前面省略下载Eclipse和Cygwin的过程。
下面记录下解决调试报错的问题的过程。
当写好程序，进入Debug时，会出现以下错误提示：
这时候点击“Edit Source Lookup Path”按钮，会出现以下画面：
点击“Add”按钮，再选择下图中的“Path Mapping”选项。
名字就命名为“Debug Mapping”，点击“Add”，依次填入以下信息：
Compilation path ——> /cygdrive/c
Local File System Path ——> C:\

原文如下：
I'm using cygwin and when launching the debugger, it complains that it can't find the source file
You must provide a mapping from /cygdrive/c to c:\ (or whatever your drive letter is).
To do this,
- From the editor error page, select the "Edit Source Lookup Path..." button and select the "Add..." button
- Or, in the eclipse IDE, go to menu Window -> Preferences -> C/C++ -> Debug-> Common Source Lookup Path -> Add.
- From the list of lookup containers, choose Path Mapping and OK. You get a New Mapping in the list.
- Select the mapping and then Edit. In the Modify the path mappings dialog, select Add, and then enter:
- /cygdrive/c as the compilation path and
- c:\ as the local file system path.
- Select OK, OK, OK to finish the dialogs.
- Terminate the debug session and restart; it should find your source files now.
This setting will apply to any debug sessions launched from this workspace.
You can also modify the settings in each individual launch configuration.
