GDB找不到源文件

Question

我將 GDB 與“Open On-Chip Debugger”項目一起使用來調試遠程 MIP 目標的交叉編譯項目，但由於某種原因，GDB 無法找到源文件。

在這里，我在目標 elf 文件上調用了 GDB。

development@ubuntu:~/vitessesdk/CEServices/build$ mipsel-vtss-elf-gdb obj/CEServices.elf

(gdb)

此時我輸入目標遠程命令進行連接

(gdb) target remote localhost:3333
Remote debugging using localhost:3333
0xa0000000 in ?? ()
(gdb) step

找不到當前函數的邊界

(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) 

我將列出目錄和文件。

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$

關於為什么會發生這種情況的任何想法？

Answer 1

閱讀有關GDB 中源路徑的部分。 您需要在(gdb)命令中使用dir命令。 迅速的。

Answer 2

事實證明，在發出“目標遠程本地主機：3333”后調試遠程目標時，我需要發出“加載”以將圖像加載到目標，因為我沒有在目標上運行 gdbserver。 加載后，它工作正常。 – 布魯斯·拉沃伊（Bruce Lavoie）剛才
