我总是在Linux中使用gdb，它工作正常，这是我第一次在mac中使用gdb，这与Linux不同。
(gdb) b main
Breakpoint 1 at 0x100000ec4
(gdb) r
Starting program: /Users/vinllen/code/tmp/lhm/homework

Breakpoint 1, 0x0000000100000ec4 in main ()
(gdb) l
No symbol table is loaded. Use the "file" command.
(gdb) n
Single stepping until exit from function main,
which has no line number information.
看起来命令l和n无法正确执行，有什么问题？
这是我的Makefile：
objects = main.o conversion.o slitemlist.o uims.o testdrivers.o
homework:$(objects)
g++ -o homework $(objects)
conversion.o: conversion.h base.h
slitemlist.o: slitemlist.h base.h
uims.o: conversion.h base.h conversion.h slitemlist.h
testdrivers.o: testdrivers.h
.PHONY: clean
clean:
rm homework $(objects)
最佳答案
这是我的Makefile：
在Linux上调试这个程序也不会很愉快：编译它时没有调试符号（标志-g）。
你真正的问题不是“如何在MacOS上使用GDB”，而是“如何编写Makefile以便调试”。
您应该在Makefile中添加这样的行：
CFLAGS = -g
CXFLAGS = -g # if building C++
