dbg debugger is not working properly [message #1248793]

Hi community,

i don't get gdb to work like it should. I had different errors, but now I think i am close to a solution (which i don't find).

My breakpoints are ignored and the error belonging is this (for all breakpoints there is one message):
16-break-insert /home/ponder/workspace/dtm/trunk/dtm/main.c:114
16^error,msg="No source file named /home/ponder/workspace/dtm/trunk/dtm/main.c."
(gdb)

But the mentioned path and file are exactly the right place where my sourcecode is stored.

Just to make sure: i used the -g and the -O0 option, i installed glibc-debuginfo (4.18-4.4.1) also the 32bit version and i am running an opensuse 13.1 x64 system

I imported this project and the Makefile was already there.
I don't have any Debug folder in this project, maybe that is the reason? Why is it not made? The debugegr is running through the hole code and also stops if i click on the suspend button. I never see the code just a "disassembly" message.

Does anybody has any ideas? If you need more information, please just ask.

Thanks in advance!
Anja

Did you specify the right executable in the Main subtab of your launch?
You can look at what is being sent as a parameter to the command -file-exec-and-symbols

Hi Marc,

thank you for your answer, but I am not sure if i got you right.

I loaded my sourcecode in gdb in my console.

gdb$ file /home/ponder/workspace/dtm/trunk/dtm/main
Reading symbols from /home/ponder/workspace/dtm/trunk/dtm/main...done.
gdb$ info args
No frame selected.
gdb$ exec-file
No executable file now.
gdb$ symbol-file /home/ponder/workspace/dtm/trunk/dtm/main
Reading symbols from /home/ponder/workspace/dtm/trunk/dtm/main...done.

But if i let it run it runs without any problems through the whole code.
I Did not write the code by myself, i just wanted to understand it (with some help of the debugger).

The executable in my maintab of my debug config is the same as in my normal launch conig. I read, that there should be a debug folder where it points to, but in my project the debug folder does not exist, and i don't know if i have to create it manually.

Sorry for being such a noob Embarrassed

Anja

Hi community,

until now i have not find my problems. I now try to debug in my console and it is not working either. So, maybe my Makefile is wrong?

.SUFFIXES: .c .u
CC= g++

LIB=../lib
GSLWRAP_LIB=../gslwrap
LOCAL_DIR=../local

CFLAGS = -g -o0 -I ${LIB} -I ${LIB}/math -I ${GSLWRAP_LIB}/include -I	\
  ${GSLWRAP_LIB}/include/gslwrap -I ${LOCAL_DIR}/include -I	\
  ${LIB}/util/gflags-1.1/src/gflags

GDB_CFLAGS = -ggdb -I ${LIB} -I ${LIB}/math -I ${GSLWRAP_LIB}/include	\
  -I ${GSLWRAP_LIB}/include/gslwrap -I ${LOCAL_DIR}/include -I		\
  ${LIB}/util/gflags-1.1/src/gflags

BASE_INCLUDES = -I ${LIB}

LDFLAGS = -L${LOCAL_DIR}/lib -L${LOCAL_DIR}/lib/stl -lgsl -lm -lgslcblas
LOBJECTS = ss-lm.o gsl-wrappers.o data.o param.o util.o lda-seq.o	\
  lda.o params.o main.o

GFLAGS = gflags.o gflags_reporting.o gflags_completions.o

all:	main

gflags:	${LIB}/util/gflags-1.1/src/gflags.cc
	$(CC) -c $(CFLAGS) \
        ${LIB}/util/gflags-1.1/src/gflags.cc \
        ${LIB}/util/gflags-1.1/src/gflags_reporting.cc \
        ${LIB}/util/gflags-1.1/src/gflags_completions.cc

main:	$(LOBJECTS) gflags
	$(CC) $(CFLAGS) $(LOBJECTS) $(GFLAGS) -o main $(LDFLAGS)

dbg:	$(LOBJECTS) gflags
	$(CC) $(GDB_CFLAGS) $(LOBJECTS) $(GFLAGS) -o main $(LDFLAGS)

clean:
	-rm -f *.o
	-rm -f main

I really really appreciate any help!!

Thank you for reading,
Anja
