GDB看不到源文件(GDB cannot see source file)

虽然尝试调试代码，我试图把break语句通过GDB的代码，但由于某些原因，GDB没有看到源文件，虽然它的存在。 我使用GDB的第一次，所以我不知道这是否是正确的方式。 下面是该终端的消息：

~$ 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])

我可以找到源文件：

~/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:

1. 不要与使用文件名~字。 GDB不其拓展到你家的位置。
2. 确保你的代码得到与编译-g标志。

3. 尽量只使用文件名，如果不是暧昧，所以：

    break NewMaterial.C:166 

4. 如果它是不明确的，请尝试使用相关的“编制根”的路径中使用它（例如项目的根，只是因为它是传递到编译器）。

5. 作为最后的手段-使用完整路径（但字面上：完整路径，没有~字符）。
