如何使 cscope 在搜索期间显示完整的文件路径答案

【问题描述】：

当我使用 cscope 搜索 C 符号或全局定义时，它会显示文件名和行号。我想查看完整的文件路径，以便我可以跳转到我的拱形特定文件。例如，在基于 Linux 代码库构建的 cscope 上搜索 __switch_to 的全局定义时，我得到：

Global definition: __switch_to

  File         Line
0 process.c    297 struct task_struct *__switch_to(struct task_struct *prev,
1 switch_to.h   44 #define __switch_to(prev,next,last) do { \
2 process.c    202 struct task_struct *__switch_to(struct task_struct *old,
3 process.c    400 struct task_struct *__switch_to(struct task_struct *prev,
4 process_32.c 211 __switch_to(struct task_struct *prev, struct task_struct *next)
5 process.c     80 void *__switch_to(struct task_struct *from, struct task_struct *to)
6 process_32.c 248 __switch_to(struct task_struct *prev_p, struct task_struct *next_p)
7 process_64.c 272 __switch_to(struct task_struct *prev_p, struct task_struct *next_p)

现在，每个arch 的文件process.c 都不同。如何让cscope显示完整的文件路径？

【解决方案1】：

使用 args -pn 运行 cscope

-pn 显示最后 n 个文件路径组件而不是默认值 (1)。使用 0 根本不显示文件名。

使用 cscope -p4 运行并搜索 __switch_to 的全局定义会导致

Global definition: __switch_to

  File                           Line
