GDB最多但并非全部源文件

Question

出于某种原因，即使使用相同的汇编目录，GDB也只会找到源文件的子集

例如一个例子：

#12 0xb5bf6b90 in services::dcs::NetworkDomainCollector::addDomain (...) at services/collect/dcs_NetworkDomainCollector.cpp:19

和

#14 0xb5d7a610 in framework::dom::OCObject::OCObject (...) at **/home/jenkins/workspace/Official_Builds_Pipeline**/mclinux/src/framework/dom/dom_OCObject.h:66

现在，对于我们的代码库，我们从McLinux中编译的根目录，但我最近意识到，许多文件（查看.o/gcov文件）显示它们是从mclinux/src/中汇编的，所以我想也许也许也许我只需要添加... mclinux和... mclinux/src作为“目录”参数，没有任何区别。

(gdb) info source
Current source file is services/collect/dcs_NetworkDomainCollector.cpp
Compilation directory is /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/src <== SAME
Located in /home/user/mcgit/code/FMW-74565/coredumpout_16_29_52/mclinux/src/services/collect/dcs_NetworkDomainCollector.cpp <== gdb files this file!

#14 0xb5d7a610 in framework::dom::OCObject::OCObject (...) at /some/dir/mclinux/src/framework/dom/dom_OCObject.h:66
66      /some/dir/mclinux/src/framework/dom/dom_OCObject.h: No such file or directory
(gdb) info source
Current source file is /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/src/framework/dom/dom_OCObject.h <== Naturally doesn't exist on my fs
Compilation directory is /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/src  <== SAME
<Not located by GDB>```

Is there any command I can use to see if gdb even tried to search down these paths?

Even trying to totally short circuit it with things like

    set substitute-path /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/src/framework/dom/ /home/user/mcgit/code/FMW-74565/coredumpout_16_29_52/mclinux/src/framework/dom/
or
    set substitute-path /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/src/ /home/user/mcgit/code/FMW-74565/coredumpout_16_29_52/mclinux/src/
or
    set substitute-path /home/jenkins/workspace/Official_Builds_Pipeline/mclinux/ /home/user/mcgit/code/FMW-74565/coredumpout_16_29_52/mclinux/

我会回答我自己的问题，最后与替换路径一起玩，但我意识到，尽管目录更改了，但执行“ BT”时GDB打印的路径不会随着新路径而更新。不确定这是否被视为错误？但是，如果进入框架，您将看到源数据。

当天的课程，不要以为替代路径失败，因为“ bt”仍然显示了旧路径。
