makefile |-- 13 | |-- #rotation.cpp# | |-- bitwise.cpp | |-- makefile | |-- printBinary.cpp | |-- printBinary.h | |-- proj1 | |-- rotation.cpp | `-- semantic.cache |-- 14 | |-- #makefile# | |-- main.cpp | |-- makefile | |-- proj1 | |-- semantic.cache | `-- semantic.cache~ ../14/makefile looks like this ************************************************** include ../makefile in the parent directory I have this makefile ************************************************** OBJS = main.o CFLAGS= -g -Wall proj1 : $(OBJS) $(CXX) $(CFLAGS) -o $@ $(OBJS) #CC -o proj1 $(OBJS) the macro @ evaluates to the current target. clean : rm -f $(OBJS) I did sam@debian:~/Exercies/ThinkingInC++/Vol1/C03/13$ make which went ok. how can I know if the executable programs did or did not record the directories of the source files from which it was compiled. and if it did what are they? the reason I am asking is because when I Run gdb (like this): gdb ~/Exercies/ThinkingInC++/Vol1/C03/13/proj1 I get Current directory is /home/sam/Exercies/ThinkingInC++/Vol1/C03/13/ GNU gdb 6.3-debian Copyright 2004 Free Software Foundation, Inc.
