ubuntu - GDB 看不到源文件

Question

在尝试调试代码时，我尝试通过 GDB 在代码中放置中断语句，但由于某些原因，GDB 看不到源文件，尽管它在那里。我是第一次使用 GDB，所以我不知道这是否是正确的方法。以下是终端消息:

~$ cd ~/projects/bison/sandbox/2D-RZ_rodlet_10pellets
~/projects/bison/sandbox/2D-RZ_rodlet_10pellets$ gdb ../../bison-dbg

(gdb) break ~/projects/bison/src/materials/NewMaterial.C:166
No source file named ~/projects/bison/src/materials/NewMaterial.C.
Make breakpoint pending on future shared library load? (y or [n])

我可以将源文件定位为:

~/projects/bison/src/materials$ ls | grep New
NewMaterial.C
NewMaterial.C~
NewMaterial.x86_64-unknown-linux-gnu.dbg.lo
NewMaterial.x86_64-unknown-linux-gnu.dbg.lo.d
NewMaterial.x86_64-unknown-linux-gnu.opt.lo
NewMaterial.x86_64-unknown-linux-gnu.opt.lo.d

Answer 1

不要使用带有 ~ 的文件名特点。 GDB 不会将它们扩展到您的 HOME 位置。

确保使用 -g 编译您的代码旗帜。

尝试仅使用文件名，如果它不是模棱两可的，那么:

break NewMaterial.C:166

如果不明确，请尝试将其与“编译根”相关的路径(例如项目根，就像它传递给编译器一样)一起使用。

作为最后的手段 - 使用完整路径(但字面意思是:完整路径，没有 ~ 字符)。
