Question

在尝试调试代码时，我试图通过gdb在代码中添加break语句，但由于某些原因gdb没有看到源文件，尽管它在那里。我是第一次使用gdb所以不知道这是不是正确的方法。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

吉安

请勿使用~个字符的文件名。 Gdb不会将它们扩展到您的HOME位置。
确保您的代码使用-g标记进行编译。
尝试仅使用文件名，如果它不含糊，那么：
break NewMaterial.C:166
如果不明确，请尝试将其与“编译根”相关的路径一起使用（例如，项目根目录，就像它传递给编译器一样）。
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~标志）。

gdb无法看到源文件
