如何获取GDB的行号？

Question

有没有具体的方法来做到这一点？我说的是一般用途.当我尝试在GDB中启动我的程序时,我收到此通知:

Reading symbols from /home/amsterdam/Code/c++/opengl_03/bin/opengl_03...(no debugging symbols found)...done.

这让我想知道我是否必须为此找到一个特定的文件？

更新

注意:我已经尝试过以下命令:

nm --debug-sym <your_executable> | grep debug

没有成功; 它拒绝显示任何东西.

这是我的Makefile:

BIN = bin/
OBJ = obj/
TARGET = opengl_03
DEPS = main.o  displayinit.o initializer.o algorithms.o matrix3f.o window.o vertex3.o
CC = g++
CFLAGS = -g -ggdb 
LIBS = -lglut -lGLEW -lGL 
INCLUDEPATH = -L/usr/include/ -L/usr/lib/ -L/usr/lib/x86_64-linux-gnu/

$(TARGET) : $(DEPS)
    $(CC) $(CFLAGS) -o $(BIN)$(TARGET) $(DEPS) $(LIBS) $(INCLUDEPATH) 

displayinit.o : displayinit.cpp displayinit.h
    $(CC) $(CFLAGS) -c displayinit.cpp  $(LIBS) $(INCLUDEPATH) #&& mv displayinit.o $(OBJ)displayinit.o
initializer.o : initializer.cpp initializer.h
    $(CC) $(CFLAGS) -c initializer.cpp $(OBJ) $(LIBS) $(INCLUDEPATH) 
algorithms.o : algorithms.cpp algorithms.h
    $(CC) $(CFLAGS) -c algorithms.cpp $(OBJ) $(LIBS) $(INCLUDEPATH) 
matrix3f.o : matrix3f.cpp matrix3f.h
    $(CC) $(CFLAGS)  -c matrix3f.cpp $(OBJ) $(LIBS) $(INCLUDEPATH) 
vertex3.o : vertex3.cpp vertex3.h
    $(CC) $(CFLAGS)  -c vertex3.cpp $(OBJ) $(LIBS) $(INCLUDEPATH) 
window.o : window.cpp window.h
    $(CC) $(CFLAGS) $(LIBS) $(INCLUDEPATH) -c window.cpp $(OBJ)
main.o : main.cpp
    $(CC) $(CFLAGS) $(LIBS) $(INCLUDEPATH) -c main.cpp $(OBJ)

编译时需要包含调试符号.例如,如果您使用gcc添加标志-ggdb.
