Cannot open 'file_name': File not found (/path/to/the/file)

  • 772

I compile a program with gcc. From VSCodeI open a font file, and I set a breakpoint.

Next, on the target machine, I launch the gdbserverwith the appropriate arguments. The debugger runs and waits for connections.

From VSCodethe debug view, I launch remote debugging. All correct, it connects to the gdbserver.

As soon as the breakpoint is hit, the source file is closed , and the VSCodedisplays the window with the warning:

Cannot open nombre-del-archivo: File not found (file:///full/path/to/the/file)

I'm building from a VM, where the project directory is correctly shared between Windows (host) and Linux (guest). From Linux, the shared folder (as shown in the image) is /media/sf_D_Drive.

Of course, the file that supposedly doesn't exist is present:

How VSCodedo I get the source file to not close, or show the error window, when I reach the breakpoint?

EDIT

I just realized the problem: I compile from the VM, but VSCodeI'm running it from the host machine; the executable has the paths relative to the VM, while the paths on Windows (host) are different.

Path on Linux:/media/sf_D_DRIVE/CMS/Subversion/CORE_5G/src/com

Path on Windows:D:\CMS\Subversion\CORE_5G\src\com

File .vscode\launch.json:

    You must set the source path using sourceFileMap, as explained here:

    Locate font files .

    You must add the following in launch.json:

    "sourceFileMap": { 
     "/media/sf_D_DRIVE/CMS/Subversion/": "D:/CMS/Subversion/" 
}

    You launch.jsonwill be like this:

    {
  // Use IntelliSense para saber los atributos posibles.  
  // Mantenga el puntero para ver las descripciones de los existentes atributos  
  // Para más información, visite:   go.microsoft.com/fwlink/…  
"version":"0.2.0",
   "configurations":[  
      {  
         "name":"(gdbserver) Launch",
         "type":"cppdbg",
         "request":"launch",
         "program":"${workspaceFolder}/bin/CFGP_bin_ConfigParam_cos",
         "args":[  

         ],
         "stopAtEntry":false,
         "cwd":"${workspaceFolder}",
         "environment":[  

         ],
         "externalConsole":true,
         "MIMode":"gdb",
         "miDebuggerPath":"c:/cygwin64/bin/gdb.exe",
         "miDebuggerServerAddress":"214.25.250.7:10000",
         "targetArchitecture":"x86",
         "linux":{  
            "MIMode":"gdb"
         },
         "windows":{  
            "MIMode":"gdb",
            "sourceFileMap":{  
               "/media/sf_D_DRIVE/CMS/Subversion/":"D:/CMS/Subversion/"
            }
         },
         "setupCommands":[  
            {  
               "description":"Enable pretty-printing for gdb",
               "text":"-enable-pretty-printing",
               "ignoreFailures":true
            }
         ]
      }
   ]
