Source Path

The source path specifies the directories where the C and C++ source files are located.

If you are debugging a user-mode process on the computer where the executable file was built, and if the source files are still in their original location, the debugger can automatically locate the source files.

In most other situations, you have to set the source path or load the individual source files.

When you are performing remote debugging through the debugger, the debugging server uses the source path. If you are using WinDbg as your debugger, each debugging client also has its own local source path. All source-related commands access the source files on the local computer. You have to set the proper paths on any client or server that you want to use source commands.

This multiple-path system also enables a debugging client to use source-related commands without actually sharing the source files with other clients or with the server. This system is useful if there are private or confidential source files that one of the users has access to.

You can also load source files at any time, regardless of the source path.

Source Path Syntax

The debugger's source path is a string that consists of multiple directory paths, separated by semicolons.

Relative paths are supported. However, unless you always start the debugger from the same directory, you should add a drive letter or a network share before each path. Network shares are also supported.

Note If you are connected to a corporate network, the most efficient way to access source files is to use a source server. You can use a source server by using the srv\* string within your source path. For more information about source servers, see Using a Source Server.

Controlling the Source Path

To control the source path and local source path, you can do one of the following:

You can also directly open or close a source file by doing one of the following:

  • Use the lsf (Load or Unload Source File) command to open or close a source file.

  • (WinDbg only) Use the .open (Open Source File) command to open a source file.

  • (WinDbg only) Use the file | open source file command or press ctrl+o to open a source file. you can also use the open source file (ctrl+o) button (screen shot of the open source file button) on the toolbar.

    Note When you use File | Open Source File (or its shortcut menu or button equivalents) to open a source file, the path of that file is automatically appended to the source path.

  • (WinDbg only) Use the File | Recent Files command to open one of the four source files that you most recently opened in WinDbg.

  • (WinDbg only) Use the File | Close Current Window command or click the Close button in the corner of the Source window to close a source file.
