我将 GDB 与“Open On-Chip Debugger”项目一起使用，以调试远程 MIP 目标的交叉编译项目，但出于某种原因，GDB 无法找到源文件。
这里我在目标 elf 文件上调用 GDB。
development@ubuntu:~/vitessesdk/CEServices/build$ mipsel-vtss-elf-gdb obj/CEServices.elf

****Reading symbols from obj/CEServices.elf...done.****
(gdb)
此时我输入目标远程命令进行连接
(gdb) target remote localhost:3333
Remote debugging using localhost:3333
0xa0000000 in ?? ()
(gdb) step
找不到当前函数的边界
(gdb) list
78 /home/development/vitesseSDK/CEServices/build/../third_party/eCos/packages/language/c/libc/startup/current/src/main.cxx: No such file or directory.
(gdb)
我将列出目录和文件。
development@ubuntu:~/vitessesdk/CEServices/build$ ls ../third_party/eCos/packages/language/c/libc/startup/current/src/main.cxx
../third_party/eCos/packages/language/c/libc/startup/current/src/main.cxx
development@ubuntu:~/vitessesdk/CEServices/build$
关于为什么会发生这种情况有什么想法吗？
最佳答案
阅读 GDB documentation 中有关源路径的部分.您需要使用 dir 命令，例如:
(gdb) dir path/to/sources
关于c++ - GDB 找不到源文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31035124/
