在试图debugging代码的时候，我试图通过gdb在代码中放置break语句，但由于某些原因gdb没有看到源文件，尽pipe它在那里。 我第一次使用gdb，所以不知道这是否正确。 以下是terminal消息：
~$ cd ~/projects/bison/sandbox/2D-RZ_rodlet_10pellets ~/projects/bison/sandbox/2D-RZ_rodlet_10pellets$ gdb ../../bison-dbg GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.

(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find源文件为：
~/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
