[Windows]在Win7系统下搭建Eclipse+Cygwin开发环境

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,

1. 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.
2. From the list of lookup containers, choose Path Mapping and OK. You get a New Mapping in the list.
3. 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.
4. Select OK, OK, OK to finish the dialogs.
5. 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.
