Thread: mingw32 GDB No line information problem.

Hello!

I have this make file:

Code:

#===========================Basic Macros===========================#
COMPILER    = gcc


INCLUDES    = -IDependencies/SDL2-2.0.7/i686-w64-mingw32/include/SDL2 \
			  -IDependencies/SDL2_image-2.0.2/i686-w64-mingw32/include/SDL2 \
			  -IDependencies/SDL2_ttf-2.0.14/i686-w64-mingw32/include/SDL2 \
			  -IDependencies/SDL2_mixer-2.0.2/i686-w64-mingw32/include/SDL2


LIBRARIES   = -LDependencies/SDL2-2.0.7/i686-w64-mingw32/lib \
			  -LDependencies/SDL2_image-2.0.2/i686-w64-mingw32/lib \
			  -LDependencies/SDL2_ttf-2.0.14/i686-w64-mingw32/lib \
			  -LDependencies/SDL2_mixer-2.0.2/i686-w64-mingw32/lib


CFLAGS      = -g -Wall -c
LINKS       = -lmingw32 -lSDL2main -lSDL2 -lSDL2_image -lSDL2_ttf -lSDL2_mixer
#===========================Basic Macros===========================#




#Objects.
OBJECTS = main.o Core.o Window.o Events.o


all: main.exe


#Linking Everything.
main.exe: $(OBJECTS)
	$(COMPILER) $(LIBRARIES) -o main $(OBJECTS) $(LINKS)




#================================Compiling Source Files================================#


main.o: main.c TUC_Engine.h
	$(COMPILER) $(INCLUDES) $(CFLAGS) main.c -o main.o


Core.o: Core.c Core.h
	$(COMPILER) $(INCLUDES) $(CFLAGS) Core.c -o Core.o


Window.o: Window.c Window.h
	$(COMPILER) $(INCLUDES) $(CFLAGS) Window.c -o Window.o


Events.o: Events.c Events.h
	$(COMPILER) $(INCLUDES) $(CFLAGS) Events.c -o Events.o


#================================Compiling Source Files================================#




#Clean Rule.
#Remove .o and .exe files.
clean:
	del *.o *.exe

When i run main with gdb i get this:

Code:

(gdb) b main
Breakpoint 1 at 0x404510
(gdb) r

(gdb)

I tried to make a simple hello world program and run it with gdb and it works.

I'm probably doing something wrong in the makefile or because i'm using shared libraries has to do something with it.

Does anyone know what is wrong?

Thanks

I tried it, the result is the same

I also tried to compile it in a single line like this:

Code:

gcc <include paths> <link paths> -g -Wall -o main <source files> <shared_files>

But i get the same result.

I tried to use -ggdb both in the CFLAGS and in the LINKFLAGS and also i combined -g and -ggdb together but no luck, still the same
