View Full Version : trouble with ddd

December 31st, 2009, 09:00 PM

I am trying to debug a program with ddd. When I try and load the program from the command line ($ddd Pong &) I get an error when ddd opens. I run make beforehand so the program is comiled. The error is: /home/.../init.c No such file or directory. However, there is no init.c in my directory. I don't seem to be having a problem when I use gdb so it seems to be something with ddd. Also, I tested ddd out using another program from the following site: http://www.ibm.com/developerworks/library/l-gdb/ while using the same exact makefile, and ddd loads this fine. Any ideas how to get ddd to open the file?

I was wrong, It won't work with gdb either. I use the SDL library in my program. Could this have anything to do with it?

Does your project have an 'init.c' file?

Did you compile your source files with the '-g' option?

Did you Google for "ddd init.c"? You may have found a link such as this one (http://www.linuxquestions.org/questions/programming-9/ddd-doesnt-work-226540/), which indicated that the '-g' option is indeed needed. Or maybe this link (http://expert.mandriva.com/question/49156). As you can see, the question has been asked and answered ad-nauseum. Hopefully the solution will work for you too.

I think I figured it out. I wasn't exactly sure where to put -g in Makefile. The place I had it allowed some programs to load and be debugged in ddd but not others. I moved -g and was able to get it to work in ddd. Hopefully this is the right place.

CXXFLAGS = -g -O2 -Wall -Werror -ansi
LDLIBS = -lSDL_image -lpthread
PROG = pong
NAME = pong
SRCS = main.cpp GameLoop.cpp Display.cpp Ball.cpp
OBJS = main.o GameLoop.o Display.o Ball.o

$(PROG): $(OBJS)
$(CXX) -o $(PROG) $(OBJS) $(LDLIBS)
#mv $(PROG) ..

# How to make the object files:

-include deps.mak

$(CXX) -MM $(SRCS) > deps.mak

# Cleaning target (only works with fileutils):

$(RM) $(OBJS) $(PROG)

Bulls-eye... you placed it in the correct spot.
